Darn the person who dropped the box of cards and had to sort them out in the right order. For thar you have a card sorter, later computers sorted the cards first anyway, and depending on your punch card system, you can easily sort them with a knitting needle.
Spinnin reserves is an outdated term, they technically don't exist since decades. A gas turbine is on 50% power in 30 seconds from a cold start and on 100% in less than three minutes, usually around one minute. Pumped storage takes a second or two and can dispatch anything from 1% to 100% imediatly.
Unfortunately, the first time I heared about flash cards I was nearly finished with school. Actually no one ever told me that you can 'prepare' for a test. So I never did that until 13th grade. And later in university ofc. Except for languages I had no problems in school, though.
That is why no one is planning to go for solar only:D Your cloudy weather systems are perfect for wind power:D
Anyway, the core of the discussion was: a pumped storage plant looks completely different than a "huge dam". And they work different. Hence, you can have much smaller pumped storage plants than you think. Hint: the hight difference is the key, not the size of the water surface.
Anyway, as long as renewables do not top base load demand, you have statistically not much energy left to store anyway. Baseload in Germany is roughly 40% of peak...
You need the capacity to provide millions of people will their energy needs for several cloudy days in a row. Switzerland is planning to become that central power storage for Europe.
We are talking about weather or not you need a Hoover Dam like plant design. And we are talking about the question if you need to flood one of an American state. We are talking about the question if the USA is running out of geographical options to build pumped storage. All your ideas about those questions: are wrong.
Your Tesla example makes no sense. Pumped storage is used for "load balancing", not to store huge amounts of energy to charge Teslas, later. You would charge the Teslas directly instead of storing the energy first elsewhere. That is a no brainer.
So thanks for not even trying to follow my argument.
Might I suggest you read the stories rather than just look at the pictures Nope, the point of the stories are precisely the pictures... you seem not to get that. The stories I linked are irrelevant for that. My point is: a typical pumped storage does not look like a Hoover dam. There are plenty of places where you can set up pumped storages. In germany we still have about 30 places free to build storages like I linked.
I only showed you the pictures so you get rid of your impression that a pumped storage is based on a valley that is closed with a hughe hydro dam.
Germany already has enough pumped storages... how you come to the idiotic idea that one of the reservoirs would only charge 5 Teslas is beyond me. You likely mix up power with energy.
Those pumped storages are used for balancing power, not really for "storing surplus energy".
Total storage capacity in Germany: close to 50GWh. (The numbers in the link above are from 2005)
Why you need a "Tesla comparision" is beyond me. If we had electric vehicles in enough abundance, those would be directly used via smart grid technology as "storages". Well, not really storage, they would be charged with surplus renewable power instead of fossile power.
Actually that's *exactly* what it is, No it is not. I suggest to google for some pictures, you will find plenty that don't look like the typical Hoover dam.
Don't know how you come to your numbers, the USA only need to increase pumped storage by a factor of 4 what they already have. That is for all currently thinkable renewable scenarios enough.
And both golf as well as gulf are valid english words:D so no red underlining. Except on this broken windows 10 installation where every word except "so" and "red" is red underlined (why red is not red underlined is beyond me).
Financial vulnerable, yes. Blow up a part of the pipe and the trains stop for weeks. In terms of human life: absolutely not vulnerable, unless you can blow up the pipe when a train passes. Seems exactly the same thing like blowing up a train on a regularly rail to me.
Ever heard about: a) global warming? b) golf stream?
Norway is not as cold as one would imagine. Considering that it is 2000km long from north to south there is a great difference between north and south, too.
Of course it is. Nevertheless a cube with the size length of 1/10th of a meter contains one liter and if you fill that liter with water it has the mass of 1kg. So... what is your point?
Or more simple, a cube with the size length of 1 meter contains 1000 liters, and if we fill that with water we have a metric ton (1000kg). That was simple, wasn't it?
... getting a girlfriend involves first dating women.... No, that is mainly an american thing.
If some romance is in the air, I invite my desired future GF to dinner at my house. Or she invites me to her house. The idea that I have to have half a dozen 'dates' and on top of that 'pay for them' is an american thing.
I thought the whole point of dating is to go out with rather random girls, pay their bills, and have sex with said random girls. But perhaps I understood american culture wrong:D
Weight is not force... read a book about physics;D that is why force is measured in Newton and weight in kg or pounds. Ofc. you can convert one into the other and say: "on this planet, this mass of 1kg is exercising a force of 3000N, and thus weights 300g".

Warrants are issued by a judge!

It is a weird trick, and how "the trick" basically works is right in the summary. Facepalm.

Those are all pumped storage plants without a dam and without flooding hundrets of square miles.

A hydro pumped storage plant is not the same thing as a hydro dam. Facepalm. Hence you have plenty of places where you could build some.

Yes, the unit of force is Newton.
And you insist it is the same as weight (kg, pound etc.) since ... how many posts?
Ever heard about:
a) global warming?
b) golf stream?
Norway is not as cold as one would imagine. Considering that it is 2000km long from north to south there is a great difference between north and south, too.
Hu? Most electricity in Norway comes from Hydro power. ...
And that most Teslas are old in Norway should be no secret
Of course it is. ... what is your point?

As long as the code is already in the App ... there is no problem.
No, that is mainly an american thing.

really likes you and that's how one generally obtains a GF.
And for that you don't need to 'date'.
And you have the right, but unfortunately not the obligation, to not be (or behave like) an idiot.
I thought the whole point of dating is to go out with rather random girls, pay their bills, and have sex with said random girls. But perhaps I understood american culture wrong :D
We just get a girl friend :D ...
I never "dated" a woman in my whole life

If he was addicted he would do it 3 or 4 times _every_ day.
Not 3 times a week for 3 hours.
