Reducing fuel burn

This is not my idea. It belongs to Prof Zimmerman (w)
You take the spent steam from a steam turbine, and pass it down a double helix. It emerges at the base as hot liquid water.
Up the other helix, you pass low pressure gas – this is how your fridge works. When you pressurize the gas, you return 8%% of the heat to the boiler room above the boiling point of water.
In a fridge this is how your fridge creates cold from warm air in the kitchen! Here we reverse the cycle, to condense the steam, and return the bulk of the heat to the boiler.
So we reduce fossil fuels burn by a factor of 8! Though we do use 4% of the generated power to circulate the gas. We have no cooling tower – no massive stack of steam taking heat from the plant.
So we reduce fossil fuels burn by a factor of 8. And so we reduce the Global Warming gases massively, as power generation accounts for 40% of CO2 output today.
We can use this cycle to replace the throwing away of waste heat from processes!
This was devised at Sheffield University in 2001. Why has the world not heard about it? Why did I not get my PhD?
