We have a 10x1cm steam plasma tube at 4 atmospheres. It releases 24 kW. So it is going to boil off water in 4 seconds.
We feed this into a cylinder driving the outside of a steam turbine. We generate 300 kW: a small helicopter only needs 45 kW.
We use some of this power to drive a Carnot cycle. We pass the steam down one helix of a heat exchanger, and at the base it is liquid water at 90oC. This provides the low pressure end for the steam cycle.
The gas passes up the other leg, being heated from 90oC to 250oC.
We use the high pressure end to superheat the steam from 120oC to a more useful 240oC. No mistake, the steam heats up by 10oC as it passes through the turbine, and does Molecular Nuclear Fusion.
So the steam plasma tube also does Molecular Nuclear Fusion – the infinite power source of nature.
So the chair is enclosed, has a seat belt and luggage space – OK, a big chair, The steam plasma tube and Carnot system and generator fit below the seat.
No Fossil Fuels burn. No CO2 – but plants gobble up all extra CO2 to leave a pre-industrial 2 parts per million average CO2 in the global air. 400Ppm – that is nuclear fiction – biological rubbish.
So we have personal point to point transport: OK, we need radar and computer systems to drive the craft safely. Google have got it all worked out for their driver-less taxis.
Welcome to the future – more advance than Back to the Future ever dreamt. No doubt Ford is working on this idea.
