The 200-MPG Aerocycle

Dutch vehicle designer Allert Jacobs knew that his fuel-sipping, shell-encased motorcycle was street-legal. Unfortunately, the police didn’t, and impounded it after pulling him over during a test run.

But Jacobs has a lot of patience. He first built a resistance-reducing nose cone in 2007, in an attempt to increase his Honda Innova 125i’s 114-mpg rating. That design fell short, so he built a 1:5 scale model, followed by a full-size polyurethane and wood mold. By 2009, he was crafting the fiberglass shell. Steel tubes welded to the bike’s frame attach it, and a frame and rails added to the front of the bike allow the front of the shell to slide forward like a door and lock shut. Last winter, he even made aerodynamic cones with indicator lights for his side-view mirrors.

Most of the mileage boost comes from the aerodynamic shape, but Jacobs also converted the bike’s automatic clutch to manual to keep it from slipping. Altogether, the changes worked: On one long trip, the bike got 214 miles per gallon. And as for the impound? “I got it back,” he says, “and they had to apologize.”

Time: 3 years Cost: $5,000

HANDLING

Jacobs can put his feet down to steady himself when stopped, but the shell prevents him from planting them out wide. He’s considering building a new version with open sides in order to reduce balance issues.

COMFORT

After lowering the seat and raising the footrests above the wheel, Jacobs decided that they would improve steering if they were closer to the hub, so he welded tubes to the frame parallel to the front forks and attached the footrests to them.

SECURITY

Jacobs welded and bolted a steel rail to the front of the bike so that half the shell can slide forward 18 inches, allowing him easy access and exit. There’s a security bonus too, since he can lock up his bike along with any valuables inside.

3 More MPG-Boosting Mods

 

 

Duct-Taped Dream

Chang Ho Kim, who runs an auto-repair shop in Massachusetts, skipped doing airflow calculations and modified his 1989 Honda CRX HF largely on instinct. He added a narrow, wedge-shaped acrylic nose to move the air over the hood and roof, taped the seams between the body panels to prevent turbulence, and installed acrylic skirts to keep air flowing past the rear tires. An aerodynamic tail extends down off the hatchback glass. A few screws and lots of aluminum duct tape keep the pieces together. The mods yielded results: Previously, his Honda ran at 40 miles per gallon; now it routinely tops 60.

GREENIE VAN

Glass artist and furniture maker Marcus Sabathil’s Toyota Previa minivan is a moving example of his dedication to green principles: He increased its highway mileage from 20 mpg to 36. Sabathil made more than a dozen mechanical modifications, crafted a clear Lexan plastic aerodynamic tail with stainless-steel trim, and added interior side-view mirrors so he could fold in the outer ones on the road.

WONDER-TRAILER

Phil Knox, an aeromodding legend, attached an inverted and partially sawed-off boat to the top of a utility trailer and added fairings in front of and behind the wheels, as well as a smooth aluminum belly pan to reduce drag beneath the trailer. As a result, unlike normal trailers, Knox’s 430-pound creation—still awaiting a few tweaks before it’s finished—does not appear to reduce his pickup truck’s mileage.

New Generation of Supersonic Jets Aims to Get Rid of the Boom

True to its aeronautic roots, NASA is evaluating a new generation of supersonic airplane designs to see whether they can reduce sonic-boom levels.

Boeing and Lockheed Martin have submitted futuristic concepts that look similar to the Concorde, but aim to muffle the annoying and potentially damaging sonic boom problem.

Airplanes flying faster than sound create a cone of pressurized air molecules that extends to the ground, as NASA explains. The shockwave is noisy, but it can also cause structural damage, and in the Concorde's case, the U.S. wasn't having it. The supersonic jet never flew over land in the U.S.; sonic flights are restricted to military and research aircraft.

The new designs could make over-land travel possible, however, by using special engine or tail designs that reduce the shockwave effect.

The Lockheed design uses an inverted parabolic shape over a V-shaped engine array. The parabola would control air flow in a way that would lessen the shockwave, NASA says. It also has improved range, payload and environmentally friendly designs.

The Boeing concept, below, also uses a V-shaped twinned tail section, and like the Lockheed jet, it also places the engines on top of the wings. The Concorde, like nearly all current commercial aircraft, put the engines beneath the wings.

As Wired's Autopia blog notes, the design takes advantage of the wings as a natural sound barrier.

The planes are still a long way from takeoff -- NASA anticipates the aircraft could enter service by 2030 or 2035.

High-Pressure Process Yields a Brand-New Material That Stores Massive Amounts of Energy

With lackluster battery tech one of the biggest hurdles standing between existing energy economies and those of the green, renewable future, there's a lot of pressure on researchers to come up with the next big battery breakthrough. And pressure, it turns out, might be just the ticket. By exerting the kinds of super-high pressures found deep within the Earth on a unique compound, researchers at Washington State University's Pullman campus have created a novel new material with the capacity to store huge amounts of mechanical energy as potential chemical power.

Calling the material "the most condensed form of energy storage outside of nuclear energy," the researchers created the super-battery inside a diamond anvil cell, a small chamber that can create extremely high pressures within a confined space. The team filled the chamber with xenon difluoride, a white solid usually used to etch silicon conductors.

The science is in the squeezing; under normal atmospheric conditions, the molecules of xenon difluoride keep a respectable distance from one another. But under the intense pressures produced by the diamond anvils the molecules are forced together into metallic 3-D structures. At one million atmospheres -- roughly equivalent to the pressure found halfway to the center of the Earth -- the xenon difluoride is pressed neatly into these structures where the mechanical energy of all that pressure is stored in the chemical bonds between the molecules.

And just like that, the material becomes a chemical battery containing the mechanical energy from all that pressure. That raises the possibility of practical applications such as high-energy fuels, high-powered and compact batteries, or semiconductors that can function at very high temperatures.

Tiny Autonomous 'Copters Combine Voltron-Style To Create a Larger, Stronger Aircraft

Two rotors are better than one, and if our recent excitement over UPenn’s quadcopter is any indication, four rotors is better than two. Sometimes. Researchers at the ETH Zurich recognize that different tasks call for different aircraft, and with that in mind they’ve designed the Distributed Flight Array, a flying platform consisting of multiple small autonomous single rotor aircraft that can dock with one another to create a larger, more powerful aircraft.

The DFA, developed by ETH Zurich’s Institute for Dynamics Systems and Control, consists of multiple fixed propellor aircraft, each with its own sensors and flight control system. Individually, the components fly somewhat erratically, but joined together they become a larger sensor-based flight platform, capable of maintaining level flight by rapidly sharing data between them. When docked together, if something disturbs the array’s level flight each individual rotor can compensate appropriately to bring the system back into balance.

http://www.youtube.com/watch?v=7iHZKMDvdNI&feature=player_embedded

While the current DFA is a proof of concept, such a scheme could have a variety of applications, not least of which is the relatively straightforward yet sometimes difficult task of picking stuff up. Since the DFA is modular, users could deploy enough lift to execute a task without wasting resources on overkill. Further, its modular nature allows for some degree of failure within the system. If one or two of the bots fail, the others could compensate and even reconfigure to allow fresh bots to swap into the places of those that aren’t working.

Swapping components mid-flight might seem like tricky business, but considering how far researchers are coming along with these kinds of autonomous vehicles it’s certainly feasible. Just check out the video below, also from ETH’s Institute for Dynamics Systems and Control. These two quadcopters don’t just hover with precision. Their movements are so well choreographed, they actually dance with each other. No, seriously.

Four-Ton Transformer Tribute to Ancient Chinese General Meshes History and Sci-Fi

In the U.S., we often complete the run-up to graduation by writing 25 pages of extremely dry thesis that is typically read and appraised by a single person before being relegated to the library stacks forever. Bi Heng, a student at the Central Academy of Fine Arts in China, decided that instead he would create a 4-ton, $43,000 Transformer-inspired sculpture honoring legendary Chinese general Guan Yu.

The sculpture was assembled from components of an old Jiefang brand vehicle, a 25-year-old military service truck employed by the People’s Liberation Army. Robo Guan Yu stands about 32 feet tall and wields a dynastic-era weapon that makes for a nice juxtaposition with the post-Revolutionary scrap he’s assembled from.

As for the real Guan Yu, he was a respected general at the end of the Eastern Han Dynasty and a key player in the civil war that ended it. Though his military exploits and valor have been pumped up to mythical standards over the years, he was apparently legitimately revered for his prowess at kungfu. Though Robo Guan Yu is unfortunately static, check out the accompanying promo video below to see the general’s latest moves.

Stem-Cell Tourism: Adventures at the Fringes of Experimental Medicine

Droves of patients are heading overseas for stem-cell therapies unavailable in the U.S. Is it a dangerous scam or is America just behind the curve?

It’s 2:30 in the afternoon in the Dominican Republic, and Karen Velline, a 66-year-old grandmother from Cold Spring, Minnesota, is lying on an operating table, swaddled in sterile surgical sheets. She’s just moments away from a procedure so experimental that no doctor will perform it on U.S. soil. Yet she calmly stares up at the ceiling, more excited than anxious. Despite the controversy surrounding it, Velline believes that this procedure—which she has paid Regenocyte Therapeutic, a stem-cell company in Bonita Springs, Florida, $64,000 in cash to perform—could save her from a debilitating lung condition. After months of anticipation and planning, she’s ready for things to get under way.

Cardiologist Hector Rosario nods to his team and begins inserting a clear, narrow tube into a vein in Velline’s leg, slowly threading it all the way up to the right side of her heart. “That’s the catheter,” whispers medical supervisor Leonel Liriano, who has agreed to let me watch the surgery. I can see the tube moving on an x-ray imaging screen, inching closer to its final destination, the branched pulmonary arteries that supply blood to her lungs. With the catheter in place, Rosario reaches for a syringe filled with a solution of Velline’s own stem cells: the $64,000 potion. He inserts it into the catheter and depresses the plunger. A subsequent injection of saline serves as a chaser, ensuring that the cells migrate all the way to the lung vessels.

If the technique works as advertised, the cells—hand-couriered on a plane from Israel, where they were mixed with platelet growth factor to make them multiply, and delivered minutes ago to the operating room—will grow into the delicate gas-exchange regions of the lungs. Over several months, they should regenerate failing tissues that have been ravaged by Velline’s hypersensitivity pneumonitis, a degenerative lung disease caused by an allergic reaction to dust and chemicals that has left her dependent on three liters of oxygen a day. Doctors at the Mayo Clinic in Minnesota told her that the only hope of reversing her condition was a lung transplant, a high-risk procedure with a drawn-out recovery period. “That was something I didn’t want to consider,” she says.

Regenocyte presented an enticing alternative. Its glossy brochures and the effusive patient testimonials on its Web site offered hope that stem-cell therapy could not only keep her condition from getting worse but return her to her old self. If regenerative stem cells could help others, Velline reasoned, why couldn’t they help her too? As far as she was concerned, waiting years for the government to put its official seal of approval on the procedure wasn’t an option. She was dying.

Every year, hundreds of desperately ill Americans like Velline are making similar decisions, sidestepping government regulations and heading overseas to access a smorgasbord of stem-cell therapies unavailable in the U.S. Many of these treatments—offered by companies like Regenocyte, Germany’s XCell-Center and China’s Beike Biotechnology—involve autologous adult stem cells, meaning stem cells harvested from your own blood or bone marrow. These are thought to be safer than stem cells drawn from other donors or harvested from embryos, because they incur fewer risks of rejection or tumor formation. Just how safe, though, no one knows precisely, which is why the U.S. Food and Drug Administration insists on stringent regulations.

What's Truly New in iPhone 4

Apple, through powers of both good and evil, always finds a way to captivate like no other with their new product launches. But in unveiling the iPhone 4 today, they had an unfamiliar challenge to deal with: a world that has already seen in great detail the new product they were about to announce. So this time around, Apple had something more to prove: what exactly about the new iPhone 4 is new today?

Screen


We knew the next iPhone would have a higher-resolution screen, but the specifics are in, and they're pretty impressive. 960-by-640 pixels crammed into the same 3.5-inch screen of the 3GS. They're calling it the "Retina Display," and claiming it's the highest resolution screen ever in a phone (it bests the HTC Evo 4G's ginormous 800-by-480, 4.3-inch screen in both resolution and pixel density). Apple is clearly looking to recreate the "wow" factor of the iPad's high-res, color-rich screen by bringing 78 percent of the iPad's total pixel count to a screen less than half its size. Jobs claimed on stage that the human eye, from 10 to 12 inches away, can discern detail in a screen at up to 300 pixels per inch. And the iPhone 4's screen has 326 ppi, which means sharper text and UI elements all around (which will be natively up-res'd to some extent in existing apps).



Onboard Gyroscopes

Engineers have made great strides lately in making gyroscopes smaller, cheaper and more efficient, and they're clearly part of the next-generation in mobile motion-capturing sensors. The power of ubiquitous, low-cost accelerometers was introduced to the masses in Nintendo's Wiimotes, and since then they've trickled on down to just about every smartphone or mobile gadget on the market. And just as Nintendo achieved greater motion accuracy for their Wiimotes with the gyroscopic Motion Plus attachment, which pairs both sensors' inputs into true 1:1 motion capture, Apple is adding a 3-axis gyroscope to the iPhone for the same enhancement--another claimed first for a mobile phone.



Gyroscopes add fine-tuned rotational detection to accelerometers' ability to detect linear motion, so you can expect much greater accuracy from tilt-controlled games and other apps. Steve Jobs demonstrated a Jenga-like game for the iPhone on stage, and all I can say to that is yes.

HD Video Editing with iMovie


Several smartphones on the market now can capture the same 720p, 30fps video added to the new iPhone 4, but in addition, Apple demoed an impressive mobile version of iMovie that brings insanely powerful-looking onboard editing, rendering and export to your phone. Other phones can edit video too, sure, but what Apple showed today seems to go well beyond what's currently offered. If it works as advertised (and that's a big if, considering that I find the current desktop version of iMovie the most frustrating piece of software on my Mac), this is a huge leap forward.

Engineering


Apple loves their engineering wizardry, and with the iPhone 4, those strange gaps in the side of the frame that to many seemed unfinished have been revealed as something a bit more interesting: the stainless steel rim of the phone does double duty as a multi-purpose antenna for the phone's wide range of radio communications. It's crazy to think of how much transmission takes place, with GPS, Wi-Fi, Bluetooth, 3G data and cellular voice all having their own communications bands. Apple didn't hype any monumental gain in reception, but they did cite the antenna as the key to freeing up more room for a bigger battery that adds 40 percent more talk time.

Video Calling


Apple is promoting the iPhone 4's video calling, dubbed FaceTime, as a paradigm-shift in human communication. Maybe you've heard that before describing various video-calling products over the last decade, at least? So I'm not buying the brain-melting power of a video call on my iPhone just yet. What's interesting, though, is Jobs's announcement of FaceTime as an open standard. Details are vague at the moment, but if FaceTime became a de facto option for video calling on a host of different devices with webcams (and "just works" as so many Apple products claim to do), that could be an interesting development.



Also, for now, you're limited video chatting in a place with Wi-Fi, as the demand on AT&T's network would be extreme.

The Inside Story of the MotoCzysz E1pc, the World's Most Advanced Electric Motorcycle

This is the 2010 MotoCzysz E1pc, a race bike built by a tiny Oregonian company focused on pushing the limits of electric performance to the absolute max. It packs 10 times the battery capacity of a Toyota Prius and 2.5 times the torque of a Ducati 1198 into a package that looks like something out of a 24th-century Thunderdome.

Tomorrow it will race in the Isle of Man TT, the toughest motorcycle race in the world. The technology at work is so advanced, so unprecedented, that we may be looking not just at the future of motorcycles, but of all electric vehicles.

The reason the all-electric race bike is here, 4,600 miles from its home in Portland, Oregon, is to prove itself. Ever since 1907, the Isle of Man TT has been the race for bike manufacturers and riders to show their mettle to the public. The thinking goes that if you can lap its 37.7 miles of tiny, twisty back roads with an average speed in excess of 100 MPH, you or your bike become indisputably proven. Well over 200 riders and a handful of spectator’s have been killed trying to do just that.

But as recently as two days ago, the future of motorcycles was missing its body panels (stuck in customs). Before this week, the finished bike has never even seen the light of day. But even in its unproven, incomplete state, it's been putting in laps that have the competition quaking in their leather.

The customs snafu (and the mad dash to even finish the bike in time for the race) is not the first time Michael Czysz, MotoCzysz’s founder, CEO and the driving force behind the E1pc, had suffered a set back on this tiny rock in the middle of the Irish Sea. Last year, the Isle of Man TT hosted the first ever all-electric motorcycle road race, and MotoCzysz was there with the E1pc's predecessor. But while the machines that entered were technically impressive, their performance wasn’t. The race-winning team only averaged 87 MPH, well short of the 100 MPH watershed that defines a serious lap and way behind the 131.5 MPH lap record set by the fastest gas-powered superbikes. MotoCzysz didn’t even complete a full lap, suffering an electric spike from their experimental kinetic energy recovery system that fried the bike’s electronic control unit (ECU).

That was a major blow for Czysz (pronounced "sizz"). Five months of whirlwind effort from the former motorcycle racer and architect and his small team in Portland saw them abruptly transition away from developing a 200 HP, gasoline-powered MotoGP bike to produce an electric bike that blew the zero emissions competition away standing still. The E1pc looks like an X-Wing crossed with an iPod to the other electric racer’s cobbled-together adaptations of existing internal combustion engine bikes.

 

“We overreached and it bit us in the ass,” says Czysz of last year’s race. “We’re trying to do too much with too little, we’re effectively building a Formula One level machine with one engineer, two machinists, one CAD guy, me and a body dude.”

But the E1pc was out in front when it broke down. Way out front.

Remake, Remodel

This year’s all-new 2010 E1pc is too--out front, that is, not broken down. During practice this week, it reached a top speed of 140 MPH—besting its closest electric competitor’s 102 MPH. The E1pc also clocked a 94.6 MPH lap, tantalizingly close to the 100 MPH goal. Yes, it completed that lap. But that’s not the amazing thing; the E1pc ran that time while using, on average, less than 40 percent of its throttle and crossed the finish line, according to Czysz, with “plenty in reserve.”

 

But this new bike is way more than just an ECU that doesn’t blow and a bit more battery capacity. It’s a ground-up redesign of 2009’s largely off-the-shelf approach. “A bike has a relationship with the rider and a balance that is way beyond cars and computers, so you can’t just randomly shove stuff around and hope it works,” describes Czysz. “You have to work around the batteries, they’re they largest component, the heaviest component and the most important component.”

On the 2010 E1pc the batteries are huge, visually dominating the bike and occupying the space traditionally reserved for an internal combustion engine. There are 10 individual lithium polymer cells that each weigh 19.5 Lbs and were hand-assembled by a company that typically builds batteries for NASA. The level of integration here hints at the kind of work that’s gone into the rest of the bike. There are no wires connecting the batteries to the bike or any exposed terminals. Instead, posts on the batteries lock into receivers on the bike’s frame, at once making the electrical connection and supporting the batteries’ weight. The proprietary internal arrangement is secret, so we can’t show you a picture of it, but it allows the batteries to be swapped out in just a couple of seconds.

That ability is crucial. The electric motor is powerful enough to chew through the 12.5 kWh of on-board power in just 40 miles under race conditions (in comparison, the 2010 Toyota Prius's battery pack holds just 1.3 kWh and can travel only a single mile in full-electric mode). Quick-swap batteries allow the team to run road tests without waiting four hours between charges and, more importantly, removable batteries bring huge safety benefits. The E1pc is running close to the maximum allowable 500 volts, enough power to turn a wrench into molten metal in a flash of white light or split a mechanic’s hand in half (it’s already done the former). The ability to remove that power source from the bike before working on it renders the machine safe from accidental electric shocks. This level of safety and convenience have clear applications in mainstream electric consumer vehicles--don’t expect Czysz’s patents to stay on one-off race bikes.

But the custom-engineered, oil-cooled electric motor that sucks up those batteries’ juice may be the single most important individual component driving the E1pc’s exceptional performance; while most electric bikes repurpose electric motors built for forklifts or high-power drills, Czysz’s motor is the first to be developed from the ground up to win races.

The DC internal permanent magnet motor, which Czysz calls “D1g1tal Dr1ve,” is small enough to hide within the swingarm beneath the rear shock. The oil-cooled motor makes more power and torque than all three air-cooled motors in last year’s E1pc combined, while being smaller than one of them individually. And crucially, it develops its 100 HP and 250 Lb-Ft of torque continuously. Air-cooled electric motors, on the other hand, quote peak figures which they’re only able to reach for a very brief period of time due to the rapid buildup of immense heat. Sometimes, they can only reach peak power for a fraction of a second. The MotoCzysz can always make that 100 HP--as long as the batteries hold out, that is. The oil-cooling is key here, allowing the motor to exponentially shrink in size and weight for its output level; air-cooled motors are huge, so their large metal components can soak up the heat.

 

Despite batteries' limited ability to carry energy on board when compared to internal-combustion bikes, battery and motor together form a near ideal powertrain for racing. Adrian Hawkins, MotoCzysz’s lead engineer who left fabled engine design firm Cosworth to develop the E1pc’s electric drive technology, explains: “With the interncal-combustion engine, you’ve got a long way to go from where that throttle is: through the port, through the piston, through the combustion chamber, through the rod, through the clutch, through the gearbox, through the chain to the rear wheel.” In comparison, the E1pc’s electric motor offers a virtually direct connection between throttle and rear wheel. And for racing, that’s what engineers strive to develop. But power is not as important as control.

“I can pretension the chain with the throttle on that motorcycle,” says Czysz, explaining the implausible level of precision possible. “One percent throttle means one percent torque, it is the perfect drive. But now we have to work around all the other problems that aren’t perfect.”

First among those "other problems" is the constant struggle with a limited energy capacity and therefore limited power. Just as it’s pointless to pair a V12 engine with a two-gallon gas tank, there’s no point in carrying a motor that makes more power than the batteries can dish out. So a major design challenge for the E1pc is to insure it makes the most out of every single Lb-Ft of torque it makes.

“Ninety percent of a vehicle’s power is used simply to move the wind,” says Czysz, pointing out how aerodynamics play an even more important roll on electric vehicles than conventionally-powered ones (exhibit A: the Prius’s odd stub nose and compressed rump). Czysz has radically reduced the frontal area of this year’s bike — eyeballing the two next to each other, 2010 looks a third slimmer than 2009 — but it’s the wind’s exit that’s more important than its entrance.

“The low pressure area behind the bike is extremely vital,” explains Czysz. “That’s how planes work, the air accelerates so fast over the top of the wing that it creates low pressure that sucks the airplane up.”

So the challenge for a motorcycle aerodynamicist is to recombine the airflow behind the bike so it’s not sucked backwards as much as it is to split air cleanly around the front. Czysz also created ducts through the E1pc’s frame that suck air from the high-pressure area at the front through to the area beneath the seat, breaking up the low pressure. Gulfstream-jet-style winglets on the fairing whirl turbulence into these ducts just as the pull air rapidly through the motor and controller-cooling radiators.

The other extreme limiting factor to motorcycle aerodynamics is the big leather sack of human sitting on top, spoiling the airflow. Czysz has addressed this too, with perhaps the defining visual element of the 2010 E1pc. Turning to time trial bicycle racing for inspiration, he created a second riding position that the racer will move into on straights. By sliding their butt off the main seat and onto what's basically a modified pillion pad at the extreme rear, the rider adopts an incredibly low, flat-backed riding position that still gives them the ability to keep their feet on the foot pegs and hands on the handlebars; they can still fully control the bike in this position and even attack high speed corners by weighting the pegs and turning the bars.

All this aerodynamic innovation is reaping rewards on the racetrack. While competitors have adopted all-enclosed 1950s-style dustbin fairings that can negatively impact stability and therefore safety, Czysz is reaching far higher speeds using his modern methods.

The Complete Package

Every one of the E1pc's components — the motor, the controller, the battery packs, the aerodynamics — is all-new and class-leading, but they're not what makes the machine so special, the real trick here has been integrating all those into a whole that actually looks and functions like a motorcycle should; a rider accustomed to a gas bike will feel right at home on the MotoCzysz.

So what’s the ultimate payoff for all this besides a one-off, priceless prototype race bike? MotoCzysz does plan to develop its own range of production electric motorcycles eventually, but right now it’s about proving ideas, inventing technology and laying the groundwork for a future electric motorcycle industry. But don’t be disappointed if you want to get your hands on some of what you see here in the near future--the patents MotoCzysz is creating will probably appear on production machines from other manufacturers very soon. Indian automobile giant Bajaj, which plans to enter the US market in the near future, has partnered with Czysz for that reason. Hawkins’ talk of the perfect relationship between rear wheel and throttle is also revealing. That’s technology that could easily find a home in hybrid cars or applied to Kinetic Energy Recovery Systems that are popping up in race cars with increasing frequency. In fact, there’s a couple of distinctly four-wheeled vehicles hiding under tarpaulins in the MotoCzysz HQ right now. What they are or who they belong to Michael isn’t saying, but you can bet some of what you see here on the E1pc will end up on production vehicles in the very near future.

The 2010 MotoCzysz E1pc will be racing at the Isle of Man tomorrow (check back here for a followup on the results), and will return to America in July, where it will race at California's Laguna Seca in support of the US Grand Prix on the 25th.

Plastic Antibodies Shown to Fight Off Antigens in the Body Just Like the Real Thing

Artificial Antibodies Plastic antibodies like the ones clustered here could fight everything from viral infections to allergens in the bloodstream.

We use plastics to make everything from our computers to our toothbrushes, but a collaboration of researchers from the University of California at Irvine and the University of Shizuoka in Japan has made a big breakthrough by taking plastics to microscopic levels. Using plastic nanoparticles just 1/50,000th the width of a human hair, the team has created plastic antibodies that successfully function in the bloodstream of living animals to identify and fight a variety of antigens.

Antibodies are the proteins in our bodies produced by the immune system to recognize and neutralize foreign threats like infections, allergens, viruses and bacteria. These can include things as annoying but benign as plant pollen and dust to food allergens, bee venom, and other toxins. Our body produces antibodies in decent quantities, but in the case of allergies our immune systems can be unequipped to deal with certain antigens, and in other cases – such as a bad infection – our own natural antigens can simply become overwhelmed.

To counter these immune system shortcomings, the researchers took tiny plastic nanoparticles that had previously shown the ability to mimic natural antibodies. They then used a process known as molecular imprinting to stamp the shape of the antigen melittin, the primary toxin in bee venom, onto the antibody. By imprinting tiny antigen-shaped craters into the individual particles, the plastic antibodies were then finely tuned to attach themselves to those antigens in the blood.

The team then dosed a bunch of laboratory mice with lethal doses of melittin followed by an injection of the artificial antibodies. Those mice that received the antibodies showed a far higher survival rate, suggesting that the finely tuned plastic proteins can indeed track down and destroy threats within the living body.

The success of the molecular imprinting process coupled with the heightened survival rate of the mice suggests researchers could tailor a variety of these nanoparticles for use in just about any case where the body relies on antibodies for to fight off threats. That’s a lot of cases, opening the door to a synthetic immune booster that could potentially be used to treat myriad allergies, illnesses and infections.

Early-Adopting Dolphin Uses iPad Touchscreen to Communicate with Humans

Steve Jobs promised us the iPad would change our lives, and while it hasn’t been all things to all people – what about that front-facing camera, Steve? – the beauty of such a device is that developers (to the extent that Apple will allow them, anyhow) are free to get as creative as they want with the device. Just ask Merlin the bottlenose dolphin. He loves the iPad, and thanks to a symbol-based human-dolphin communication interface being developed for the iPad’s ample touchscreen, he could one day be able to tell you so himself.

The program, being developed by a non-profit called Speak Dolphin at Dolphin Discovery’s swim facility in Puerto Aventuras, Mexico, is being tested on both the iPad and a Panasonic Toughbook. Merlin, a two-year-old bottlenose, uses his rostrum (that’s his elongated beak) to operate the touchscreen, learning to associates symbols with objects.

Researchers think once Merlin gets the hang of using the touchscreen to associate objects, he’ll be able to learn a kind of symbolic language to express more intangible ideas, like actions or even emotions. Of course, this dolphin-human interface requires some other more basic technology beyond the program, like anti-glare screens that Merlin can better see and waterproofing tech that keeps him from ruining his favorite status symbol.

But what’s starting out as rudimentary symbol association on a touchscreen could potentially provide a way for humans to communicate quickly and efficiently, if at a very basic level, with the more intelligent species with which we share the planet. Add “Dog Whisperer” to the list of apps we’d like to see hit the store in coming years.

Nanowires Convert Rat's Heartbeat Into Usable Electricity

Nanowires inside a rat can convert the power of breathing and heartbeats into electricity, according to researchers at the Georgia Institute of Technology. The nano-generator could conceivably lead to nano-scale medical implants and sensors powered by the body.

The same GIT team proved five years ago that zinc oxide nanowires could produce electricity from a running hamster, for instance, or from tapping fingers. The wires produce electricity when under mechanical stress, called the piezoelectric effect. But now, it's been proven to work inside a living animal.

Zhong Lin Wang, a materials science and engineering professor at Georgia Tech, led the team that attached the nano-generator to a rat's diaphragm.

Researchers put a zinc oxide nanowire onto a flexible polymer and encapsulated it into a polymer casing to protect it from bodily fluids, Tech Review reports. When attached to the rat's diaphragm, the animal's breathing stretched the nanowire, and it generated a tiny amount of electricity -- about four pico-amps of current at two millivolts. When it was attached to the rat's heart, the nano-generator produced about 30 pico-amps at about three millivolts.

 

The rat generator operates at the femtowatt scale -- a pico-amp is a million millionth of an amp, so it is a tiny amount of current -- so not very much power. But the technology has potential to power nano-sized devices, Wang says in a paper on the results published in the journal Advanced Materials.

Wang's team is already building on the rat findings, Tech Review reports. The team has a device that integrates hundreds of nanowires into an array, giving an output current of about 100 nano-amps at 1.2 volts. The next step is to connect the higher-powered nano-generator inside an animal, Wang says.

 

New Cassini Findings Show Possible Signs of Methane-Based Life on Titan

Something is consuming hydrogen and organic molecules on Saturn's moon Titan, and the recipe matches astrobiologists' theories about possible methane-based life. Granted, there may be other chemical explanations . it's just that no one knows what they are yet.

New data from the Cassini spacecraft show hydrogen is disappearing near Titan's surface. What's more, scientists have not been able to find acetylene, an organic molecule that should be pretty abundant in the moon's thick atmosphere.

All this fits very nicely with a theory from NASA astrobiologist Chris McKay, who proposed five years ago that microbial life on Titan could breathe hydrogen and eat acetylene, producing methane as a result.

Scientists emphasize that the findings are not proof of life, and there's plenty of work to do before non-biological causes can be ruled out. Scientific conservatism suggests that a biological explanation should be the last choice after all non-biological explanations are addressed," says Mark Allen of NASA's Jet Propulsion Laboratory in Pasadena, Calif., in a NASA release.

The good news is that even if life is ruled out, the non-biological explanations are still interesting. According to previous studies, hydrogen should be distributed pretty evenly throughout Titan's atmosphere. But it's disappearing at the surface.

"It's as if you have a hose and you're squirting hydrogen onto the ground, but it's disappearing," says Darrell Strobel, a Cassini interdisciplinary scientist based at Johns Hopkins University in Baltimore, Md., who authored a paper published in the journal Icarus.

It's possible that the hydrogen is combining with carbon on Titan's surface to produce methane. But Titan is too cold for that to happen quickly enough to account for all the missing hydrogen. An unknown mineral could be the culprit, meaning scientists may have found a new substance previously unknown to exist on Titan.

The explanations for the dearth of acetylene are equally puzzling. The hydrocarbon should form abundantly in icy aerosols in Titan's atmosphere, but it's not there. It's possible that sunlight or cosmic rays are transforming the acetylene into more complex molecules that would fall to the ground with no acetylene signature, according to NASA.

It's also possible that chemical reactions are transforming acetylene into benzene (which Cassini did observe on Titan's surface), but that would require a catalyst, which hasn't been identified.

There's one more thing: Cassini observed an organic compound with the benzene that scientists have not been able to identify.

Cassini has several more Titan flybys in which to gather data in fact, the craft is set to fly within 2,000 miles of Titan's surface this afternoon, to make infrared scans of the moon's north polar region. The region includes Kraken Mare, the largest lake on Titan, which covers a greater area than the Caspian Sea on Earth. If methane-based microbes do live on Titan, there's a good chance they would live in just those sort of lakes.

How to Format a Hard Drive With Windows XP

If you want to format a hard drive while using or installing Windows XP, you've come to the right place. This can be very useful for clearing everything off a secondary drive or when installing a fresh copy of Windows. Formatting a computer hard drive is simple and can help eliminate viruses, storage issues and other hard-to-resolve problems.

Instructions

Step 1: When you format a computer hard drive you will lose everything that is on the drive. Therefore, it is very important to back up anything you might want later. Additionally, if you are going to be formatting and installing XP you need to make sure you have the discs for any applications or third party hardware you use since you will need to re-install your programs and drivers after re-installing Windows.

Step 2: Take a moment to think of anything that you have on the computer that you wouldn't want to lose. Generally, you probably want everything in your My Documents folder, and you also want to save things like your favorites or bookmarks from your Web browser. Remember that each user on the computer has his or her own My Documents folder, Desktop items and Favorites/Bookmarks.

Step 3: Save everything to a CD, DVD or a hard drive that you won't be formatting.

Formatting a Secondary Hard Drive


Step 1: Right-Click on the "My Computer" icon either on your desktop or in the Start Menu and select "Manage."

Step 2: A new window titled "Computer Management" comes up. Select "Storage" from the left hand side by clicking it once, then select "Disk Management(local)" from the right side by double-clicking it.

Step 3: Now in the lower part of the main frame (right side) of the window you should see a nice visual of all your hard drives. Each line is a different drive. Each box on a line (with a colored bar at the top and a size displayed in MB or GB) is a partition on the drive. Partitions are separations of space on a drive. Unless you are doing something specific that requires multiple partitions, you only want one partition per drive.

Step 4: First you must delete any existing partitions on the drive you are going to format. Do this by right-clicking on the partition's box and selecting "Delete Partition..." Since you already know that you will be deleting everything on the drive, and have already backed everything up, you can safely say yes to any warning the computer presents you with.

Step 5: If there are multiple partitions make sure you have saved everything off them since they might each have different drive letters (i.e. "D:" or "F:"). Then repeat the above step for each of them. If you only want to format one partition that is OK and you can continue to the next step without deleting the other partitions.

Step 6: The box for the drive to be formatted should now have a black bar at the top of it and should say "Unallocated" under its size (see picture). Right click on it and select "New Partition..." The New Partition Wizard comes up.

Step 7: In the New Partition Wizard click next. On the next page make sure "Primary Partition" is selected and click next. Now make the size equal to the maximum (it should already be set to it), and click next again. On the next page the computer will automatically choose the first available drive letter for the new drive. However, if you like you can choose another drive letter from the drop-down menu, and then click next.

Step 8: Finally the New Partition Wizard asks if you would like to format the new partition and if so what format. Choose "NTFS" as it is faster and more secure. Leave the "Allocation unit size" as "Default." In the "Volume label" field enter whatever name you want the drive to have. Simple is better. Avoid using spaces. Lastly, if the drive is brand new and has never been used before check the "Perform a quick format" box. If the drive has been used before leave this box unchecked. Leave the "Enable file and folder compression" box unchecked and click next. Then on the next page click finish.

Step 9: The wizard will now spend a little while formatting the drive. On old or large drives this may take a while. Do not close the "Computer Management" window until it finishes. You will know it is done when the word under the size of the drive changes from "Formatting" to "Healthy" and the name and drive letter you chose for the new drive show up. After it is finished you can proceed to use your newly formatted drive.

Formatting and Installing from the Windows XP CD

Step 1: This section explains how to reformat a drive from the Windows XP installation CD. This can be used when installing a fresh copy of Windows onto a computer. Here it is especially important to backup all of your important information because upon formatting you will lose EVERYTHING that used to be on the drive. This includes all applications and device drivers, so you must back up everything you can.

Step 2: Insert your Windows XP installation disc into your CD drive (Home or Pro--it does not matter).

Step 3: Now as you computer boots a little more it will say "Press any key to boot from CD.." press a key to do so.

Step 4: The CD will load up a blue screen and then spend a while loading files it needs. When it is finished it will list a few options, mainly "Press ENTER to set up Windows XP." Press Enter or Return.

Step 5: Now you will be at a screen to select where to install Windows to. This is where you can delete old partitions and format drives. The box in the bottom half of the screen shows all your drives and the partitions that exist on them. Use the Up and Down arrow keys to highlight your "C:" partition and press the 'D' key (if all that shows up is "Unpartitioned space" and you have no C: or D: partitions, skip this step). On the next screen press the 'L' key to finalize deleting the partition.

Step 6: Now you are back on the screen to choose where to install Windows. The box on the lower half of the screen should no longer show a partition but simply have an entry "Unpartitioned space xxxxxMB." Select this with the arrow keys and press the 'C' key to create a partition on the drive. The next screen tells you the minimum and maximum sizes the partition can be and lets you pick the size. The default size is the maximum, but double check that the number entered is the maximum and hit enter.

Step 7: Now you will again be back at the choose where to install Windows screen. But this time you will have a partition that looks something like this "C: Partition1 [New (Raw)]xxxxxxMB." Highlight this entry and press enter.

Step 8: The next screen lets you choose which file system to format the drive with. Choose NTFS as it is faster and more secure. If the drive is brand new and has never been used before then use one of the options that ends in "(Quick)." Or, choose one of the lower down options. Use the arrow keys to select the proper one and press Enter or Return.

Step 9: From here you are all set and the installation of Windows will proceed starting with a format of your drive. This will take a while (over half an hour) so you can take a little break.

Tips & Warnings

YOU MUST BACKUP BEFORE FORMATTING OR YOU WILL LOSE DATA YOU NEED.

How to Make Custom iPhone Ringtones for Free

So you bought an iPhone. You love the phone and all its features, but wish you didn't have to pay for your songs twice to get a ringtone. There are plenty of songs in your music library, but no way to make ringtones from any of them. Or is there? Actually, with a little bit of trickery (nothing illegal), you can create ringtones from any one of your non-DRM songs in your iTunes library easily and for free. This works on both Mac and Windows PCs.

*Please note: There may be differences among all the possible combinations of iTunes versions and operating system versions (see Tips for a way to work around the syncing issues).

Things You'll Need:
•iTunes
•Mac or Windows computer
•Non-DRM song (i.e., one not bought from the iTune`s Store).

Instructions

Step 1: Open iTunes.

Step 2: Find the song that you want to make into a ringtone.

Step 3: Listen to the song and find the part of it you want to use. The chorus may be a good place to start.

Step 4: Write down the start and stop times of the clip.

Step 5: Right-click the song and select "Get Info."

Step 6: Click the "Options" tab.

Step 7: Type in the start time of your ringtone in the text box next to "Start Time" in the minutes:seconds (i.e., 2:01) format.

Step 8:

Type in the end time of your ringtone in the text box next to "Stop Time." Make sure the ringtone is no more than 40 seconds long.

Step 9: Click "OK."

Step 10: Right-click your song again and select "Convert Selection to AAC." Wait for iTunes to convert your song. It will create a duplicate version.

Step 11: Right-click the ringtone and select "Delete."

Step 12: Click on the "Keep Files" button.

Step 13: Find the file. It's usually in your User folder under "Music > iTunes > iTunes Music" and under the band's name. It will have an extension of m4a.

Step 14: Replace the m4a extension of your ringtone with m4r. You can either double-click slowly to rename your file, or right-click and select "Get Info" on a Mac or "Rename" on a Windows PC.

Step 15: Click "Use .m4r" or the PC equivalent when the system warns you that the change may affect the use of your file.

Step 16: Double-click the ringtone file. ITunes will automatically add it to your ringtones folder in your iTunes Music Library.

Step 17: Connect your iPhone and sync your ringtones.

Researchers Achieve Quantum Teleportation Over 10 Miles of Empty Space

Scientists in China have broken the record for quantum teleportation, achieving a distance of about 10 miles, according to a new study in Nature Photonics. That's a giant leap from previous achievements.

The feat brings us closer to communicating information without needing a traditional signal transmission.

Although it's called teleportation, no matter is really moved. Rather, the quantum state of one object is transferred to another object.

It works by entangling two objects, like photons or ions. The first teleportation experiments involved beams of light. Once the objects are entangled, they're connected by an invisible wave, like a thread or umbilical cord. That means when something is done to one object, it immediately happens to the other object, too. Einstein called this "spooky action at a distance."

Until now, this has only been achieved with particles that are at most a couple hundred feet apart. And those distances have been accomplished with fiber channels, which help preserve the photons' state.

In the latest experiment, researchers entangled two photons and zapped the higher-energy one through a special 10-mile-long free-space tunnel, instead of a fiber one. The distant photon was still able to respond to the changes in state of the photon left behind, an unprecedented achievement.

It worked because the team "maximally entangled" the photons, using spatial and polarization modes, according to Ars Technica. About 89 percent of the information was maintained, also an improvement over previous experiments.

The work was done at the Hefei National Laboratory for Physical Sciences at Microscale and the Department of Modern Physics, University of Science and Technology of China, Hefei.

Though a 10-mile teleportation is impressive, there's still a long way to go before information can safely be sent this way. Photons are good at transmitting information, but ions are better at allowing manipulation, which would be necessary for encryption.

You Built What?! A Real Iron Man Suit

A Real Iron Man The material Le used for the armor is thin but takes stress well. “You can throw it against the wall, and it won’t even be damaged,” he says.
Anthony Le, 25, has been a fan of Iron Man since he was a kid, but when he heard that the comic-book superhero was hitting the big screen in 2008, he was inspired to build his own Iron Man suit. That version was more of a costume, but his new one, finished just in time for the movie’s sequel, edges much closer to the real thing. With its dent-proof exterior, motorized faceplate and spinning mock Gatling gun, his take on the movie’s War Machine suit could easily frighten a supervillain.

Le, a fitness consultant, studied some concept sketches of the suit posted on the Internet. He used thin, high-impact urethane for the armor, cutting it into plates and joining them with some 1,500 rivets and washers. He sculpted a clay helmet mold and then used a liquid resin mix to create the final product. But that was just cosmetic work. He also added a small servo motor that opens the faceplate, as in the movie, and built a gun out of pipes and a motor. LEDs in the eyes and chest-plate further add to the illusion.

Le plans to wear the suit to the movie and already has quite a following, especially at sci-fi conventions. “I’m kind of hard to miss,” he says.

How It Works
Time: 1 Month
Cost: $4,000+

WEAPONRY
Le built a replica of the machine gun on the suit’s shoulder out of PVC pipes and other materials. He added a small motor and belt drive to make the cylindrical gun spin like the real thing. To activate it, he presses a button in the palm of the suit’s glove. He says the gun could also be converted into a paintball shooter.

POWER
Le built an LED-based replica of Iron Man alter ego Tony Stark’s arc reactor for the chest, but unlike the movie version, it doesn’t actually power the suit. Instead, all the LEDs and the motors that drive the gun and the faceplate have their own batteries hidden within the suit’s large frame.

CONTROLS
Inside the chestplate, Le added a hands-free button that activates the helmet. When the faceplate is open, he just stands up and points his arm forward, causing his chest to press against the button, triggering the servo motors in the helmet to close the mask. This, in turn, switches on the red LEDs set inside the eye openings, which are large enough for him to also see out of. To open the mask up again, he presses another button.

BACKUP
Le says he focused on the War Machine suit, donned by Stark’s buddy Jim Rhodes in Iron Man 2, in part because “it just looks more hardcore.” But he also built a new-and-improved replica of the suit that Iron Man himself wears in the film, the Mark VI. That version also has the LEDs and motorized faceplate but, alas, no cannon.
