We already have gravity storage with reservoirs and hydroelectricity.

Thundf00t did a great breakdown on why Energy Vault is a load of bullshit: www.youtube.com/watch?v=NIhCuzxNvv0

I wonder who is getting kickbacks.

Trust Forbes to follow biggest hype of the month. They also have sense for choosing financial criminals for their 30 under 30

Hey, if China wants to hand out money to scammers, theyre free to do it. I should go offer them this bridge I have for sale…

Here’s a hint china: lifting 1kg for 100m, without any friction either way, stores 1 kilojoule of energy. That’s about 0.25 Wh.

So, if you have a 100m tall tower, with a 50kg weight, and no friction, you store about enough power to charge my cellphone.

This is a “solution” looking for a problem

Adam something does a good job of explaining the issues with this design

It got me at first. Because “the concept itself sounds reasonable”, I needed an explanation of the flaws. Thanks for the short, informative video!

thallamabond ,

Glad you liked it, he has a number of other videos that are also pretty informative. I especially like his infrastructure stuff though.

Energy vault is a scam, it’s stupid on so many levels that it’s painful. Yet yerer we are, again millions wasted, like Hyperloop

this is a stupid device, fortunately it can be improved in a rather straightforward way m.youtube.com/watch?v=iGGOjD_OtAM

Interesting idea in its simplicity. If they can get large returns of energy close to batteries that would be worthwhile especially if using only local easy to obtain materials. What a cool system

this is one of the dumber VC baits i’ve seen since cryptobros gone quiet. pumped storage hydropower is superior in every way

naturalgasbad OP ,

Helps because it’s basically entirely a construction effort. If there’s anything China has a lot of, it’s construction capacity.

PrinceWith999Enemies ,

That’s a good point. China has construction capacity like no place else on earth.

I also wonder if the technology involved would make this more deployable in the global south due to fewer infrastructure dependencies.

Haagel ,

The claim to get 80% energy return when the “battery” is discharged.

@dumples@kbin.social avatar

I saw that. Hopefully that is a true energy return and not some marketing 80%. Cool if true
