"Notice this revolutionises money in a way that invalidates all arguments of cost..."

You can never invalidate the argument of cost. And one often hits the limits imposed by physics and chemistry.

Does it need more work? Definitely. But again, I'd have to question just how much improvement "cranking the handles" is going to have on a seven-meter wide system that currently fails to produce even half the power needed for a singe home in a day.

Even if you managed to double (or quadruple) production, you still have to compress, store, and ship the stuff, all of which requires power and which eats into efficiencies even further.

And it still suffers from the solar issue, in that production only occurs during the daytime when the sun is actually shining.

Bottom line is where is it best to allocate resources?

I still think if you want "green" hydrogen you need to follow the Japanese nuclear experiment, which utilizes waste heat to generate hydrogen as a byproduct.
