Awesome post, I really like the idea of finding functional uses for the heat produced by mining!

My father and I have started a little side project here in the UK where we want to set up a rig to heat our greenhouse during the colder months of the year. Until we discovered the great opportunity that mining presents for subsidising heating costs, we could only dream of finding an economically viable way to grow food year round. The longer-term vision is to have a wind turbine can power the rig, but one step at a time I guess!
