the literal rotation of the planet causes them to precess, losing like 5% an hour. when you install them you have an angle setting to minimize depending on latitude but they're still only good for short term stuff or load leveling, they have amazing energy storage density so they're still used in DCs that are space restrictive

flywheels do have some potential (:haw:) but the problem is that to store any appreciable energy they need to be spinning really fast and the materials dont hold together. this is why the F1 kers flywheels are carbon fiber and poo poo, the thing's on the verge of centrifugally transforming into a metallic mist when its fully spun up

Bearings are a bitch too but we're getting past that with magnetic and foil bearings (again, neither of which work[well] at low speed)

we have flywheels as part of our DRUPS at the DC its pretty cool that you can pull more than a megawatt of power out of a 5 ton bit of concrete spinning in helium. there is another flywheel to start the generator with a giant clutch.

theres just not enough sites to make this feasible for storage at any reasonable capacity. like, not enough by a couple orders of magnitude.

theres an interesting solution where you dig a big, deep hole, put a giant rock plug in it and pump water underneath and use the potential energy from that but i dont know how proven it is.

i think someone did the math and weirdly enough giant loving lead acid batteries were still the #1 bet for massive load balancing batteries.

I had a similar idea involving catapults and very large dense rocks at one point.

Shaggar posted:

No poo poo. "Our weights are denser than water therefore better" completely ignores the fact that hydroelectric doesn't require a mechanic to monitor and maintain every hundred cubic feet of inert water individually. Also, I can't imagine that the numerous engines and electrified tracks required to match the energy potential of the "gigawatt dam" claimed in the video would cost less than the dam either initially or over time.

edit - another thing: I thought local power storage and local power generation via battery packs and solar panels (or whatever) was considered beneficial, particularly to consumers who might like to have power during a rolling blackout. What's the rationale for shifting power storage to the side of a big mountain in Nevada? How does that alleviate grid overloads?

energy storage is extremely my poo poo, but it's really hard to find any references that are not just news about energy storage companies that failed 5 years ago.

one energy storage solution that my friend told me about, that kind of blew my mind, was that some cold storage facilities simply crank up the cold by a couple of degrees during the day when they have free solar energy and then let the facilities warm back up in the night before starting to use grid power

molten salt is great. i particularly like the environmental/danger profile - if your salt battery breaks open you're dealing with the menace of...a basement full of warm salt sludge, as opposed to a lithium fire or a disintegrated flywheel or lead-acid spraying over everything. mining and deploying salt batteries is a lot easier on the environment than lithium too

still has engineering challenges. metal parts + hot salt sludge = corrosion hoo boy, and non metal parts have trouble with the heat

long term maintenance is an absolutely pain in the rear end with pump storage and you need good topology for it. once cracks start forming in it, every gallon you lose cuts in to your efficiency and its difficult to find and repair them while in operation. they have scuba teams doing constant inspections on facilities and is dangerous work, because you can just get sucked in and killed at a leak. placement is much easier if you just need a grade and likely won't see the same rate of diminishing efficiency through the lifecycle, not to mention servicing costs will likely be lower. probably worth some trade off in efficiency due to increased friction

well if the markets crash theres technically a potential that credit markets dry up again, and with it VC money as the former billionaires (now lowly millionaires) flee to cash which would mean that the crazy funding rounds are over which would potentially kill the companies that rely on VC money to continue operating, so all of them.

a lot of people are thinking that what we'll really need to do is to start making a bunch of energy intensive factories that manufacture fuel from various things (eg you can make jet fuel from a bunch of water and carbon dioxide if you have a whole bunch of electricity and some catalysts). this will work to use up all the massive spikes in production we're likely to get during the days from mass solar installations, and can somewhat help with fueling things that batteries still don't really work for.
