These myths have been around forever. Note even in the show there that along the way it's using house current - perhaps made by a coal fired plant to make/keep batteries charged to make hydrogen to get energy which would have been twice as much bang for the buck to use the electricity directly.
It equates to using hydro-electric power to pump water back up a dam to run thru turbines again and again - it just don't fly folks!
I'll be dead and gone but the real magic of energy is to capture what would have been or is wasted anyway for use later.
It was Isaac Newton's work that says it all so well - long before so much as a ball point pen was invented!
