Well I am not sure who came up with the idea but thank goodness for it. With the gas prices going through the roof and the economy getting worse it is such a blessing that someone figured out how to run your car on water. My brother has a tour business and he pays some ridiculous amount of money just filling up his jeeps every month. He is going to get them all converted to run one water so he can save that money and put it to better use. I can’t wait to get mine converted over. What a great idea!
