The hillside projects would mimic the UK’s traditional hydropower plants by using surplus electricity to pump water uphill, and later releasing the water back down the hill through turbines to generate electricity when needed.
But the “high-intensity” hydro projects use a mineral-rich fluid, which has more than two and a half times the density of water, to create the same amount of electricity from slopes which are less than half as high.
The company behind the plans, RheEnergise, said the project would pump the dense fluid up a hill with a height of 200 metres, at times of low electricity demand. It would be held in an underground storage tank larger than an Olympic-size swimming pool.
This high density fluid, there’s no formula for it revealed. But OK, so, something that’s 2.5 times the density, that should indeed mean you need a smaller drop to generate the same power, right?
Move 250 lbs through 100 yards, same as 100 lbs through 250 yards – right?
I’d probably start muttering to myself that density and – well what? viscosity? – are closely related and we might not expect a thicker liquid to turn a turbine in quite the same way. But, umm, the initial insight is valid or not? That initial insight by these developers that is?
That they’re flogging their stock online through their website is a different matter……
