Rohm 5Wh hydrogen fuel cells power up smartphones, ready for the trash after one charge
Rohm's hydrogen fuel cells are meant to power smartphones and other mobile devices, but unlike other juicing-up solutions, the cells are only good for one charge. Rohm says disposable fuel cells can be made smaller and lighter than their multi-use counterparts, and as the only byproduct is hydrogen, the company is touting the cells' eco-friendliness. The system generates electricity by using hydrogen that's created by the reaction of a metal material and water. While the device we saw here at CEATEC is a prototype, Rohm may offer its recharging system as both a smartphone case and a USB-attachable juicepack. Each offers 5Wh and can fully charge a handset once. There's also a 200W power generator, which certainly stretches the meaning of portable but can keep a laptop, LCD TV and a peripheral or two going for three to four hours. Rohm says its fuel cells will see a commercial release some time in 2013; for now you can get a sneak peek in our hands-on gallery below. Zach Honig contributed to this report.
Gordon Murray reveals new Batmobile, Dark Knight gets serious about reducing carbon footprint
So you've finished building your Batman Forever-style Batmobile, your Tumbler's up on blocks in the front yard, and you're itching for a new project. It's not too early to start planning a DIY version of Gordon Murray's newly unveiled Bat-ride (part of the Batman Live World Arena Tour). The designer drew on his experience with the McLaren F1 for his new concept car, which includes a healthy dose of imagineering: there's a carbon-fiber body that "breathes," as well as LED-lit "virtual wheels." We're not sure how carbon fiber breathes or what virtual wheels are, but as Murray explains in the video below, they're based on Formula One materials as he imagines them 15-20 years from now. He also envisions a greener Dark Knight, whose ride runs on hydrogen fuel cells and lithium-ion batteries -- no longer will the caped crusader suffer a guilty conscience due to his excessive carbon dioxide emissions.
