How much of Qatar’s 2°C increase is due to urban heat island and how much is believed to be climate change? TFA says it’s a combination of both but does not elaborate. I was thinking why not just mist water, but with the high humidity that’s not going to work. Sounds like a good market for personal cooling devices. Cooling certain areas of the skin like your wrists is good at helping shift the apparent ambient temperature. Much more efficient than cooling the streets. There are also those devices you can wear around your neck. I also wouldn’t be surprised if it was possible to create a specially insulated shirt that has a personal chiller (perhaps backpack size) piping cool air down your back to bring down core temperature. 200Wh in a 1kg battery can probably provide a decent amount of personal cooling, particularly if it’s built to interface intelligently with specialty clothing using performance fabrics. You need a system than can intelligently disperse the heat in a compact format, even in 50°C ambient, which is probably the hardest part. It’s not like this place wasn’t always blisteringly hot, if you live in the desert you’re going to want good tech to stay cool.
