During the heat waves this summer, here in lovely #Cascadia I have been making great use of #EvaporativeCooling
Works quite well here, as we have dry, hot summers, and reasonably abundant water sources.
Got a used commercially manufactured one plugged into the grid for power...
You have to make sure to exhaust the humidified air, but it uses a tiny amount of power (80-120W) for how much cooling it can provide!
