I’ve always wanted to ask someone who knew something about this stuff if this idea is feasible:

Imagine a giant empty bucket held high in the air. As it rains, the bucket fills and using a counter-weight it slowly lowers down to ground level. Now the bucket is covered and the water is slowly drained causing the counter-weight to lower to the ground and the bucket to rise in the air again.

If this were geared properly, could energy be generated in any meaningful amount?
