My ground heat source works for the seas. The seas are link massive heat collectors, that draw in energy from the sun and the land. Each day 26 Terrawatts of power. The problems has been how to get at it.
The science was worked out in the 1950s – the heat pump. We circulate low pressure gas, through a huge heat exchange on the bottom of the sea.
It enters at -20oC, and leaves at 18oC – higher for hot countries. We double the pressure of the gas, and suddenly it is at 228oC. So we boil off water. And drive a steam cycle.
We generate 20 MW of 0 carbon, free energy. We then repeat the trick on the exit steam, so we produce water at 98oC, and get back 92% of our system energy – the steam turbine heats the steam up by 10oC, and emits X-rays as the turbine and boiler room do Molecular Nuclear Fusion.
So we get 20 MW of energy – the grid will par 120 trillion for over the year. By using a resource which has been largely unused since the 18th century.
A decent sized lake will act in place of the sea. And we cool the water down by just 2oC. Even in winter. No Fossil Fuels burn. And no hyper toxic nuclear fission from U.
So if you live by the seas, you are sitting next to an endless source of low grade heat. Using 1st year undergraduate engineering, we can turn into MW of free, carbon 0 power.
Britain is surrounded by an inexhaustible source of free power. And man's energy use is so tiny, nature will not even notice.
If we want to get serious, we build a 100 MW plant, 20m off shore. And we send in the power through an under water cable, and the national grid pay us 100 billion a year. Cost of building the plant – under 50,000 UK pounds.
It makes a new nuclear plant at 18 billion look stupid. It would generate the most toxic waste known to man. And has a high chance of spraying radioactive waste over the UK, within 25 years.
Making Britain uninhabitable.
And sea power is carbon neutral! It cools the hot lands – and that is it! Massive income, and no waste. Using a natural energy supply, that is totally wasted today. Using 1950s science.
