We have a 25x1cm steam plasma tube at 4 atmospheres. We we give a pulse of 2,000V, it springs into life, releasing 580kW of heat from 7x10-20cc of regular water a year. We top up the steam, by a spring loaded hypodermis needle.
We use this to drive a little turbine. We can easily get 50kW of power – enough to drive a small helicopter. So no visits to a service station ever. No Fossil Fuels burn, and no petrol or diesel.
