    Kind of an unconventional battery, but I’ve heard of solar and wind being used to pump water uphill into reservoirs and then released through a hydro plant when the sun/wind aren’t shining/blowing. I’d be curious to know the amount of production lost from storing it this way.

      I heard the loss comes from evaporation. Another cool idea I heard was using a mining cart. So its not practical but I think the idea is cook because I’m pretty science illiterate but it got me thinking about what a battery actually is. So you drag a mine cart up a hill with energy produced using renewable energy and then let it go down the hill and collect the stored energy with its motion. Technically there isn’t anything like evaporation so you could store the mine cart up the hill with no energy loss.

        Interesting. Didn’t consider the evaporation. I imagine friction could effect the minecarts, but no idea to what degree. Some loss is gonna happen so matter what. If I’m understanding correctly, even nuclear, built away from population centers, will lose some power due to transmission distances.
