Batteries. Like I said
The environmental impact of batteries is much worse than what carbon dioxide can cause, not to mention degrading and disposing of them once they finally fail.
There was a system I saw somewhere that uses an electric motor to lift a heavy weight to store energy, then allows the weight to descend during hours of demand. I thought it was a brilliant option that is far more Eco-friendly. Sure, you can’t do that with a phone or a car… but a series of cement slabs hoisted during the day by solar power and allowed to descend while spinning a turbine? Yeah, I can see a benefit in that.
or, batteries in the concrete slabs hoisted during the day by solar power and allowed to descend while spinning a turbine, creating power and allowing the batteries to trickle charge 24/7.
I think there must be a little energy lost in heat due to the mechanics but otherwise it sounds pretty good if it’s well set up. Be good to have a link!
That is a mechanical battery - something that’s existed in history for thousands of years and yeah it sounds like something we should account for
Yup, that’s the point. The use of counter weights can be used to re-hoist the blocks.
Yes, I also agree
Glad we’re all on the same page. Who’s going to tell apple?
Not energy storage, but:
So cool - you could dig a pit in the garden for those, I imagine
Or even attach it to the back of your car! I’m such a genius
Mobile phones… wrist watches… man, this is perfect
