At 24min 06seconds Dr. Wysession mentioned that it is possible to combine steam turbine power generation with isobutane power generation, in geothermal power generation.
This could be applied to solar steam power production to extract additional energy from the water/steam mixture in the exhaust. After the steam passes through the power generation turbine what is left is a mixture of steam and water.
This steam/water mixture is usually at a higher temperature than its surroundings, which implies that it is possible to extract additional energy from this exhaust. One way would be to employ smaller power generation turbines that can operate at the lower pressures and temperatures of the steam/water mix. There may be some engineering issues since both steam and water are present.
Another option is to pass this steam/water mix through a heat exchanger where the heat is transferred to a liquid with a lower boiling temperature like isobutane. Then the isobutane is used to run a power generation turbine.
Yet another idea involves the working fluid of a solar steam plant. Usually this "working fluid" passes through pipes of solar steam plant located at the foci of the mirror concentrators. This fluid is used to heat water into steam, through a heat exchanger, and then the steam passes through a turbine to generate electricity.
The temperature of the fluid that exits the heat exchanger is often higher than that of the surroundings, so this fluid can be passed through a second heat exchanger to heat a fluid with boiling point lower than that of water and then this high pressure vapor can be passed through another turbine to extract even more power.
By employing combined power generation it may be possible to raise the efficiencies of solar steam power generation. In fact the ideas above can be used with almost any method of power generation since most industrial scale power generation methods use steam turbines to generate electricity.
I've got more ideas for making things more efficient and more effective. So keep your device on this bloggo.
