"Fill it up with water": what Stan Meyer actually meant

"You fill it up with water, turn the ignition on, and run down the road." Everyone clips that line. Here's the middle step both sides skip, in Stan Meyer's own words.

About the voices. The narrator is NeuralStan, an AI voice the archive uses for its made films. Where you hear Stan Meyer, it is Stan: every word of his is cut from an original recording, and nothing he says was synthesised.

Stan Meyer (original recording) · You fill it up with water, turn the ignition on, start it, and run down the road.
NeuralStan (AI narrator) · That's the clip everyone shares. Half the internet says water can't burn, so it's a scam. The other half thinks the tank is full of fuel. Both skipped the middle.
NeuralStan (AI narrator) · Water isn't the fuel. It's where the fuel is stored. His electronics split it into hydrogen and oxygen at the engine, only as fast as the engine burns it, and it goes out the exhaust as water again.
NeuralStan (AI narrator) · In his final design, it happened inside the injector itself.
Stan Meyer (original recording) · So the water is only converted into thermal explosive energy as it enters the injector.
NeuralStan (AI narrator) · And what comes out the back?
Stan Meyer (original recording) · On a cold day, as the superheated steam comes out of the exhaust, it would just simply cool down, and the roadway would be just a little bit of moisture.
NeuralStan (AI narrator) · Water in, water out. The real argument is how little power his cell needed to split it. Argue about that.
