Violating the second law of thermodynamics is entirely impossible.
Always has been. Always will be.
Entirely.
Being a really really old person..I often wonder about what happened to something I actually saw on BBC TV many years ago.
A guy named Ferguson (he owned the Massey Ferguson tractor company) was showing off a car he had invented. The vehicle was powered by oil or similar fluid under pressure in a tank under the hood. Two hoses led to each wheel and the fluid was forced against an enclosed fan on each wheel. Then it was returned to the holding tank..when under braking the fluid reversed the jets and stopped the car.
There was a minimum of oil loss to the tank and it was just topped up every few months.
I was just a slip of a lad at the time..but I can still see the driver aiming for a brick wall and stopping easily.
You might think that this system would have had massive publicity..but I never heard anything else about it after that news flash. I would be interested to know if anyone else has ever heard of this?
What a tremendous thing if it worked!! No more engines or gas to worry about..oil companies going tits up all over the place!!
