That second video you posted isnt a stanley mayer device.... thats something different. However, that system is very cool too. It recycles exhaust gas in a really simple process utilizing similar principles to the stanley mayer. You can burn any fuel and there are no emissions.... seems unbeleivable but read more about it and you'll be amazed.
Ironic that you posted this.... Ive been researching this for a long ass time now. I am in the middle of building my own hydrogen synthesizer just like Mayer made... theres an open source forum going on about the topic.
Once i get the system running and working well, im going to install it in my old chevy pickup with a carbed 350 and get it to run. It shouldnt be very difficult to do. The HHO gas that is extracted from the water is already in a perfect stoichiometric ratio. Making it work on a carb'd engine will be the easiest. And the best part.... the exhaust turns back into water!!! The exhaust can be recycled back into the water reservior and REUSED! Its ALMOST perpetual motion....however there still is friction involved. Lets not forget that hydrogen, when ignited, emits a charge that is 2.5 times MORE POWERFUL than gasoline.... So cleaner burning, NO EMISSIONS WHAT SO EVER, FREE FUEL, AND MORE POWER...... hell if i have to spend 10,000$ to get it to work, its definetly worth it.
I tell ya what... Stanley Mayer was murdered.... along with a few other followers. Its a DAMN SHAME. There was an interview where a bunch of arabs offered him $1 billion to basically stop his experiments. He refused to do that because he knew this would change the world as we know it.
Well, now its open source.... there are already a couple dozen people that have recreated his rapid hyrogen making machine... theres a bunch of videos on youtube. This could potentially start world war 3 if you think about it. The oil companies own the world right now. When this technology starts becoming more mainstreamed, we will have no need to buy tons of oil anymore. The oil companies will literally go bankrupt.
A couple nice websites that ive been checking out...
