We're actually not heating the building with waste heat, the second prototype unit is being designed to be the primary heat and eventually cooling for the building, the computation is just a beneficial byproduct of creating heat for those existing loads.

When you think about processors and where all the energy goes in running one, it's all heat.  An infinitesimally small amount of energy is consumed in the actual processing, likely couldn't measure it is you wanted to, and the main output of computing is heat.  If 99.99999% of the energy that is consumed by a processor is converted to heat then it is pretty efficient at making heat out of electricity, at least as good as the existing resistance heating technology today.

The big difference is the beneficial byproduct - computation.  We are using computation to offset energy consumption that already exists (people already pay to heat their house and water) with a heating system that makes hot water and air with computation.  That means you are getting one or the other for free, computation or heat.  If you are actually making money off of the computation (by mining coins?) then you could, in theory, be making money while heating your house or hot water.  I dont think you can do that with a heat pump... yet.

We are already hitting temperatures with the 1st prototype that allow us to create cold with heat as well so we will soon be making heat, cold (for AC or refrigeration) and computation all from the very same energy we are just using for computation today.

Its pretty cool, or hot depending on how you look at it.
