I found recently the existence of Geothermic Energy and i didn’t really understand It.
There are zones where the underground is so hot we can get energy (Electricity) from it. How?
I read that One of the first to do It was in Italy, in the 1904 or something, and i don’t understand how could they build something without…well die. If the heat is so High wouldnt people be hurt? How could they build something like that? I guess that now is more easy but at that time how was that even possible?

Ok so power plant basics.
Coal, Oil, Nuclear, Wood, etc.
Get bunch of stuff HOT. Use heat to boil water. Use steam to spin turbine (windmill). Turbine spins generators.
Geothermal just replaces the pile of burning stuff with the Earth’s core (well Nuclear isn’t “burning” but close enough).
Hydro and Wind cut out the heat and use water or air to spin the turbine.
Natural gas is a bit more complicated, because in a combined plant you basically have a big jet engine spinning the turbine and then use the exhaust to spin more turbines. There might be a steam loop in there somewhere too.
Solar panels are the only source that produces electricity directly.
