what is it, what is it???
I sit by my computer pretty much a lot and do programming mostly.
In any case, I remember an old friend of mine about 3 years ago came up
with a neat way to keep feet warm, I thought at the time he was smart for
thinking it up. Lately as I get older, I noticed that my feet also are constantly
cold, so what to do. I could buy a small foot warmer, but the problem with them is that they run all the time, and really waste the energy, and I would have to buy it...
What your looking at is a cement block about 2 to 2.5 inches thick and about 1 x 1 ft wide. embedded in the cement is a 500 watt stove element. I made up some cement, found a cardboard box, laid a little bit of styro down for support, then poured about 1 inch of cement in, next I cut up some coat hanger wire and layer them across for more support, and laid the heater on top of that. Then filled the rest up with more cement about an inch or so. let dry for one week. Solder wires to a cord and heat it up, then let cool, do this a couple times to get the mosture out.
Does it work well... OHHHH YEA!! Nice and warm in a blanket for about one hour before another preheat, which takes about 3-4 mins of heat. Done..
So very efficient I think, so do my feet.
