Build your own Water-Fuelled engine

irregardless of the heat

Energy grows and is 'magnified'

This is how it spreads many blocks away. This is how rock transforms into a rubbery and undulating motion. This is the secret of the earthquake

Your friend invented that car in the 1980s? Why isn't it being produced yet? The news story (from the 80s) says it would go into production in just a couple of years.

Why haven't you built one yet if this guy is your friend? Didn't he give you the top secret plans?

There was a car produced in the 1980's which ran using only water. The reason it was never sold?
There is two good reasons;

I have built one prototype water powered apparatus it runs on nothing but water, shock waves, and stored kinetic energy.

In 1996, Meyer was sued by two investors to whom he had sold dealerships, offering the right to do business in Water Fuel Cell technology. His car was due to be examined by the expert witness Michael Laughton, Professor of Electrical Engineering at Queen Mary, University of London and Fellow of the Royal Academy of Engineering. However, Meyer made what Professor Laughton considered a "lame excuse" on the days of examination and did not allow the test to proceed.[3] According to Meyer, the technology was patent pending and under investigation by the patent office, the Department of Energy and the military.[citation needed] His "water fuel cell" was later examined by three expert witnesses in court who found that there "was nothing revolutionary about the cell at all and that it was simply using conventional electrolysis." The court found Meyer had committed "gross and egregious fraud" and ordered him to repay the two investors their $25,000.[3]
