Elon, You're Digging the Wrong Direction!! Geo-Heat/Energy

[Evbwcaer]

Yesterday I came across this story:

What's Inside the Deepest Hole in the World?

about the deepest drilled hole in the world, about 7.5 miles deep in Russia. At the bottom of this hole you will find 350f temps, 350f/177c! A hole in Germany saw about 600f/315c. The Russian bore was a huge and expensive undertaking, but is deeper than would potentially be needed, depending on the desired temperature and local geology.

One of the best renewable sources of energy has got to be, "liquid hot magma".

If holes like this could be drilled economically, you would have a massive source of steam for heat and electricity. Imagine a green house built on marginal land that uses water, heat, and electricity from the hole. It seems like an overlooked resource
that would be very reliable, rich, and durable. The consistency would act as a battery. Maybe there is even dissolved lithium in the water!

Actually you only need to go 5-100 feet down to simply save energy as opposed to generating energy...

Dandelion Air - Dandelion Energy offers Affordable Geothermal Installation Services

Interestingly most of this Google/Alphabet X spinoff IP is around drilling, not heat transfer.

Unless it's a geologically active location like Iceland or Hawaii it's not cost effective.

Also... sadly... generally not cost effective. Air Source reduces energy use by ~70% at 1/3rd the cost. Investing in Air Source + PV is generally more cost-effective than geothermal.
