The numbers and materials are indicative, but they show the principle …
- 1kg of water is boiled under the reduced pressure on the left side at a temperature of 308K (35oC/95oF).
- On the right side the condensed water’s temperature is lowered to 298K (25oC/77oF), i.e., 10 degrees Kelvin below the boiling point.
- There will be a significant 50kPa vapor pressure difference that powers the turbine. NOTE: Without the low cost (42kJ) lowering of the condensed liquid’s temperature to 10K below the boiling point temperatures, there would be a minimal pressure difference and a tiny engine efficiency. The more the already condensed liquid is cooled, the greater is the pressure difference at the different sides of the turbine.
- As the steam passes through the turbine, it loses energy.
- However, the turbine can never equalize the pressure difference. When the steam condenses into liquid, the water is still at the boiling point temperature and produces the corresponding vapor pressure. The exothermic heat of condensation (-2257kJ/kg) is released as the new intermolecular bonds are getting formed, as the steam condenses inside the turbine.
- Eventually, the steam condenses into a liquid, after losing all of its heat of vaporization (2257kJ/kg) to the turbine.
- After this, the right side only needs to transfer away 2% of the system’s added heat (4.18kJ/kg x 10K) degrees and return the liquid to the left side.
- The waste heat (2%) can be removed with a heat pump, so the system does not even need a cold substance for receiving the waste heat.

Bounty will be paid to the first who can show that this invention can’t replace most of the fossil fuels by 2044, because even with reasonable modifications…
- the device just doesn’t work OR
- its underlying theory is seriously wrong OR
- it will always be too expensive or unscaleable in comparison to existing energy alternatives
Quite frankly, I don’t think there is anything or anyone who can make this invention not to work. But please surprise me. I’d be super happy if someone could show that it doesn’t work, so that I would not need to be spending more time, energy or money for this invention. However, currently it’s my responsibility to check this thing out.
