Transform any old cooler into a solar-powered AC unit
So winter may be in full effect for a few parts of the world, while others are still trying to just chill out. I am talking to you San Juan! This fun DIY came to us by YouTube user DesertSun02 (very appropriate name) who aims to create instruments that are solar power friendly. We here at IE can definitely get behind a cause like this, especially when an AC unit can really tear a hole in your energy bill.
Items needed for this DIY are all very simple and easy to gather, starting off with that old cooler that you have not used in YEARS.
