This is a very cool concept. I could see this "miniaturized" for the home.

How Much Energy Can You Store in a Stack of Cement Blocks? | WIRED

'How much energy can you store in a stack of cement blocks?'

'There are really two physics parts to this concrete battery: gravitational potential energy and electric motors. ', "But that gives 2 million joules of stored energy with just 50 cement drums (assuming energy transfers are 100 percent efficient—which they aren't).", "Or maybe you could use solar power during the day to store energy in the battery to be used at night—you know, when the sun doesn't shine."

'OK. You lift some mass and you can store energy. '
