fun fact: geothermal energy is mostly nuclear energy from radioactive decay of radioactive elements on the earth<br><br><br><br>So you can say you are swimming in a Nuclear Power Plant Wastewater,(reply>), @Apalala the heat generated by the Earth is pressure and the decay of nuclear isotopes in the mantle. So it is kinda like a large RTG reactor.,(reply>), Geothermal energy comes from volcanic activity, not from radioactive decay.,(reply>), Well not really because the plant isn't designed to directly deal with nuclear substances. But I get what you mean.,(reply>), @whophd you need more LFTR in your life,(reply>), @Leonardo Avellar Is that a challenge?
