Someone is finally starting to do something with an idea I thought of a while back. House sized electrical storage using used EV/Hybrid batteries.
We'll have to see how much used EV batteries run for and if they are even purchasable. And how difficult it'll be to build a controlling system to power the house overnight/during blackouts. Solar panels, at least here in Colorado, aren't allowed to power your house while it's attached to the grid if the grid is down. This is blatantly stupid and their excuse for it when questioned is also transparently bullshit. Gotta find some way to use the power I generate only here in my house.
