Not read the link but its very easy to split water using an arc welder.

Cathode, anode, water, and electrcity = hydrogen and oxygen

Burn one- it re-combines to get water.

Make the braking system KERS

Make the ignition system from solar powered, job done

It wasn't a serious post, just a stupid video

In your example, where does the electricity come from for the first step?

Hmmm... I admire the plan, but if you've got solar cells, why not just use the electricity from that, or store it in a battery for use later?

Copy and paste from elsewhere so I don't get figures mixed up...

'Electrolysis is about 70% efficient (30% of the energy used is wasted). This is much less efficient than batteries.

Fuel cells are then only 40% to 60% efficient and waste heat is generated. If the waste heat is used as well, overall efficiency at point of generation can be greater, but the theoretical maximum is 85%. At minimum, 15% of stored electricity is thrown away. In reality, no automotive fuel cell captures the waste heat, so 40% to 60% of the stored electricity is thrown away. If the hydrogen is burned in a Carnot or steam cycle, then efficiency is even lower than via a fuel cell, closer to gasoline where efficiency is in the range of 20%.'
