Horizon Fuel Cell Technologies have launched the the Bio Energy Discovery Kit, a product that they are calling "the fuel cell industry?s first direct ethanol product." The kit directly converts alcohol into electricity and can run non-stop for days on end. The purpose of the kit is to introduce fuel cell technology to students, scientists, teachers and engineers using a simple gadget that is easy to understand.

However, they claim that the kit could be the first step towards replacing conventional batteries in portable devices like iPods or mobile phone chargers. I don't know how practical a commercial application would be, or whether or not I would be willing to give up a single drop of my precious vodka, but you can pick up the kit now for $99.
