www.naturalawakenings.com/2020/05/29/309102/generating-electricity-from-rain “A surprisingly high voltage can be generated from raindrops using a field-effect, transistor-style structure, reports a new study from the City University of Hong Kong in the journal Nature. A single drop can muster 140 volts, enough to briefly light up 100 small LED bulbs. The new design couples an aluminum electrode with an indium-tin oxide electrode layered with polytetrafluoroethylene (PTFE), a material with a quasi-permanent electric charge. When a raindrop hits the PTFE/tin surface, it bridges the two electrodes and creates a closed-loop circuit that helps fully release any stored charges. The technology could handle sustained rainfall, as well. If there are continuous drops, the charge accumulates and eventually hits a saturation point. Building rooftops could supplement some of the electricity used inside, and electric boats could extend their range.” My notes: Interesting!

I think it would be a pretty cool way to generate electricity for our homes. It is my ultimate goal in life to be completely 'off the grid'.
Maybe one day!

Lee, That's a good goal! It's one of ours too. Healthier all around.

If it really worked well, couldn't you use a water pump to spray the water onto it to make the electricity. It would create the electricity to run the water pump, and even more to be stored and used for other things. Not sure how it actually works, but that would be interesting. It would be like a self sustaining cycle.
