LOL! There is no "hydrogen energy" in water.
Sure there is, just like your car's exhaust contains energy that can be released after you simply convert it back to fuel + oxygen. We are getting very efficient in that process, and as soon as we figure it out, we'll be energy independent. All I need is a government grant. (Insert sarcasm tag as required...)
what...hydrogen gas is not made from splitting the water molecules? You need to know some basics before you make a dope of yourself.
Maybe not in water, but take your fat wife with you and you can do this!

Eco-boat powered by human fat attempts round the world speed record
The fastest eco boat on the planet will attempt to break the round the world speed record using fuel made from human fat.
Pete Bethune, the New Zealand skipper of Earthrace, said the attempt to circumnavigate the globe would begin from Valencia in Spain on March 1 next year.
Bethune and his wife mortgaged their house and sold everything they own to help make the project happen, while continuing to seek support from sponsors.
