ELVIIS Volvo C30 EV charges from any standard outlet, bills the driver (hands-on)
The electric vehicle is still a fresh enough concept that the issue of redirecting the bill when filling up at a public outlet or a friend's house is of little concern. But once EVs gain more traction and the cost of electricity during that monthly dinner party starts to run upwards of 50 bucks, you'll definitely take notice. ELVIIS, a research collaboration between Ericsson and the Viktoria Institute in Sweden, may be the solution. Instead of pulling power from the grid blindly and billing the outlet's owner, the system provides driver and vehicle information to a server before charging begins, then redirects the cost for power consumed to whatever account you've registered with the vehicle, alleviating any concern about unexpected electricity bills. ELVIIS can theoretically serve other purposes, allowing you to select the least-expensive energy source, for example, or set the car to wait to charge until late-night, when rates are lower.We jumped into the passenger seat of one of five existing ELVIIS cars -- built around an all-electric Volvo C30 -- and poked around the charging interface. The project isn't fully operational just yet, and was running in demo mode so there's no way to verify that it works as described, but it definitely appears to be solid, with Ericsson providing financial and development support. Eventually, it will use the car's GPS to identify nearby power outlets -- for now, you need to enter a specific outlet ID. There's also an Android app that allows you to monitor and reschedule charging, so if you programmed your car to be completely charged by 7AM but realized that you need to leave at 6, you can make sure you're covered without getting out of bed. But you don't need to go anywhere to see it in action -- just click on past the break.
Cyborg cockroaches inch closer to reality, blame science
Few things on this planet are more indestructible than the lowly cockroach -- except, of course, a cyborg cockroach. That's what researchers at Case Western Reserve University are looking to create, and they're a lot closer than you may think. In fact, chemistry professor Daniel Scherson has found a way to harvest energy from the chemicals swimming within these insidious insects, meaning that they may soon be able to create robot cockroaches with a more reliable power source. To do this, Scherson and his team incorporated enzymes capable of converting a cockroach's food intake into electrons, which can then be funneled through a fuel cell to generate electricity. Unlike similar developments, Scherson's technique doesn't rely on an external source like light, movement or batteries. All you need is a cockroach and a steady food supply -- basically, a college dorm room. [Image courtesy of The Life Files]
This electric wire is four atoms thick, and you thought speaker cable was fiddly (video)
This should come as a great relief to anyone planning a quantum computer self-build: wires still conduct electricity and obey key laws of classical physics even when they're built at the nanoscale. Researchers at Purdue and Melbourne universities used chains of phosphorus atoms inside a silicon crystal to create a wire that's just four atoms wide and a single atom high -- 20 times smaller than the previous record-holder and infinitely narrower than anything you'd find at Newegg. The video after the break almost explains how they did it.
Onyx develops 330-watt 'plug-n-play' solar panel with built-in AC outlet
Onyx's new 330-watt solar panel isn't the first to offer a "plug-n-play" solution for getting power to your gadgets, but it may be the first to include a standard US power outlet, and enough output to juice up a computer, light or any other appliance (within reason) through its built-in micro inverter. "You can literally point the panel at the sun and plug an extension cord directly into the panel for immediate power," according to the Onyx PR, which you'll find in full just past the break.
Nissan Leaf to get inductive charging, lose its stem in 2013 (video)
Nissan has big plans for the still-budding Leaf. The Japanese automaker lit up its impressive Leaf-powered Smart House at the Tokyo Motor Show last week, but also demoed its wireless charging solution for a much smaller crowd at the company's Oppama factory. The device uses electromagnetic induction to transfer power between a charging pad and a receiver on the bottom of the car, with an efficiency level between 80 and 90 percent -- simply park your EV directly above the system to begin charging, and monitor progress on the ground transmission unit's control panel. The pad is expected to become available as soon as 2013, but will only be compatible with new vehicles, so you won't be able to use it with an older Leaf, unfortunately. There's a silent demo video waiting for you just past the break.
DCUO Lightning Strikes update to feature superhero origins content
By now you're probably aware of DC Universe Online's impending content pack. Lightning Strikes drops this Tuesday, December 6th, and in case you weren't already excited, PC Gamer's got a bit more for you to chew on. In addition to a new Central City map and a new set of electricity-based superpowers, DCUO is adding some origin content designed to titillate DC Comics fans and introduce newbs to the canon's long and storied history. Sony Online Entertainment creative director Jens Andersen told PC Gamer that the Flash's Cosmic Treadmill is the first of several origins-type devices slated to appear in the superhero MMO, and SOE plans to let players revisit "the origin stories of DC's biggest villains and heroes." The initial origin story occurs in one of DCUO's duo instances, where you and a friend will be whisked back in time to the night that Barry Allen rode the lightning and became The Flash. Head to the PC Gamer for the full article text, and check out the Lightning Strikes teaser video after the break.
New power set, Central City map coming to DCUO on December 6th
December 6th is shaping up to be quite a big day for Sony Online Entertainment. Not only is EverQuest II's latest expansion slated to debut, but so is the new Lightning Strikes content pack for DC Universe Online. The pack is free for subscribers and $9.99 for F2P folk. There's plenty of bang for your buck too, and it all starts with a new power set (electricity) and continues with new gear, a new open-world map (Central City), and plenty of new DC Comics characters and missions to populate it. New faces include Livewire, Black Lightning, The Top, and The Trickster, and you can learn more about DCUO -- as well as download the client -- at the game's official web destination, and we've tucked the newest trailer right after the break.
MIT slinks into a cafe, orders a side of photonic chips on silicon
Whiz-kids the world over have been making significant progress on the development of photonic chips -- devices that "use light beams instead of electrons to carry out their computational tasks." But now, MIT has taken the next major leap, filling in "a crucial piece of the puzzle" that just might allow for the creation of photonic chips on the standard silicon material that underlies most of today's electronics. Today, data can travel via light beams shot over through optical fibers, and once it arrives, it's "converted into electronic form, processed through electronic circuits and then converted back to light using a laser." What a waste. If MIT's research bears fruit, the resulting product could nix those extra steps, allowing the light signal to be processed directly. Caroline Ross, the Toyota Professor of Materials Science and Engineering at MIT, calls it a diode for light; to construct it, researchers had to locate a material that was both transparent and magnetic. In other words, a material that only exists in the Chamber of Secrets. Hit the source link for the rest of the tale.
AT&T exec discusses plans for home energy management service
Verizon has already dipped its toes into the home energy management business, and it looks like AT&T is about to do the same as well. Speaking on a Broadband Breakfast panel in Washington, DC last week, AT&T Executive Director of Public Policy Jeffery Dygert revealed that the company is "in the process of developing" its own home energy management system, which would let users monitor their electricity usage and manage its use more efficiently. That service is said to be a part of the company's broader Digital Life Project, and it will apparently be marketed to both AT&T's wireless and wireline customers, but details remain otherwise light for the time being. Hit the source link below for a video of the panel discussion.
IBM sees stacked silicon sitting in fluid as the way to power future PCs
Generally, the combination of microchips, electricity and fluids is usually considered an incredibly bad thing. IBM, however, thinks it can combine those three to make super small and super powerful computers in the future. The idea is to stack hundreds of silicon wafers and utilize dual fluidic networks between them to create 3D processors. In such a setup, one network carries in charged fluid to power the chip, while the second carries away the same fluid after it has picked up heat from the active transistors. Of course, 3D chips are already on the way, and liquid cooled components are nothing new, but powering a PC by fluids instead of wires has never been done before. Bruno Michel, who's leading Big Blue's research team, has high hopes for the technology, because future processors will need the extra cooling and reduced power consumption it can provide. Michel says he and his colleagues have demonstrated that it's possible to use a liquid to transfer power via a network of fluidic channels, and they to plan build a working prototype chip by 2014. If successful, your smartphone could eventually contain the power of the Watson supercomputer. Chop, chop, fellas, those futuristic fluidic networks aren't going to build themselves.

So what can players look forward to when Lightning Strikes? We sat down with some of the game's developers to find out, so follow on past the cut and have a gander.
Inhabitat's Week in Green: quantum levitation, Zombie-Powered Vertical Farm and Macquariums
Alternative transportation blasted off into the future this week as DeLorean revealed plans to launch an all-electric vehicle in 2013 and Richard Branson announced the official opening of the Virgin Galactic Gateway spaceport. Researchers also developed a next-gen quantum levitation technology that could lead to floating vehicles, and we spotted a cloud concept blimp that soars through the skies. We also brought you an exclusive interview with Revenge of the Electric Car director Chris Paine, and we shared a leaked brochure with specs on Toyota's new Prius C. Renewable energy also rocketed towards a more sustainable tomorrow as Japan's team Tokai took first place in the World Solar Challenge and Apple filed a set of patents for next-generation solar technology. Meanwhile Facebook announced plans to launch a new energy efficiency app in 2012 and we launched a contest where you can win one of 25 $600 home energy audits. We also showcased a stunning set of satellite photos of the world's power lines, and since Halloween is on its way, we brought you a Zombie-Powered Vertical Farm designed to keep its inhabitants safe from the Living Dead. Speaking of Halloween, this week we shared instructions for making a DIY cardboard box robot costume, and we launched our 2011 Green Halloween Costume Contest for kids. We also brought you several developments from the realm of eco textiles -- a material that repairs its own rips and tears and a Japanese company that recycles old bras into power-generating fuel. Finally, we showcased several slick developments in aqueous technology: an oil skimmer that cleans up spills four times faster, an artificial muscle that could one day propel nanobots through the body, and a quirky set of 'Macquariums' made from Apple iMacs.
Rohm Wireless Power Transmission system hands-on (video)
Wireless power demos abound at CEATEC, and Rohm Semiconductor had their own variant on hand with a complete mix of direct-draw gadgets, along with the omnipresent charging iPhone 4 (or was it a 4S?). Like Murata's prototype, the Rohm flavor uses square electrodes instead of the coils that you'll find in traditional wireless power solutions, like Qi. But unlike that seemingly identical solution from Murata, this version supports much greater power efficiency -- something in the 92 to 93 percent range (compared to the competing pad's 70-percent efficiency rating). That means that the prototype that we're looking at here loses just seven to eight percent of power during transmission -- which is still unacceptably high, mind you, but far more tolerable. Rohm's Wireless Power Transmission system also allows you to charge or power devices by placing them anywhere on the pad, rather than directly over charging positions, and it supports much greater transmission, with one prototype outputting up to 100 watts. Since power efficiency isn't something we could verify visually, what we could see at the company's demo did appear to work quite well. Powering a gadget is as simple as dropping it on the pad. Well, resting it gently -- this is a prototype we're talking about, after all. The 50-watt pad was able to power a fan, LED light, and a couple of charging smartphones without issue. The light and fan jumped to full power as soon as they made contact. A second pad got the juices flowing to a large OLED light panel, which was plenty bright when positioned on its own pad, but glowed quite dim when joining other devices. There weren't any charging laptops on hand, like we saw over at Murata, but with power output at 50 and 100 watts, either pad could theoretically support it. Like many of the prototypes we've seen at CEATEC, there aren't any plans to actually bring the system to market, but the technology could be used in other devices. We go hands-on after the break.%Gallery-135773%
Murata Wireless Power Transmission System supports laptops, we go hands-on (video)
Do we really need another wireless charging system that's incompatible with industry standards? Murata seems to think that we do. The company's prototype uses neither conductive nor inductive transmission, instead bringing its new capacitive coupling technology to the cordless charging mix. Capacitive coupling uses square transmitter and receiver electrodes, instead of the coils used with Qi devices. It also doesn't require a physical connection like near-obsolete conductive tech, which dictates that both the charging pad and receiving device use metal connectors that must be joined to transfer current. The Murata system is far from being production-ready, with only 70 percent efficiency (30 percent of electricity is lost during transmission). The sample the company had on hand can support 16 watts of output with a maximum of 2.1 amps, making each pad capable of charging several small gadgets, or one larger device, like a laptop. Murata seemed more interested in demonstrating the concept behind capacitive coupling than actually proving that it works -- the laptop we saw "charging" was a plastic mockup, though the base did glow red when the laptop's charging pad came into contact (though it also glowed blue at times, as you can see in the image above). We did take a close look at an iPhone case, however, which appeared to be remarkably thin -- much thinner than models from Powermat, for example, though the case does extend below the dock connector. Another advantage of the square electrodes is that you don't need to place devices in a certain position on the mat in order for them to charge -- they simply need to be positioned within the general charging area. We take a closer look in the video after the break.%Gallery-135770%
Piezoelectric system turns your balmy breath into pungent power
Researchers at the University of Wisconsin-Madison have come up with a way to produce electricity from just about the most renewable source known to man -- his own breath. It's all thanks to a plastic microbelt developed by engineers Xudong Wang, Chengliang Sun and Jian Shi. Made of a material known as polyvinylidene fluoride (PVDF), this belt produces an electric charge whenever low-speed airflow passes over it and causes it to vibrate -- a result of that vaunted piezoelectric effect. Eventually, Wang and his team were able to tinker with their system to the point where it could produce enough current to charge small electronic devices. "The airflow of normal human respiration is typically below about two meters per second," Wang explained. "We calculated that if we could make this material thin enough, small vibrations could produce a microwatt of electrical energy that could be useful for sensors or other devices implanted in the face." The researchers say their technology could be used to power smaller biomedical devices like blood monitors and pacemaker batteries, which typically don't demand vast amounts of energy. No word yet on when this system could make its way to the mainstream, but we'll be waiting with bated breath.
Microbial fuel cell produces hydrogen from wastewater without wasting energy
Back in 2005, Bruce Logan and his team of Penn State researchers developed a microbial fuel cell capable of converting poop into power. Now, Logan has refined his system to the point where it can produce hydrogen from wastewater or biodegradable organic materials without using a drop of grid electricity, and without emitting even a hint of carbon dioxide. His approach, outlined in the September 19th issue of the Proceedings of the National Academy of Sciences, involves something known as reverse-electrodialysis (RED) -- a process that harvests energy from the ionic discrepancy between fresh and salt water. Logan's bacterial hydrolysis cell (pictured left) features a so-called RED stack that's comprised of alternating positive and negative ion exchange membranes, which it uses to split water molecules into hydrogen and oxygen. Normally, this process would involve about 25 pairs of membranes, but by using RED technology in conjunction with electricity-producing exoelectrogenic bacteria, Penn State's team was able to extract hydrogen with just five membrane pairs. All told, Logan's cells proved to be about 58 to 64 percent energy efficient, while producing between 0.8 to 1.6 cubic meters of hydrogen for every cubic meter of liquid that passed through the system. The researchers' results show that only one percent of that energy was used to pump water through the cells, which are completely carbon neutral, as well. According to Logan, this breakthrough demonstrates that "pure hydrogen gas can efficiently be produced from virtually limitless supplies of seawater and river water and biodegradable organic matter." Somewhere, the US Navy is taking scrupulous notes. Full PR after the break. [Image courtesy of Penn State / Bruce Logan]
Superconducting sapphire wires are as cool as they sound
Copper wire's relatively cheap, pliable and can conduct electricity, but it's hardly ideal. Powering cities requires cables meters wide and the metal loses a lot of energy as heat. Fortunately, a team from Tel Aviv University thinks it's solved the problem. Borrowing a fiber of sapphire from the Oakridge National Lab in Tennessee, it developed a superconducting wire barely thicker than a human hair that conducts 40 times the electricity of its copper brethren. Cooled with liquid nitrogen, the sapphire superconductors carry current without heating up, which is key to their efficiency. The team is now working on practical applications of the technology -- because it's so small and pliable (unlike previous superconductors) it could replace copper in domestic settings and its cold efficiency makes it perfect to transmit power long distances from green energy stations. The wire's going on a world tour as we speak and will touch down at the ATSC conference in Baltimore in October. Anyone who makes jokes about wires and Baltimore will be asked to leave, politely.
EnergyHub's energy management system on sale now to American planetlovers

Inhabitat's Week in Green: Lighting superbike, kinetic energy generator and vibrating gloves
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. It's been an epic week for environmental news as Inhabitat reported that the East Coast battened its hatches against the force of Hurricane Irene, which has arrived in the wake of a 5.8 earthquake that shook the Eastern Seaboard from Virginia to New York. We compiled a series of tips to help our readers weather the storm, and we took a closer look at the six nuclear power plants that were shaken by the East Coast's unusual quake. We also showcased several incredible examples of high-tech architecture -- the recently crowned world's tallest LEED platinum building and the world's longest tunnel, which Russia recently announced would span the Bering Straight. Speaking of remarkable advancements in sustainable transportation, this week we took at look at what could be most powerful electric car on earth, and we brought you footage of the 200 mph Lighting superbike breaking a world land speed record. We also saw eco vehicles take off for greener horizons as Oliver VTOL unveiled an ultra-efficient airplane with 6 engines, a team of engineers in Africa constructed a DIY space shuttle in a local garden, and the flying ParaMoto Trike soared through the skies. On the topic of air travel, you may also want to check out our six tips for flying with small children (without Benadryl). It was a big week for wearable technology as well, as researchers unveiled a powerful kinetic energy generator that can fit in your sneakers. We also saw a vibrating glove that improves motor performance, a haptic glove that allows the blind to see with sonar, and a range of antenna-embedded clothing that offers a discreet form of hands-free communication. Finally, we heard Ashton Kutcher predict that wearable technology will be the next big wave, and we shared a glow-in-the-dark sequin gown that would make a choice piece of evening wear if this weekend's storm knocks the lights out.
Electrowetted insoles charge your strut, The Police stand by for music licensing deal
Every move you make is another ten watts you waste. Which is why researchers at InStep NanoPower are working towards taking that spring in your step, and turning it into juice for your gadgets. Flipping the process of electrowetting on its head, whereby mechanical energy is converted into electricity via a microfluid transfer, the team was able to pound some pavement-generated milliwatts out of mercury and galinstan. The tech is far from a real world debut, with its practical, portable device-powering merits achievable only in theory. So, until this device manages to get off the ground, we're going to lump it in with past piezoelectric efforts, and call it like it is -- pics, or it didn't happen.
