So here’s the idea, we dig two super deep holes and connect them underground. The holes would be deep enough that the ground would be very hot maybe ~10 miles down or so. Then from one hole we pump water down it, warm it up, and then steam will come up the other side. That steam spins a generator and generates power. Then you cool the steam in a cooling tower and pump it back down and repeat the process.
We could use this process to renew all old coal plants. As opposed to burning coal, we could re-use the turbines and cooling towers that already exists in old coal plants. This would give old coal plants a new life, and could in theory get the world off coal.
What am I missing here? Does anyone have experience doing something similar? Do you think in 2022 we have the technology to dig a hole that deep?
Here’s a diagram I made of how the process could look: https://imgur.com/a/NTQPh15
