We have the technology to do a lot of things and one of these is to tap the earths energy. This is exactly what we do when we decide to use geothermal which happens to be a green energy source.
Geothermal energy is energy obtained by tapping heat from the earth itself. This comes from magma and the radioactive decay of uranium, thorium, and potassium.
The downside to geothermal energy is the fact that it is expensive to build. On the other hand, because the earth’s crust continuously decays replenishing the heat, it is still a renewable source of energy.
There are three types of geothermal plants around. These are namely dry steam, flash, and binary.
Dry steam plants take steam out of fractures in the ground and use it to directly drive a turbine that spins a generator.
Flash plants take on water at temperatures over 200 C, out of the ground, and allows it to boil as it rises to the surface then separates the steam phase in steam/water separators which runs the steam through a turbine to generate electricity.
Last, you have binary plants. Here, hot water flows through heat exchangers and that boiling organic fluid is what...
