I wonder how practical it would be to sink 30 foot deep concrete tube shelters with a ladder and a lid. They could serve as emergency daytime shelters and someone could climb out at night to search for a location with working power or cooler weather.
- rtkwe 5y agoThere'll be issues keeping that cool and the air fresh putting enough people into them. Also some of the most endangered places have huge populations that would make sinking enough shelters difficult. Depending on the soil composition that might be a short term solution too. The soil surrounding the London Underground is particularly bad for this and it's estimated that 80% of the heat ever generated in the Underground is still there in the walls. https://www.youtube.com/watch?v=hQo6_GkITe0 https://www.youtube.com/watch?v=hQo6_GkITe0

- toiletaccount 5y agoitd make more sense to lay a bunch of pipe underground and cycle air through it. or water in a closed circuit with a heat sink.
- Causality1 5y agoIf you have power you can just use a heat pump like a window unit. This is about places with unreliable or negligible power grid.
- Fordec 5y agoI do wonder, if wet bulb temperature is a function of temperature and humidity (assuming reducing temperature requires electricity usually) will the real trick to reduce mortality will be to reduce relative humidity in a confined space. A supply of emergency desiccants somewhere at home may be an avenue worth exploring.
- jschwartzi 5y agoThis was the original application of Air Conditioning: to reduce the humidity of air inside a building.
- elihu 5y agoI suppose the best available option for a lot of people if designated shelters aren't available would just be to walk to the nearest body of water and climb in, and wade around until the heat subsides.
