Sorry cheif, as much as we hate those mean big oil companies, we are still bound by the laws of thermodynamics.
big oil companines are investing quite a lot of money on alternative fuels.

More than anybody else in fact... by leaps and bounds even.
it doesn't hurt when they have more money than almost anyone else to begin with. if there were unlimited supplies of oil in america or other pro-western areas, i don't think they would be doing this research simply for the good of the environment. yes, i am cynical.
This story has a lot of appeal. Average joe triumphs over dogmatic scientists and corporate concerns to solve one the biggest problems facing the world, with just a little elbow grease and some good old fashioned 'merican determination. We want to belive this is possible.
Dr. Robert L. Park Proffesor of Physics, from my alma mater, UofM in College Park:
"In the early '70s, an inventor named Sam Leach built an automobile that he claimed used only water as a fuel. Leach explained that electrolysis was used to separate the water into hydrogen and oxygen. The hydrogen was then burned as a fuel. In the burnin g of hydrogen, water is the only combustion product. Leach's water-powered car was a classic violation of the First Law of Thermodynamics: you start with water and you end up with water plus heat. Scientists pointed out that it would take more energy to decompose the water than it is possible to recover by burning the hydrogen. Ordinarily th at would be true, Leach acknowledged, but he claimed to have discovered a new catalyst that makes the electrolysis process much more efficient. The wonderful thing about the laws of thermodynamics, however, is that you can set limits on the outcome without knowing the details of the process. It's is clear from the First Law that no matter how efficient the electrolysis, there will still be a net energy loss.
Nevertheless, after Leach drove his water-powered car across the United States, investors who didn't understand, or didn't believe, the First Law of Thermodynamics, clamored for a share of the invention. No one else was allowed to test the car, lest they steal the secret catalyst. The President of Budget-Rent-A-Car sank $2 million in the idea, envisioning a fleet of cars that could be fueled with a garden hose. And what of Sam Leach? He retired a wealthy man, without ever having revealed his secret catalyst."
