Raindrop energy harvesting is a rubbish idea. The raindrops simply don't have a meaningful amount of energy to begin with: https://news.ycombinator.com/item?id=36907674

Yeah, the whole article is a bit fishy:

In addition to generating clean electricity, the new ITO-silver window coating creates a cooling effect by allowing only the visible part of the light spectrum to pass inside. Other parts of the spectrum are reflected outside.

So how would a room actively cool down, when you let only the visible light spectrum inside? Sure it might not get as hot as if you let all light inside, but it will also not get colder.

Honestly, if this was all it did I'd want it. Our house is south facing and the front of the house gets very hot in summer. Windows that effectively limited the amount of heat that could come through would help a lot - even if, as you say, it doesn't actively cool
