You asked for the injectors. Stan Meyer's water fuel injectors, photographed in 2008: one stamped WFC 422 DA, one opened up to show the probe inside. In 1990 he held one up and said the whole lab came down to this. Then his own drawings: T304 stainless probe, a 14 mm spark-plug thread, and the cone

What was shown

You asked for the injectors. Stan Meyer's water fuel injectors, photographed in 2008: one stamped WFC 422 DA, one opened up to show the probe inside. In 1990 he held one up and said the whole lab came down to this. Then his own drawings: T304 stainless probe, a 14 mm spark-plug thread, and the cone where the water fires. Every part, every dimension, on the site.

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.
