ok.. so instead of using electricity i already have to power my angle grinder.... i'm going to use it for water electrolysis with great losses and then use that hydroxy gas created to feed an ICE powered generator to loose another 70%-80% and then power my angle grinder.... yup sounds logical... shut up and take my money !
That would be a good argument if he were using mains to generate the hydrogen, but I think you missed that it's meant to be a portable generator, hence self-contained.
Note that I am not rooting for it. Just pointing out that calling it bollocks for a plainly wrong and easily refuted reason is just playing into their hands.
where did i mention mains
he starts the electrolysis (apparently from the generator's battery) and then starts the generator... he's loosing energy right there - the gas he makes will release less energy after burning than the energy input from the battery for the electrolysis and the combustion engine powered generator will convert only 20-30% of the energy in the gas into electrical energy.
so it's impossible to make it self sustained , the energy comes from the battery.. no discussion here.. law of energy conservation is on my side
so in fact you would be far better powering the angle grinder from inverter connected to starting battery of that generator.
the whole thing is big scam - the magioc HH+ ingredient will be just potassium hydroxide which is commonly used in water electrolysis (table salt would lead to chlorine gas production).
another dead giveaway is the video itself... too much emphasis on simple mechanical tasks (drilling, cutting, tightening nuts...etc..) simple tasks means simple people can easily relate to it and easily fall for the scam.
