It’s a nice idea but impractical. Energy = mass x gravity x height

Say 10 tonnes of water pumped into a massive 20m high tower… E =10000x9.8x20 Joules. ≈ 2 mega joules.

Theres 3600 joules to a watt hour so divide that and you get:

≈ 550 watt hours (0.55kWh) of storage (assuming perfect efficiency of the turbines). About the same a half a dozen big cordless tool battery packs.

Thank you for actually answering OPs original question and the follow up.

No. I see where they’re coming from. You’re not embracing the spirit of The Fucking Corolla.

You think you’re replacing just a radio but who knows what kind of imbalance you’ll introduce.

It’s a Corolla, without Bluetooth. That’s the rules. Dont fuck with it.

I’ll take, “things that never happened” for $1000 thanks Alex Ken.

Edit: account with no history. Sitcom scandal. “AITH?”… But, if you WANT to believe, that’s fine…

It’s nothing if it doesn’t have a yellow and black sign of a road worker scratching his butt.

I think for those classic clicky dumb thermostats they should be called thermochaser.

You dial up a temp and that’s pretty much the least likely temp that you’re setting, the f****** think will overshoot panic, u-turn dive back past the set-point hit the breaks u-turn again apply full throttle.

Or perhaps a thermotease. For when you do that fine adjustment to try and make it just barely click then 10 seconds later it’s too hot or cold… so you give it anither tiny tweak thinking you gotta be close but no, it’s miles away from clicking - burning away, quietly mocking you.
