These guys used to be all about underwater CAES using energy bags, but it looks like they pivoted to some sort underground cavern with water CAES.

Mail Rail
They're resurrecting the London mail tube trains as a tourist attraction for the postal museum, but they won't be using all of the old track (0.6 out of 23 miles).

Apparently a "dry" fracking technique using no water, just gelled propane (WTF?!?). Interesting methodology...

Gravity Power Grid-Scale Electricity Storage System
Basically uses a closed loop of a large and small bore vertical silos linked together, with a huge weighted piston in the large bore, and reversible turbines at the surface level to complete the loop. Sane if the drilling of the large bore doesn't cost a fortune. Prefer to do it in a seismically inactive area unless you can figure out how to keep the bore from collapsing in an earthquake. Since it's closed loop, head pressure is not the defining characteristic, rather the bore depth determines the drop time like a gravity clock. The trick is the raw bore depth head pressure isn't the driving force, rather the weight block's applied pressure. There is the potential to even do this offshore using floating pipes anchored to the bottom.

MOUNT10 · Guarenteed Backup · Swiss Made
Yet another underground nuclear bunker datacenter (?YAUNBD?) that likes to claim it's the swiss fort knox, and offers an online data backup service. Apparently also holds a physical time capsule of digital data formats for archival retrieval/conversion purposes.
