The statistic you’re looking for is energy density. It’s usually expressed as Watthour per kilo(Wh/kg). Li-ion batteries are somewhere around 300Wh/kg, or about 1 megajoule though less if you’re making it into a building.
Lifting a big weight provides you with Mass x 9.81 x Height amount of joules. So lifting 1 kg for 100m gives you 1x10x100~ 1 kilojoule.
So, to charge my 300kg, 32.000 Wh Nissan leaf battery (130Wh/kg, what you get when you actually build batteries in the real world), you would need to lift a mass of 115tons to 100 meters. So to charge a single car, at 100% efficiency, you need to lift 72 entire cars. Just so I can drive to work and back. And real-world efficiency is far below 100%, just think of the friction.
I think you’ve spotted the reason why we don’t actually build gravity batteries. Imagine lifting 115 tons to 100m, that requires a massive crane, itself weighting nearly half that. That’s why all gravity storage in existence basically consists of pumping water uphill, onto pre-existing mountains and lakes that nobody had to fabricate out of concrete and steel.
Nobody should be taking Uri Geller seriously, so that’s good.
The “Randi is a pedo” is from a very obviously take smear campaign that is about as real as any of the fraudsters randi debunked.
As for mediation, a massive number of the claims about it ARE fake. Randi has some very clear YouTube videos about his opinion on meditation.
It really sounds like you have a personal grudge against the guy. So now I’m wondering which of your beloved ideas he debunked, or if you simply didn’t spend the 40 minutes requires to research these claims.
Btw, please don’t use Anti-Asian phrases created by a literal Pedophile in your debunks (Woo Woo)
Wut? I’m pretty sure this has been a derogatory term for pseudoscience since at least the early 90s. I dunno what you think the origins of the word are, but the only relation to Asian people or culture I can find are in the form of it being used to mock charlatans peddling vaguely Asian-sounding spiritual beliefs.
That seems great for the “we go from fancy campground to fancy campground and stay for half a week” crowd, but most camper van owners are not in that group, right?
Also, negative enforcement is not very effective with cats. Punishment just equals “don’t do it when the human is around”, unless you specifically keep watch from outside the room or something. I’m not saying it doesn’t work, but be prepared to spend months on this.
None of this is practical. You can’t build a tower like this for any real storage, it’s just not efficient. The only effective method is running a train up a mountain, or pumping water uphill. If you have to actually build a mountain a first, it’s not going to work.
