Mr Meyer died approximately 15 miles from where I live.

Everyone in the area was THRILLED about the research facility he had secured funding for. If memory serves me right, several news channels had interviewed him, and taken rides in his water car (With rave reviews).

It still gives me chills when I drive by the cracker barrel off of 71/stringtown, knowing what happened there.

I can't manage to think why some people would not at least give this a chance, ohh bla bla it's not working the same amound you put it you get out and so on.

Acording to some people we would not have nuclear energy because it would be impossible.It was the same problem with nuclear fussion.At the begining stage of nuclear fussion experiments at the time results pointed out that less energy came out from what was put in until everything changed, then more energy came out than what was put in.So you put in something and you get more than what was in the bag in the first place, it's possible, get over it.

Electrolisis is ineficient in standard form, but change that in to another form and something else happens.

Atoms can break apart at very low energy levels, as in water molecules.
Sometimes in rare cases molecules in the water will break apart by them selfs.Standart electrolisis is ineficiant, but what if everything is aplied to a specific frequency, the frequency where everything breaks up easy and becomes free as in hidrogen and oxigen.A power suply plus a pulse circuit tuned to a frequency can do the job.High energy diodes that transmit energy in to the water at a specific frequency cause the water molecules to disasociate at lower energy levels setting the two elements free.
There is a frequency where everything will dance by pulse to give it only the amount it needs.

From what I saw in the videos of stans water car, , the hydrogen generator was only one part of a larger system. The engine in the car ran on hydrogen and was injected with water. Heat from combustion vaporized the water providing more power as in a steam engine. I can't say that could tip the scales in terms of conservation but the internal combustion engine leaves a lot of room for improvement. Cars are only 20 or 30% efficient and we buy them by the millions pump thousands of dollars in fuel into them. Maybe he did find a way to get it to work,even if it was marginal, it would still be a great accomplishment.

I noticed a Tesla ignition coil on some of these run on water cars and with a
hydrogen rich combustion chamber there might be a no oxygen pressure
release of combustion in the ordinary oxygen combination with carbon and
thus the water product.
The Tesla ignition coil was taken out of the early Model T by Henry Ford
himself as being too powerful. Sure we wouldn't want anything too powerful
to give us good gas mileage.
ED: I haven't checked on the Papp Helium Engine over on youtube lately
but do believe there is no radiator, a self cooling reaction motor.
