You will need a lot of really deep holes to make significant power in most places. Of course you can get to the mantle from anywhere on earth. That doesn’t make it practical.
Each hole needs to be only dug once and then generates heat for easily a billion of years.
Don’t be a pedantic shit.
How uplifting of a statement you made there. I guess I hit a nerve there.
Works when you have a lake on a mountain and a lake below the mountain. 90 percent of places? No such luck.
“The lake on the mountain is built upon a flat surface, requiring a dam around the entire perimeter.”
Building a roughly circular dam sounds not so hard.
Literally just in a mountain or deep underground. It’s been figured out
Funny how nobody does this then. The concerns by scientists about potentially contaminating ground water is just fearmongering then…
