gravity battery idea

[trevorjohnson83]

if you stored a water in a 20 foot cube at the bottom of a 100 foot well so its 120 feet deep total, how much power could you store this way?

Final Answer:​

You could store approximately 22.6 kilowatt-hours of gravitational potential energy by placing a 20-foot cube of water 120 feet deep in a well.


Let me know if you'd like the estimate adjusted for efficiency (pumping/generation losses).

Aren't you going in the wrong direction? The idea of a water battery tends to involve pumping it up the hill, not into the ground.

This is already being done.

In Chattanooga TN some of the alternators at the generating nuke plant are so large they cannot ever stop or they will destroy the bearings they ride on.
So the plant always produces excess power during off peak times.
They utilize this electricity about 60 miles away to pump water out of Nickajack lake to the reservoir built on top of Raccoon Mountain.
Then during the peak times they let the water back down the mountain and create more power from it.

Seems to me that if a few good minds put themselves together they could figure out how to store lightning in underground batteries for later use.

Ummmm
Electricity is power....meaning it is movement of electrons to normalize an imbalance. Static electricity can be artificially generated BUT it has no amperage. It has voltage but not many amps. (Voltage causes the sparking and arcing) You can do this with a rod of rubber and wool.

Now the actual arcing is what has the potential for usage as it generates light and heat....but the amps? Not really. Because of the high voltage it generates intense heat that burns all known metals.

It's more destructive than constructive.

Power lines attract lightning. (Most negative to positive) transmission power lines are protected by grounding lines placed on top. (Distribution lines have the grounding on the bottom)
