New Fuel Cell System 'Generates Electricity with Only Water,

… Air’

Now that sounds interesting, if it works as claimed:

[quote]Genepax Co Ltd explained the technologies used in its new fuel cell system “Water Energy System (WES),” which uses water as a fuel and does not emit CO2.

The system can generate power just by supplying water and air to the fuel and air electrodes, respectively, the company said at the press conference, which took place June 12, 2008, at the Osaka Assembly Hall.[/quote]

Click me

fascinating. now, where’s the electricity come from to pump up the system? is THAT co2 free?

and how does one recharge the system when the metal reactant is all used up?
