See-Through Windows Make Clean Electricity From Raindrops

  As opposed to opaque windows?

    Transparent vs translucent.

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

    Yeah but a journalism student just learned the phrase “triple threat” and wanted to shoehorn it into an article

    I’m sure his mum pinned it on the fridge

    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.

      They subscribe to the theory that less forward acceleration is the same thing as slowing down.

      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

    I mean, not in the sense that they’re trying to do it, but that’s ultimately what drives hydroelectric dams.

      Sure, but those are completely different approaches. Dams have the advantage that they have a much larger capture area for water and that they can accelerate the water beyond the 10 m/s terminal velocity of raindrops.

  I cleaned my windows yesterday. Now I can finally see the outside through them.

    They actually got better? Nice work

  Someone should explain why this is ludicrous.

  • metallic_substance@lemmy.world ⁨2⁩ ⁨months⁩ ago

    I have the same thought. Predicably, someone did ☝️

      Yes thanks, … in fact, linked from @stuner above, is the explanation detailed simply, rapidly and from proven science why this source of energy is negligible and nearly never working.
