Rain has has a lot of energy in it, from whitch we can harvest energy.
Let the rain flow, down the hill sides, down to a river. Block the river so you get a higher level of the water. Let the water flow down pipes with a heavy force. Lead the water into propellers and you have rotational movements. Align this with generators and you can get a lot of ener ...[text shortened]... called hydrodynamic powerplants? Oh, I had no idea... I thought I came up with this invention...

Then it will not work. You can't get much energy out of raindrops.
We are not talking about E=mc2 here, are we?
