The Economist with a cool (ha) article on innovation in air conditioning. TL;DR: - Avg temperature already up 1.2°C from pre-industrial baseline, on track to +2°C by mid-century. - AC units to triple by mid-century. - Evidence exists for heat-related mortality avoidance thanks to AC. - AC contributes more CO2 emissions than the airline industry. - Cooling becomes *more* energy intensive per ° as air temperature rises. - Decarbonizing electricity would help, but AC lifespan is typically 20 years, so the energy efficiency of units sold today will impact emissions through mid-century. - AC design currently does two things: cool the air and remove the condensed humidity from around the coils to avoid damage. - Research shows at least 40% improved efficiency by separating those two functions: push humid air through a lattice or membrane that captures water first, then cool the air. https://www.economist.com/science-and-technology/2024/09/04/new-tech-can-make-air-conditioning-less-harmful-to-the-planet

Would be interesting to read a study about the collateral impact AC have on our health. If from one side many life are saved from the heat I have the neat sensation that long term chronic illness are due by the massive use of AC. Btw a sustainable AC is urgently needed.

On my recent Berlin trip, where AC is basically banned, I was brainstorming following question: What if air out of AC was transferred in similar way sewage is, ie. through pipes and far away from upstream environment? There could be optimization and power generation opportunities for all that condensed heat. It would probably dramatically increase deployment costs of AC but it's better than having none of them. Summers in non-AC'd European apts and offices are horrific.

If I’m getting this right, Thoman ACs do more harm than good?

Are you aware of any publicly traded companies working on the next-gen of ACs? :D

this is the kind of thing we need. the mindset necessary to solve or retard global warming. 21st century science isn’t about inventing but reimagining

Interesting research, but where does this lead us According to this, ACs have health benefits as they contribute to heat-related mortality avoidance, but the CO2 emissions is a major hazard that seems uncontrollable Especially when you consider the ACs in large quantity and over a long period of time What do you suggest ?? ACs should be banned ??

I am getting one as soon as I have set up my balcony power plant (small solar panels) so I can make sure I only use the AC when the solar panels produce the energy anyway.

I always said the way the outdoor kept emitting heat can’t be good but I’m no engineer I just enjoy the cold 🌚😂

so you’re AC has been doing more harm to us than good?
