The future of air conditioning?

 When we were grad students in Chapel Hill, we lived in married student apartments. There was no central air. We ended up using a 5000 BTU window unit in tandem with a dehumidifier. The dehumidifier easily pulled a gallon or more of water out of the air each day, which allowed the air conditioner to keep up.

Near the end of our time in Chapel Hill, we bought our first car, a baseline Mazda GLC. It had no air conditioning. We owned that car for about 15 years before it rusted out, but it was broiling hot in the summer.

When we bought our little home on the prairie, air conditioning was two 20,000 BTU window units, one in the dining room on the ground floor and one in the master bedroom. They were horrifically noisy and there were hot and cold spots throughout the house.

Eventually, we got central air, which is whisper quiet, and with the addition of rooftop solar, isn't that expensive. But even in the Northeast, where we're looking to move soon, air conditioning is no longer a luxury.

Don't know if this is the future of air conditioning, but anything to increase efficiency and save electricity would be welcome. https://bigthink.com/technology-innovation/air-conditioning?utm_source=mailchimp&utm_medium=email&utm_campaign=weeklynewsletter&fbclid=IwAR1w74g-_sDSooqSRnzhuMhk1UQZJ0hLXSxYGJt_rMtkOVzEOBmOD08CgN0
