I found this article interesting. A super computer in every home and to use the heat that dissipates from it to heat your home is very smart. I wonder how many inventors are thinking of multipurpose appliances when creating products. The smart manufactures should try to differentiate themselves from competition this way.
Now I am curious to see if anything is ready. I am in the market for a new furnace in a couple years. I would love to try a prototype out. Even if its on a small scale and could supplement your heating needs. I think it would be worth checking out. The source of my excitement for this topic came from Gizmag. The original article is here.
