One for our resident chemists to theorise over.
Theory
Electrolysis used to split water into HHO gas which is highly flammible. Burn this gas along with regular fuel and get much better MPG. (The mixture with regular fuel negates the need for expensive engine conversion.) So with a litre of water you can get 1000's miles worth of energy by splitting it.
Reality:
Surely the amount of electricity used to "split the water" into this magic gas will be greater than the energy released when this gas is burned? The by product of burning HHO is water - very enviro fiendly.
If it really is this easy/safe/simple why don't car makers do this already? (Is there an oil company conspiracy?
)
Why?:
I saw a "spend $50-$100 on a book site" with instructions on how to make this work. I am a little sceptical thinking about the laws of conservation of energy.
