Gravity-based energy storage tower developer notches a customer order 7

Interesting that their claim of 10MW is equal to the most powerful mine lift.

https://new.abb.com/mining/undergro...stems/deep-mining-most-productive-sustainable

That's 60T at 20m/s assuming a vertical lift.

So I guess their rate is doable. What I find problematic is their MWh claim. To raise 60T 3000m requires 0.5MWh of energy. That means their weight will have to be 48x the maximum mining load of the most powerful mining lift in the world.

No sweat; they only need a single 27-km shaft to store 4 MWH for their pilot demonstration in Yorkshire or, about 30 1-km shafts, I suppose

OMG ....There you guys go again !!! ....

Being all "sciencey", using common sense and pointing out those damn "laws of physics" !!!!

If you guys only had "MBA vision" .... we could make this gravity "whatchamacallit" thing happen !!!!

Why don't you Damn Engineers fall in line, take responsibility for the project goals and make this all happen !!!

What the hell is wrong with you ???

Now repeat after me .... the sacred MBA Credo:

WE CAN DO ANYTHING, WITH ANY PEOPLE, IN ANY AMOUNT OF TIME ...

WE CAN DO ANYTHING, WITH ANY PEOPLE, IN ANY AMOUNT OF TIME ...

WE CAN DO ANYTHING, WITH ANY PEOPLE, IN ANY AMOUNT OF TIME ...

Any more comments, gentlemen ?

We think the Vault is a ridiculous proposition, unworthy of a high school science fair, let alone the $1.6 billion valuation by which NRGV came to market

LOL

The problem with sloppy work is that the supply FAR EXCEEDS the demand

We've got another loser:

We asked Geason how much energy the device generated during the trial. "It's critical to note that the demonstration on King Island wasn't aimed at generating a large amount of electricity,"

Hey, at least they acknowledge AGW and are trying to do something with it.
