Wind turbines used to absorb a power surplus?

Any real ones? What the tractive power of a Mancoon?

I feel tractive should be a word, and my newsreader accepted it, but I've never heard it used.

Yes.

Wrong with work and skills stereotypes.

Sure, but there are FAR more women that can't even do something as basic as change a flat tire on a car.

A female mate of mine believes she is very capable just because she can drill a whole in the back of a media cabinet to put the cables thru.

Yes.

Not convinced about that with doctors and specialists.

In the end that isn't really an issue. The issue is how many units of energy it takes to make a system that will deliver you one unit of electricity back, reliably, over its lifetime.

It it's more than one, it isn't sustainable. It its more than 0.1, it likely isn't really sustainable either, as it doesn't leave much energy left to do anything but plant windmills and solar panels.

With power steering, and brakes there is no earthly reason why a woman F1 champion should not exist. Pat Moss and Michelle Mouton did it in rallying, which has lots of corners.

A one tonne block has a weight of 9800 Newtons, so lifting it through one metre takes 9800 Joules, which is 0.0027 kWh.

And that's a problem, if you want to use lifting mass to store energy, because you need to lift a lot of mass through some reasonable distance to store a worthwhile amount.

For example lifting a thousand tons through 100 metres, stores less than 300 kWh.

One thousand tonnes is already multiples of the mass that a typical wind turbine tower is designed to support. It's just not practical

Finally, someone who Can Do Sums, instead of hand wavey 'why cant we just?'

Because it's impractical to run multiple distribution pipes and wires in a city.

A local utility can seek competitive sources of gas and electricity if large-scale transmission permits.

Some things here are excellent.

You'll never be popular here doing that "mathematics" stuff.

Not with John Larkin. He wants admiration, not illumination, and thinks that everybody else who posts here shares his insatiable narcissism.

It isnt done with multiple distribution pipes and wires.

One operation does the pipes and wires and competing retailers sell you the electricity over those,

She's not into being popular. She makes a complete pest of herself claiming that the local authoritys are doing what the legislation does not allow them to do and ALWAYS gets them telling her to go and f*ck herself using appropriate bureaucratic language.

She is also a stupid nudist.

Desiré Wilson did score a win at Brands Hatch without power steering but was more successful in other types of motor sport.

I've only seen one F1 race and that was at Watkins Glen in the mid-60s. It wasn't very exciting for someone who grew up with 1/4 mile dirt tracks. The SCCA races at Limerock were much more interesting.

Is there any group where you are not the #1 troll?

What about saltwater batteries to store excess power? 4 times the capacity of Lithium, and cheaper:

That's not the complete story; customers withdrew megamillions in a short time, in a run on the bank. Arguably, a bigger bank, or one with less volatile clients, would have survived.

The looser regulations made the clients nervous, it appears.

Other things being equal, if the torque goes up, so does the power output.

If you want to increase the torque to limit rotor speed, but at the same time there's problem with wind power overproduction, then you're caught between a rock and a hard place.

Well that's unreliables for you.

Half the time they ain't producing worth a damn, and all your expensive infrastructure is sitting there idle, and the rest of the time they are producing so much the infrastructure cant handle the peak flows, so you pay them to shut them down

You don't have to run multiple cabling systems.

The UK did it by splitting the distribution network off from generating completely. They effectively rent usage of the national distribution grid network proportionate to how much power they put into it.

The producers of electricity then have to compete to supply their electricity to the National Grid. UK system is deeply flawed because the price they get paid is linked to the cost of gas turbine generation (and not a cost to produce plus some margin).

This has produced some enormous windfall profits for real energy generation companies and conversely large scale bankruptcies of deregulated energy box shifters who had no clue what they were doing. Basically they were destroyed by fixed price retail sale contracts and wholesale gas prices more than doubling in a very short period of time.

Certainly you would never do it the way the UK does unless you were out of your mind.

Who wants to buy their electricity from a company named "Octopus" (genuine name - I'm not making it up). "Bulb" went pop!

A full list of all the deregulated and clueless suppliers that have gone bust in the UK up to Feb 2022 is here - massive increase in the daily standing charge to pay for bailing them out.
