The important question here is how much energy is required to start the electrolytic reaction as this is what seems to be happening.
Secondly, this may be a much cheaper way to extract hydrogen instead of the conventional method of using expensive platinum plates from water or from existing hydrocarbon fuels (natural gas, etc) since those methods produces a lot of CO2 by product waste.
You don’t need expensive plates to make hydrogen from water, stainless steel plates will do. You don’t need large amounts of electricity either, 1.5 volts @ 2- 3 amps will create a good flow of hydrogen gas and oxygen. Salt helps improve conductivity.
Many have tried all sorts of variations and materials to improve the rate of gas generation to achieve “unity”, but the best they can do falls far short of that.
Google around, you’ll find all sorts of basement experimenters trying all sorts of silly things in the attempt to save the planet and stop global warming (none of them have more than a grade 8 education either it seems).
Some of them are quite funny.
