Back when this idea was first floated for investors several real and notable physicists and scientists pointed out how inefficient and just stupid this is.

Just ask an engineer.

This has been completely debunked. If you want to do storage like this, do a hydro electric dam set up. This ends up costing 100 times as much as a hydroelectric dam wood.

How is this nonsense still going on.

So how does it work?

Wouldn't a giant water tower be more efficient to store energy with fewer moving parts compared to all the cranes?

@TheBooban 2 ай бұрын

Yeah, but still, the water at the bottom, just like these bottom block, has no more energy left, no pressure. So not an efficient idea. Can move it up a mountain, but Mother Nature moves it best and then we dam it.

@@TheBoobanThere's no need to store water at the bottom. Every suburban reservoir has a pressure tower with the stem having relatively thin pipes and a large bulb at the top where most of the water is stored.

@@mikejosef2470 Sure, but different purpose, acceptable for pressure, not energy storage. You can't store the necessary water on tiny little stems to store. You need a dam to store water at scale, which is why this guy used blocks, but also a bad idea. This idea only works if you already have a dried out dam nearby :D

@@TheBooban I agree that the small scale isn't worth it, but I was just pointing out that your specific objection need not apply. Pumped hydro is a far better way of using gravity to store excess energy from renewables (other than hydro itself) and in many cases simply maximises the energy storage of existing systems that for whatever reason are not already full. That said, an enormous tank and/or artificial lake hollowed out from the top of a large natural hill with a similar storage at the bottom might be a decent small scale energy storage for a small (country town?) scale solar energy plant.

this has been debunked as stupid so many times, many years ago. just stupid

The interviewer is correct... it is complex, and needlessly so. It is unusable when it is windy, and even under the best conditions, it requires placing huge blocks with literally millimetre precision, while they are hanging from 70m cables. The cranes have hundreds of moving parts, and have to be both efficient lifters (electric motors) and generators. And a collapse, which could easily result from slight misplacement a few times, or from the use of substandard materials fracturing, results in the complete destruction of the entire facility and an enormous mess to clean up. There are stupid ideas, scams... and then there's this.

Um, why not just use water? Pump it in during energy surplus, drain it out during deficit. You can probably use the same turbine for both, just "reverse the polarity" this block solution sounds like a recent college grad idea.....

Why would this poser have Bloomberg running in the background lol. Why would any CEO be so focused on the stock price... Just look at what was going on at Boeing.

They covered Theranos and even had sit down interviews with Holmes. In the world of "financial news" every scam is a legitimate business until they are convicted.
