Alcohol-powered Fuel Cells

prostoalex writes "Researchers have developed a fuel cell that can be recharged with few milliliters of alcohol. MIT's Tech Review quotes the researchers claiming that those 'cells could eventually be used as a replacement for any rechargeable power source, including laptop and PDA batteries'. I suppose the scientists still have to explain all those bills from liquour store that say 'research material' on them."

    Finally! Now I can leave my notebook's airline power adapter at home and just use those tiny bottles of cheap vodka. A measly $5 per recharge sounds fine to me.

    Seriously, though. This could be good news for the cereal grain industry. Corn is abundant, cheap and easy to ferment. I wonder how the efficienccy of this technique will compare to that of regular batteries and more "traditional" hydrogen fuel cells?

    1) What kind of alcohol?

    2) What "poisons" this fuel cell? Will it survive a bit of water?

    3) What are the by-products of power generation? Can it be used to store energy too?

    4) How many watts per kg or liter?

    Sheesh. And it's only been tested for a few months. I'll bet there are at least a few unknowns yet to be discovered. Nontheless, the concept is interesting. The question is whether this can become a practical commercial device. You can't even begin to guess with shoddy reporting like this...
