Bimbo is American and feminine, the correct masculine term would be “himbo”
You missed a trick not calling it the leftorium.
What, precisely, do they cover?
neato. Cool project.
So are the vertical cutoffs either side the result of string length, or what’s going on with that?
fucking. why. if new reddit is soooooo fucking good just stick with it.
Neat.
Yeah, I was imagining it would probably work better with water instead. Sand can’t be pumped (or turbined lol), and I noticed those many enormous trucks carting the sand around underground which seems to introduce an enormous efficiency loss to the system. Good to see the fundamental concept works well in practice, thank you.
I wasn’t suggesting that a turbine could be used (directly) for sand, I hope you didn’t get that impression, I was just trying to address that commenter’s point of confusion about generators and turbines.
To your question, a flow is cause by a difference in energy potentials between two connected points in a system; Potential energy causes the gas or liquid to flow through a turbine. The more potential energy, the higher the speed, or pressure (depending). Also, not all turbines drive generators. The output could drive anything where you need rotational input, including a vehicle’s transmission. For a lot of reasons, that isn’t usually done.
If I understand correctly, the idea is to store something heavy up top, send it down below using the weight of the sand to somehow (unspecified?) generate electricity, then send it back up when there is an excess supply of energy generation, leaving it available to use again when energy production is reduced. Battery really describes this system better than generator, because it’s only a hole in which to dump excess energy and then pull it out (which, in a roundabout turn of events, the “hole” in this instance is above ground, and then you “pull it out” of the hole by sending it back down.).
All that said, this seems like a boondoggle. I think there’s a lot in this press release that is unsatisfactory, and I’m extremely skeptical that this makes good sense until I see definitive independent proof otherwise.
The turbine is the part that turns potential energy into rotational energy. The generator turns that rotation into electricity.

I’m missing this from RES. “day x of posting y until-” ZAP
Tildes is not growing, they still just have the one admin for the handful of thousands of posters. I honestly can’t figure out what the strategy is over there, because the stated plan was not being enacted last I checked. Also, the admin is a tightass.
No, there’s definitely some infrequent advertising on lemmy. I block it (and frequently any community that contains it) or I’d point you at two or three examples I’ve seen in my time here.
for that bot-infested shitposting dump?
uh,
