The problems are that rock isn't a good conductor of heat, so once you've cooled a bit down, you have to wait for it to warm up. Warming only happens very slowly at the rate of < 50mW / m² which limits the amount of power you can get out.

- cameldrv 11mo agoCouldn't you frac the rock like they do with oil and gas drilling or have a branching borehole?
- kragen 11mo agoYes, that's what this article is about.
