Rather than a cooking pot that heats up by your computer over USB, it's actually a pot that uses energy that would've otherwise been wasted, to charge up any USB device. An alternative to the solar-powered charger, you could say.
It's just gone on sale in Japan for the equivalent of $280, and can apparently charge iPhones in under five hours. While I'm rather dubious of dangling a USB cord over an open fire, apparently it's safe to use with any fire or stove, also. [TES via Asiajin via CrunchGear]
