True. I think the higher up your container is the more energy you can store with the same amount of water. of course it takes more energy the higher you need to pump the water. If there is some sort of hill or cliff you have access to then you could use that for elevation.
That'd be a sweet setup! I wonder how much energy a large cistern could supply. You could effectively get a small amount of energy from rain water.
