The Next Idea
So many innovative ideas begin with inventors observing simple events. Take Newton’s falling apple, for example, or Archimedes’ overflowing bathtub.
For Emil Ureel of West Michigan, it was building an ice rink in his backyard — or rather designing a refrigeration system to keep it from melting.
“I thermodynamically ended up producing a chiller system from a used central air unit,” Ureel said. “Going through the process, I learned something related to thermodynamics that’s referred to as saturation vapor pressure.”
