Not that mad scientists haven't figured out a way to convert waste heat into energy, but a team from Ohio State University has developed a new material that does the same sort of thing... just way, way better. The new material goes by the name thallium-doped lead telluride, and at least in theory, it could actually convert exhaust heat from vehicles into electricity. According to a new report about to hit the journal Science, the material packs "twice the efficiency of anything currently on the market," though it still seems as if it's a good ways out from being ready for commercial applications. Nanotechnology geeks -- you've got a real treat waiting in the read link.

For those balking at the $2,000 price tag, you should really take a look at the competition before scrunching your nose up and walking away. That being said, two large is still a lot to drop on something that could still require at least some bodily exertion, but a recent video review over at Popular Mechanics could help you determine whether this particular bike is worth you while. The Giant Twist Freedom DX can roll up to 75 miles on a mixture of battery and human-powered pedaling, and the motor touts three different modes (Eco, Normal and Sport) to satisfy your mood / riding requirements. Nah, Ironman participants won't want anything to do with this heap, but those looking for a greener (and oftentimes quicker) way to commute in the city may find lots to love. The video, as promised, is waiting in the read link.

Though we're hesitant to believe something this fantastic could actually be implemented in real life, word on the pavement has it that Audi is currently running a pilot program that informs motorists "how fast to drive to catch a green light." Over in Ingolstadt, Germany, 50 traffic lights have been equipped with sensors that beam information to specially equipped whips; the network of "smart" signals not only "adapts to traffic patterns to deliver optimum light switching," but gives drivers a heads-up in order to get 'em through lights and cut down on idling / pollution / road rage. We can just hear those red light camera appeals now: "But judge, my car told me to do it!"

Not that electric MINIs are anything new, but unless you were willing to pay for all the mods yourself, procuring one wasn't exactly simple. Now, however, we're hearing that MINI itself will be bringing scads of these buggers to American streets in the summer of 2009. Yeah, like, one year from right now. MINI USA VP Jim McDowell was the source of said statement (so it's pretty much official, yeah?), though he didn't mention whether all of them would be reserved for California or if they would be available sold out nationwide. Hey MINI, we'd say you've got a hit on your hands.

Nah, ICP Solar isn't trying to help create the next solar-powered automobile (at least not with this initiative). Instead, it's looking to all but eliminate the hassle of returning to a vehicle with a dead battery. Said outfit has just entered into a sales agreement with both the European and North American branches of Nissan for OEM solar chargers, which would essentially juice up one's main battery while the sun beams down in a grocery store parking lot. Curiously, there's no mention of what vehicles this will be integrated into, so we'll just throw caution to the wind and expect to see 'em on every last motorcar it produces in 2009.

Oh sure, Rock Port, Missouri managed to snag the title of being "100% wind powered," but Texas' new plan will make the Show Me state's gusty initiatives look awfully weak. Officials at the Public Utility Commission recently okayed a plan to "build billions of dollars worth of new transmission lines to bring pollution-free energy from West Texas to urban areas." The ginormous Lone Star state is already the nation's leader in wind power, but when said plan is fully implemented (pending final approval), it'll produce more wind energy than the next closest 14 states combined. Granted, customers will be paying a touch more ($4 per month is the current estimate) for all this clean energy, but pundits assert that the cost is minor when looking at just how much this will help out Mother Earth. Look for everything to go live in four to five years, barring any unforeseen setbacks.

Never heard of Fresno-Yosemite International? Thanks to this low-key airport now housing the largest solar installation of any airport in the entire United States, you have now. Arriving passengers will notice the panels a half-mile out, as they cover about seven football fields worth of land and will eventually result in taxpayer savings of $11 million. The 2-megawatt farm has been churning out clean energy for the past month, and electricity from the installation helps to run "everything from airport lighting to tower communications." FYI's aviation director even noted that it would "produce about 40% of its annual electrical requirement." If you're worried that other locales won't follow suit, don't be -- a similar, albeit smaller system is already in the works at DEN.

According to Nikkei, Toyota's apparently going to be equipping future high-end Priuses with Kyocera-built roof-mounted solar panels. Somewhat counterintuitively, the sun's rays won't be used to power the car itself, but will instead run the AC. It also sounds like your next solar-assisted Prius won't be around for a while, as the panels aren't designed in yet, nor will they be until early next year when Toyota starts work on revamping the line.

While the rest of the world goes off to win the hearts of environmentalists (and laypeople, too) with LED light bulbs, Hitachi Lighting and Seiyu are taking the road (way) less traveled. Reportedly, the duo has collaborated in order to pop out a "bulb-shaped fluorescent lamp that can be separated into a lighting circuit unit and an arc tube unit." What this means is that the lighting circuit can be used repeatedly (up to 30,000 hours) while the arc tube simply gets replaced every 10,000 hours. The pair is hoping that the bulbs will take the place of traditional 60-watt incandescents, and considering that these only draw around 13-watts each, it's fairly easy to see how Mother Earth would just love you for making the switch. As for pricing, we're hearing that these will sell for around ¥1,500 ($14) apiece when they launch this October in Japan, so don't plan on recouping your investment in energy savings right away or anything.

Your dreams of riding in the ultimate cheapo deathbox have just gotten a little bit more real. According to a report, Tata will begin production of its diminutive, ultra-affordable Nano car this Fall. The $2500 vehicle is generally known as the cheapest car in the world, though worries over inflation suggest that its price-point may move above the intended figure. In other news, sources say that Tata plans a "greener" version of the vehicle in addition to the original model, which -- if it happens -- will likely be a real knockout punch for penny-pinchers with an Earth-hugging mindset. Still, you'll probably have to ship it from India, which would burn a lot of fossil fuels, which would be bad for the environment... oh just buy an old Yugo.

With just about every other automaker on the planet champing at the bit to showcase its newest electric prototypes, Subaru's doing its best to hang on to the briskly moving bandwagon. Said company has just recently announced that its plug-in STELLA concept will be showcased at the upcoming G8 Hokkaido Toyako Summit, and four of the five on hand will actually be used to "transport government officials and other participants" while the other offers itself up for test drives. The four-seat vehicle in question utilizes the same EV (electric vehicle) system employed in the R1e, suggesting that it can cruise around 80-kilometers (50 miles) on a full charge and hit a top speed of 100km/h (or just over 62mph).

While Audi is over there planning to produce an electric car within the next decade, Mercedes-Benz is hoping to be completely petro free within seven years. At least that's the word according to a recent report in The Sun. Dr. Herbert Kohler, who is responsible for Mercedes' advanced engineering, has reportedly suggested that "by 2015 motorists will have switched almost completely to alternative fuel cars." In order to make sure it's not left out, the automaker already has an electric car in the works for 2010 as well as plans to use its DiesOtto engine which will give motorists the ability to use biofuels should they choose. Still, aiming to phase petroleum completely out of its lineup by 2015 sounds overly ambitious from here, but we certainly won't complain if it achieves said goal.

Never mind those ginormous dam-based hydroelectric generators -- we've got a much smaller version that you can actually use in your backyard. The Pico Hydroelectric Generator was installed within a 5-gallon bucket by Sam Redfield in order to convert the energy from "existing gravity fed irrigation, fresh water, or waste water systems" into usable electricity that can juice up your cellphone, DAP, portable fan / water-bottle combo, etc. Regrettably, there's not a whole heap of details beyond that, but you can check out another angle in the read link below.

Look folks, just because Dyson can build a motor with enough oomph to power a vehicle, that doesn't mean it's actually going to. At least that's the message a company spokesperson wants you to believe. Contrary to earlier reports, James Dyson is not looking to enter the electric automobile sector in any way, shape or fashion. Said spokesperson was quoted as saying that "James Dyson did say that [Dyson's] new digital motor could power a car, but it is not working on, and [we] have no plans to create an electric car." Okay, but can you at least make the Ball 2.0 street legal?

Motorola so had this down pat last year, but we suppose O2 is just showcasing its pedal-powered charging system now that such devices are all the rage. Just days after we had a look at two unorthodox chargers from Orange, along comes rival O2 with a bicycle-related alternative. Reportedly, the eco-friendly device will be demonstrated at the O2 Wireless Festival in London's Hyde Park, but unfortunately, each of the demo bikes will be stationary. Still no word on whether O2 has a mind to take this thing commercial, but for cyclists the world over, here's to hoping it does.
