I feel like I'm missing somthing obvious here.
If I have a load of charge and I give it a pathway to ground*, is there some unforseen consequence?
*like lightening clouds or, umm, earth spikes.
As I say, I'm pretty damn sure that is how off grid systems deal with over generation, but, again, your query makes me feel like I'm missing somthing obvious.
yep
you need this lot

Voltage doesn't kill, current does. Just can make it more likely to.If it's above 50V it has the potential to kill someone
Slightly OT, is that the place with the strange speed limit signs on the entrance road, something like 19MPH?
Anyone they wantAh, but which imaginary friend do you address?
I think that’s Broughton shopping park, very close by. That’s definitely got a 19 mph limit painted on road as you drive in.Slightly OT, is that the place with the strange speed limit signs on the entrance road, something like 19MPH?
See 65mph in Cornwall.On about weird speed limits, I asked recently regarding one. Something like 9¾, it is. Apparently, people pay more attention to unusual numbers, hence are more likely to adhere to them.

40mA is generally accepted as the current that will kill a human but the human body, across the heart. But you need a fair bit of voltage to achieve that, if you're fat then even more. If you stand on one leg with an insulated boot and hold a live wire with one hand you are extremely unlikely to do any damage. How do you think people are able to work on live 400kV lines to do maintenance?

Variation on that theme already in use in a Swiss mine. The dumper drives up empty, gets filled and coasts downhill recharging it's batteries. Generates more energy than it uses.There was a trail of vehicles at one time using flywheels to absorb power on downhill stretches and give some back when going up hills, allowed for a smaller engine in passenger vehicles (bus coach etc.), took a variator style gearbox to work reasonable I believe.
You need massive flywheels to be of any practical use to store this kind of energy. I remember some calcs we did for a medical device that needed lots of energy quickly. Using lead was going to be a 4t flywheel... And that was for something that could be run off a 13A plug...With the increase in wind and solar are there any underground flywheels in use to store and even out the supply, or take access when there is any? I am sure I saw something about it being trialled in some country.

I guess it did not go much further forward?
