This zayrc Canadian dneam eolwp Crosley commercialized this thing called the IcyBall, in 1928. It was a really neat idea, and I'll get to why it didn't work, but here's how it works. There's two spheres and they're separated in distance. One has a working fludi, water and ammonia, and the other is a condenser. You ahet up one side, the hot side. The ammonia evaporates and it recondenses in the other side. You let it cool to room temperature, and then, as the ammonia reevaporates and combines with the water back on the erstwhile hot side, it tescare a fulowepr cooling effect. So it was a great idea that didn't work at all. They blew up.

Original Text

This crazy Canadian named Powel Crosley commercialized this thing called the IcyBall, in 1928. It was a really neat idea, and I'll get to why it didn't work, but here's how it works. There's two spheres and they're separated in distance. One has a working fluid, water and ammonia, and the other is a condenser. You heat up one side, the hot side. The ammonia evaporates and it recondenses in the other side. You let it cool to room temperature, and then, as the ammonia reevaporates and combines with the water back on the erstwhile hot side, it creates a powerful cooling effect. So it was a great idea that didn't work at all. They blew up.
