Reason To Investigate Things We Take For Granted – How Can Water Drops Be Used In Inventions?

I think the earth system is adapted to water drops. Like the rain. Since my guess is that everything is adapted to life.

So there should exist possibilities that have not been explored before regarding water drops.

I wonder if there is such a thing as a simulated rain cooling device. Where you pump up water and let it drop down again. Perhaps all in pipes but still dropping. Like the water in a well is ?cold. Could we cool something with this method?

Philosophically there is such a possibility other than a fountain. We just need to figure out how drops can be used in modern inventions.
