The “thermally elastic” alloy, which is supported by a $500,000 grant from the US Department of Energy, works like a traditional compressor-based system, but uses far less energy. The University of Maryland team explains,"The approach is expected to increase cooling efficiency 175 percent, reduce U.S. carbon dioxide emissions by 250 million metric tons per year, and replace liquid refrigerants that can cause environmental degradation in their own right."

Wow! How fantastic would that be. I got my electricity bill in today and for the first time in a month I broke out in a cold sweat LOL.
I hear ya! I always dread mine dropping in the mailbox. We do our best to keep the AC where we're as comfortable as needed without it costing a fortune. It's hard to balance it all out. Hope that metal is a reality soon.

I'm being very careful with mine this year. I even set the timer on my stove to remind me every hour to think about it. I let it run and run sometimes when it could be turned up a degree or two. Now I stop and think "am I comfortable where the temperature's at right now?"
If all I save is a few hours a day, it will soon mount up.
