Future of keeping warm

I was thinking about buying an electric blanket to warm up the bed on really cold nights, and upon searching the internet, I came across a new technology that I simply must share. They are little rubbery discs, the size of a Frisbee made by Snuggle Safe. You heat them up in the microwave for 5 minutes, and they hold 100 degree heat for 12 hours! After that, they slowly cool down to room temperature. They are currently made for pet beds, but I am very excited about this. I am sure they will develop the technology more to be used in a larger scale in the future. I have heard of several people using them in their chicken coops to keep the hens warm, and with other outdoor livestock. It can even be used in the car.

There are no cords, so the uses are limitless.
