Mildly Interesting

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

Yeah, the thing is the "unpowered" part. Look how much energy an AC chugs to achieve that cooling. This tower uses wind power to do it's thing.

The AC is also small compared to a literal building with a sewer underneath and doesn't require a windy day. Trade offs

well technically it is powered, just directly by wind and water kinetic energy, probably(?) much more efficiently than if it had been converted to electricity first

Do we know it's more efficient? Has anyone done the math?

AC really doesn't consume that much if designed and sized properly. It's nothing like the energy consumption of standard heating. The problem is all these people going out and buying the cheapest floor unit or undersized window unit they can find, then the wheezing thing just sits there chugging 100% of the time because it can't keep up with their space. That's super wasteful.
