You’ve heard Ethan many times speak and write of geothermal energy as the only clean, renewable, baseload power source. This is an excellent video demonstrating the concepts.

Transcript of the video:

Geothermal energy gives us a steady supply of electrical power, with minimal environmental impact!

Here is the basic process.

Water, in underground reservoirs, is heated to high temperatures by magma.

Production wells, drilled up to 10,000 feet below the earth’s surface, tap into this hot fluid.

Under its own pressure, the fluid flows through these wells toward the surface.

As it travels, the pressure lessens, causing a small amount to become steam.

Together, the hot fluid and steam move through a surface pipeline to a wellhead separator where the pressure is reduced.

Here, most of the fluid vaporizes and “flashes” into high-pressure steam.

Any fluid not flashed into steam moves to a standard-pressure crystallizer – to produce standard-pressure steam.

Remaining fluid is then flashed at a lower pressure to create low-pressure steam.

All steam created in the plant is sent to a turbine on site.

The force of the steam spins the turbine’s blades – which turns a shaft connected to an electrical generator.

An electrical charge is created, and directed to a transformer where the voltage is increased and sent down power lines.

Any fluids not flashed into steam return to the underground reservoir where, in time, they will be reheated and re-used.

Geothermal energy. A simple, clean and renewable energy source!
