Well if you are going to use the blimp to transport things it would be pretty heavy right?
Wouldn't that require a LOT of hydrogen? Which would require a LOT of energy to compress?
And an enormous hydrogenbaloon isn't too safe around heat? How about using helium?
So you could harvest potential energy from the rain by for example anchoring floating devices on the bottom of water reservoirs used for hydropower?
By first emptying the reservoir (running it through the tunnel to the turbine) and transfort the original PE to electricity, and then anchoring...
I guess I am still unable to get my question across.
Let me put it another way. Floating is a result of differences in density, correct?
So where does the energy that makes for example two liquids of difference density change place come from?
Or another scenario: if you have a floating...
Thanks for answering, but it didn't really answer my question.
You could theoretically (if there was such a thing as "no energy-loss") get the energy you used to pump the water back (using a turbine for example), and the boat would still be hanging in the crane..

Hello!
I have been pondering about potential energy and ship locks.
Big ships tend to have great mass but are also, hopefully, able to float.
So I am wondering if the water in a lock gets compressed by the ship's force of gravity?
If not, you could raise the ship by pumping water into...
