My Dad used to install upgrades to motors to run on tap water. However, the engines wouldn't last long - they would rust out... If you wanted to get this done, you would definitely need to put ceramic on your engine to avoid this.
The concept is this:
H2O - electricity separates the hydrogen and oxygen - the hydrogen is used as fuel and the oxygen is released as a by-product.
Pretty cool - however, you won't be seeing anywhere near the 230HP my engine currently produces (stock + 15HP gain from Cat-Back System).
