One motor can lift a very large number of heavy blocks, and the mass of the blocks does not need to be sent from earth.
- nanomonkey 5y agoSadly the moon's gravity is 1/6th of the earth's, so each block would have to be six times the mass, or you would have to lift it six times as high to store the same amount of energy.
