Microbial Fuel Cells: Potty of gold.

  > ...it takes almost as much energy to produce the hydrogen in the first place as the hydrogen will later provide when used as fuel. Sweet! I'm totally building a perpetual motion device based on electrolysis of water. Edit: On a serious note, this article is crap science reporting. Hydrogen is not an energy source, it's an energy storage mechanism. There is no freely available hydrogen, we need to produce it using existing energy sources such as hydrocarbons or solar or wind power. Not only that, it's not even a great storage mechanism. Somewhere around 50% of the energy put into the electrolysis process is wasted.
