So, how do they take the hydrogen from the water scepti?
By electrolysis.
So they take electricity, split water, then use the hydrogen to create electricity? Do you not see the problem with that? Assuming zero loss between each step, they are taking something running it through a process and coming back out with the same something. Now when you factor in that electrolysis creates heat, and is not nearly 100% efficient, you are getting LESS useful energy out than you are putting in. Makes no sense. Why not just take the electricity and send it to the grid?
sceptimatic seriously needs to read up on the First and Second Laws of thermodynamics. I'm repeatedly surprised that for someone who's proved the earth is flat (with a complex and expensive laser/flat ice sheet experiment) plus invented many things we now buy in our stores he has so little knowledge of physics. Even stuff that high school kids understand.
Possibly his father—who's a world-renowned scientist—never gave the young
sceptimatic much of his time? One would think though as he's extremely wealthy, that
sceptimatic would invest in a little more time and money into tertiary education. He obviously has no need to work full time, as he makes numerous holiday trips to North Korea throughout the year, and, unlike other Westerners, without any special dispensation from the NK government.
And by the way
sceptimatic, the high cost/low efficiency of water electrolysis is the main reason we're not running our cars on hydrogen. Electrolysis is only around 60% efficient, so that 1kg of hydrogen (specific energy = 40 kWh/kg) requires 65kWh of electricity to produce. This hydrogen then works at to around three times the price of natural gas as a fuel.
