He didn't even know what focus fusion is... I wonder if he knows about reverse configuration or the polywell.

The Carbon Credit system has been around for a while... circulating. It's weird to think of a carbon credit as a STOCK Option though. I mean, can you picture that kind of world where carbon credits are traded like stocks? It's either really good or really bad...

Here's what you do: take that electricity and use is to separate hydrogen from oxygen in water. Ta Da! That's how you don't lose the electricity.

Practical, cost-effective electrolysis of water is ~50-70% efficient.

Practical, cost-effective hydrogen fuel cells don't exist, but the ones that do exist are about 40% efficient. Compressors are rather inefficient and will consume energy equivalent to ~10-20% of the energy content of the hydrogen gas depending on pressure. Hydrogen is about the leakiest substance in the world, there are non-negligible losses here as well. The theoretical upper boundary of hydrogen fuel cell efficiency is 83%.

You've overlooked a few things, like how much it costs to do that.
