Yeah, we can use whatever as long as it holds the energy without loss. A suspended load has zero loss - so does a bunch of water behind a dam.
I don’t see how thermal could do that though.
Another neat tidbit I learned while researching pumped hydro is that hydroelectric dams actually use the remaining inertia of the spinning generators to pump water back up the dams, which is much like the idea of regenerative braking in EVs
Some of them. Others, like the Kidston one use solar.
When I was first learning about this stuff, I (very incorrectly) thought that the purpose of the battery was to generate (rather than store) energy, so I had a hard time wrapping my head around how they could actually work. The idea, however, is that you have your main source of green energy, and when the grid can’t take more energy, you use the excess to pump the water or lift the weight. Then, when the grid needs power you release your weight/water. In this regard, it builds capacity and stability of a green grid.
Thanks; I’m just waking up so it didn’t click
What do you mean it is fast?
I’ve seen this playout too, and it’s tragic.
I forgot about that.

Their algorithm is already abrasive enough. I routinely find myself following people I did not elect to follow. Throw some stupid adds in there, to just make it worse…

How can it be more clear that they actively tries or overturn the election?
The writing is no longer on the wall; it’s a giant, flashing neon sign in your living room.
Seriously
I played a ubi mobile game for 2 years, and then they just flat abandoned it. Stopped support. No new content. Nothing. No warning either
As gamers grow comfortable in that aspect… you don’t lose your progress. If you resume your game at another time, your progress file is still there. That’s not been deleted. You don’t lose what you’ve built in the game or your engagement with the game. So it’s about feeling comfortable with not owning your game.
Yeah, you know I don’t lose my game either saved on my CPU or Xbox with a copy of the game I don’t have to pay for more than once for a predetermined value.
This is pretty cool. Potassium reserves are expected to run out in the next 50 years
This has been a gripe of mine for a looong time and not just in cars. For fuck sake, my fucking oven is touch screen and has wifi. why?
Every time I wipe it off, it thinks I’m touching 37 buttons and it overwelms the CPU, and the system restarts
Never again
This.
I had an iPhone for a decade with my work. Quit both of them and got an android. I’m way happier being able to do things more than one way and to be able to customize everything.
Phones in general suck, but if the shitty, android at least let’s you do what you want.
Powered by Gnoosic.com I use both of these religiously
This is why pumped hydro is a lot better. 250 Mw from Kidston is nothing to sneeze at. Gravity works in mining situations. The one I linked to stores enough to power 1000 homes for a year
