Aren’t there a whole bunch of interesting battery designs that can be worked into the land if you design the house to use it?
Like… (1) design the house to have solar, (2) solar power puts tension on giant underground springs, (3) slowly unwind springs for the power.
Or, lift a weight through some kind of gravity generator. Power generates at night when the weight falls back down.
I don’t know… I’m just assuming there’s got to be pretty neat designs when you figure that you’ve got a giant plot of land and only need enough power for a home on top of it. Do we really need to rely on giant chemical battery manufacturers?
Undecided Matt Ferrell did this with his new home minus the springs, he uses his underground for geothermal. I'm basically doing a retrofit. Solar panels on roof and in my yard if I need them to meet demand. Sodium batteries if I can get a good deal, else I'll find a wrecked EV on the cheap and get the batteries.
I hope you aren't putting wrecked EV batteries anywhere there may be flammable anything, such as near your house, your neighbor's house, a forest...
