Have you ever wondered how you can buy apples in the store in wintertime when you know apples ripen in the summer? How can that be?

Refrigeration Simplified

I was relaxing with a friend discussing the week we had, and I mentioned my examination of a facility with a pretty sophisticated refrigeration system that had some issues. My friend said he didn’t know anything about refrigeration and did not want to know, but being a good friend, he listened...

Hydroelectric Dams
