|PCT/IB2011/002675||MOSKAL, Denys||MOSKAL, Denys|
Method of production work from thermal exchanging in counter- current streams is realised by recuperation of overflow internal energy from working mass. Inside countercurrent exchanger the overflow internal energy from the heated in a previous cycle working mass, will be transferred into the cool working mass for next cycle. An example of the heat engine, built on this method, includes two cylinders which are connected through countercurrent exchanger E. Under piston PC1 in cylinder C1 there is working mass in liquid phase. In the right cylinder C2 there is working mass in gas phase under piston PC2. The work W1xpended in C1 when the force acts on piston PC1 and liquid phase is moving from C1 into C2 through E, but gas phase is moving towards from C2 into C1. Overflow internal energy AU from gas phase transferred into internal energy of liquid phase. As result piston PC2 is moving up and producing positive work W2=ΔU>W1.

The pumped-storage power plant comprises a pressure storing system with at least two pressure containers which can be filled with water and which form a common pressure storage volume; a water outlet for discharging water from the pressure storing system directly into the surrounding sea against the hydrostatic water pressure (PT) corresponding to the water depth (T); a pump which is arranged at the water outlet for pumping water out of the pressure storing system into the surroundings sea, said pump converting electric energy into corresponding potential energy of the displaced water column while the water is being pumped out against the hydrostatic water pressure (PT) of the surroundings sea; a water inlet for introducing water directly from the surrounding sea into the pressure storing system with the hydrostatic water pressure (PT) corresponding to the water depth; a common generator arranged at the water inlet, said common generator converting the potential energy of the previously displaced water column back into electric energy while the water is being introduced with the hydrostatic water pressure (PT) at the water depth (T); and electric lines for transmitting the electric energy from the water surface to the underwater pumped-storage power plant and back. The pressure containers are pressure-resistant such that said pressure containers can be pumped empty by means of the pump in a dimensionally-stable manner against the hydrostatic water pressure (PT) at the sea bed.
