asteroza + silo   13

This one is a straight up winched weight in a shaft, rather than vertical bore hydraulic piston

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.

Slashdot Comments | Job Ad Hints At Microsoft Move To ARM Servers
If this is a real Microsoft anecdote, it makes you wonder why Microsoft didn't partner with a PDA maker and one of the big storage companies like EMC to make a robotically managed ARM blade server silo/rack? Real blade servers now are approaching the sizes of LTO tapes. It then becomes a question of how much local SSD storage you want in the ARM blade, versus accessing a SAN over the blade backplane?

Well, that, or do a drawer setup of 3U or 4U drawers containing many vertically mounted blade servers, like a Sun Thumper storage server.
