A potential solution to rising gas prices

There could be a relatively simple answer to the problem of rising gas prices. Apparently there is a way to supplement gas powered cars using a fuel known as browns gas. As I understand it browns gas is basically hydrogen and is created by using water and electricity. The reaction for anyone interested is 2H2O + electricity = 2H + 2O. The browns gas is then mixed with the gasoline in your engine to greatly improve efficiency. The electricity apparently can come from the battery of your car. I don't understand all the technical details but it has gotten me very interested and should many others. Apparently any car can be converted to burn both fuels. If everyone had their vehicle converted to be able to burn browns gas along with gasoline the resulting increase in fuel efficiency would mean less demand on oil and the price of oil and gasoline would drop. And since converted vehicles would also burn less gasoline the savings everyones fuel costs would plummet. An additional benefit would be cleaner burning cars since browns gas only produces water as a product of combustion. I'm not sure about the costs of actually having cars converted. To me the environmental benefits along with the long term savings would be worth it even if it were expensive to convert my own car.
