Geothermic Energy. How?

Question

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?

Geothermal*. Most power plants convert heat into electricity via hot water rotating a fan. The neat thing is it doesn’t matter where the heat comes from, as long as it’s hot enough to spin it.
