[Open Source Energy] Geothermal
|
You can tap in to the earth’s energy almost anywhere on earth. The best known geothermal energy sources are steam and heat that lie close to the surface in the form of volcanism or a geological hot spot. The earth’s center, or core, is molten metal , or so say the science gurus, and I have no reason to doubt them. Residues and out venting of this heat is what drives plate tectonics, volcanoes ,earthquakes and heat that can be used by us in the form of steam to drive turbines or heat exchanger.
The earth is a constant temp in most parts of the world. Some passive technologies take advantage of this fact and use the earth for a passive heater or air cooler. The law of thermodynamics isn’t violated because you are exchanging heat for cool or vice versa.
