This crucial number here is the strong atomic force. We need turbulence in the steam to causes the exposed hydrogen ions to fuse.
The valency electron is displaced towards the oxygen ion. This causes waterfalls over 1 meters high to give off X-rays, as they do Molecular Nuclear Fusion
1 H2O+Tu ->He2++O2-+X-ray+E2+L
Now the X-ray, light and He production can only result from nuclear fusion or fission – and we have no source of fission.
We recycle the heat by cooling the steam on the cold end of a Carnot heat pump, which return 85% of the heat to the boiler room.
That 15% id the problem – and starting the cycle. Unless we design in turbulence, we are still short of 5% of the system heat.
My favourite answer is a steam plasma tube. Which once started, will continue to liberate heat. And the water we burn is 1cc per year = matter is such a dense form of heat.
And the tube will produce 5.l8 MW for a 1m meter plasma. This is massive heat! So 4 will run a 100 MW power station! And only consume a pulse of electricity at 2,000 V to initiate.
No CO2 – or hyper toxic radiative waste. Somebody tell Barak O'bama.
