We have a 50x1cm steam plasma tube at 4 atmospheres. Once started with a pulse of power at 2,000V, it runs unpowered, using 5x10-13 of regular water a year – for heavy motoring.
We drive a fan, and heat air to 380oC. We pass this over a thermoelectric generator – read Automotive Thermoelectric Generators and HVAC
We get at 144kW of power – a helicopter only needs 45kW: thinks, fly between cities in you car.
So no large storage batteries – massive weight saving. No expensive petrol of diesel: so no emissions – though the world has been cooling 21 years. Nuclear made up Global Warming.
We use very, very little regular water. And the science of the fluorescent light.
