Can gravity batteries solve our energy storage problems?

  > 0.33kW of instantaneous power, enough to briefly sustain around 750 homes Is this the correct unit? That can barely support my fridge. Megawatt would perhaps suffice, but only for homes that really use little energy. Not PC and TV time I guess. Average consumption is perhaps in that ballpark. Still, such a system probably need less maintenance than pumps. Some suggested to pump water into a mountain and slowly elevate it to decrease the area and volume of water needed. But again it would seriously depend on the pumps. And capping a mountain is probably not too easy either.
