It sounds like quite an engineering challenge and a lot of ground to excavate to store a significant amount of water.
Geothermic energy and CO2 storage sound a lot more useful if you’re going to dig that much
- chongli 4y agoI think the idea was to avoid excavating all the ground in the middle. You just cut around the circumference of the piston and along the bottom. The thing I never could understand was how they’d seal the walls of the cylinder against the bore so that water doesn’t fill that space and gush right out the top!
