I guess twenty years old counts as "new". At least twice before, in the Philippines and in France, test plants using this fracking tech have been shut down due to causing minor earthquakes. I don't think minor earthquakes were a good reason to shut them down, but then, I grew up in California.

A whole region in NL (Groningen) would beg to differ ... 😉

Repetitive minor quakes caused a lot of damage ...

Yeah, "small" quakes are a very big deal in areas where the construction isn't designed to handle them.

In Northern Canada, a test community has been heated for decades from an insulated pit of water, sand and salt heated all summer from rooftop solar water heaters. It reached 100% solar heating.

This project convinced me no one wants real solutions. The project was dismantled and replaced with gas furnaces.
