OSU Buckeye Bullet 2 sets new battery-powered speed record
Ohio State's Buckeye Bullet 2 has just set a new battery-powered vehicle record after hitting a speed of 291 mph averaged over two separate runs done back-to-back in opposite directions. Yes, it's technically slower than the two-way land speed record of 300.992 mph the original Bullet set back in 2009, but that car was powered by hydrogen fuel cells. This year's model instead was developed in partnership with boutique Monaco-based electric car manufacturer Venturi and replaced the fuel cells with lithium-ion batteries from A123 Systems. It's also apparently a testing prototype for a new car that's coming in 2011. Will that car hit these kind of world record speeds? Probably not, but we're not letting that dash our newly formed geek fantasy of seeing it drag against a Tesla.
HydroPak water-activated fuel-cell generator unveiled
While still quite a ways away from our ideal method of drawing power directly from tap water, the new HydroPak generator from Millennium Cell and Horizon Fuel Cell at least trumps those heavy, dirty, traditional models in both cleanliness and efficiency. As we first heard a few months back, this water-activated, fuel cell-based "portable power product" uses $20 disposable cartridges to provide "enough energy to recharge an average notebook computer 8 to 10 times" or "operate low power devices such as portable lights, notebook computers, portable televisions and ad hoc communications networks for more than 14 continuous hours," via AC outlet or dual USB jacks. Also on display at CES alongside the $400 unit will be a smaller version called the HydroPak Mini, a prototype device designed to juice up gadgets such as cellphones or gaming systems.[Via Gadget Lab]
Valeswood's Pearl: the hydrogen powered bike
Listen -- we know you want to do your part for the environment, but you don't have to wear jean shorts while doing it. By all means, take a gander at the Valeswood Pearl hydrogen-fueled, power-assisted bicycle, which motors up to 15 MPH and takes you about 80 miles before you need to juice the batteries. When you're finished with all the hard labor of pedaling, the bike folds up neatly and can be tucked away in the trunk of your 9 MPG SUV. If you're the eco-centric cat or kitten that we think you are, you're not going to be too miffed about that $4000 price tag, and we're sure the only kind of short you'll be rocking will be of the organic hemp variety. We wish we could say the same for the chap in the photo.
Cubic zirconia used to make fuel cells run cooler, fool neighbors
A trio of researchers at UC Davis has developed a method of using home-shopping standby cubic zirconia to cool hydrogen fuel cells by nearly 90 percent. Fuel cells typically run between 1,500 and 1,800 degrees Fahrenheit, but by adding a little fake ice to the mix, Zuhair Munir, Umberto Anselmi-Tamburini and Sangtae Kim have managed to run their cell between just 122 and 212 degrees. The system works because conduction take places in zirconia via "protonic movement" as opposed to "ionic mobility," which sounds quite fancy. No word on when we'll see these hit the market, but the team has already gotten their patent application in order -- only time will tell if cubic zirconia will actually seem valuable in the future.[Via Roland Piquepaille]
Hydrogen separator could power fuel cells from city gas
We've seen power hacks that allow hybrid vehicles to energize your domicile, but even that isn't enough to change how entire cities receive electricity. Now, however, the Japan Fine Ceramics Center (JFCC) has collaborated with Noritake Co. and a few other firms to develop "a high-performance hydrogen separation membrane made from ceramic materials" that can purportedly "attach directly to a gas pipeline to supply hydrogen for fuel cells using city gas as the source." Additionally, the the reaction to generate hydrogen can be carried out at a temperature of around "300-degrees lower than normal," and while current estimations are suggesting that cities won't be powered via this method until closer to 2020, there's always the option for a gigantic solar field to fill the void in the time being.

Microsoft: fuel cell rechargers for giveaways, not for Zunes
Well, it was a sweet dream while it lasted. Crushing our brief hopes of a fuel cell recharger for upcoming Zune models, a Microsoft spokesperson has come forward to clarify that the "small amount" of branded units purchased from Medis Technologies will be used as promotional giveaways at an upcoming event, and will not be joining the social any time soon. In fact, the company has no plans to sell fuel cell products at all, which pretty much rules out that hydrogen-powered laser mouse we've been fantasizing about. Oh well, we've been waiting for these magical power sources to get commercialized for so many years now, we can surely hold out a lot longer than this.[Via PMP Today]
Now microbes can create energy, too
We assume that, off in some lab, down in a petri dish, there's a serious grudge match going on. How else to explain the fact that, mere weeks after we first heard that scientists were training viruses to create electricity, there's an announcement that another lab-coated team is coaxing microbes to produce power as well? This time, the action is at Ghent University in Belgium, where researchers have found that certain microbes are able to break down organic matter in water and produce electricity in the process. One species in particular, Brevibacillus agri, turned out to be particularly adept at turning sludge into juice, and may someday form the basis of organic fuel cells. If the virii don't get there first, that is.
