I had an interesting idea given that I did not know that this exists and I would love to hear on the feasibility of it from people that know about mining. Anyways, I am building a house in the Florida Keys and I am putting in a 10KW solar array in, given my location it will be fairly efficient, to the point that at most times I will have energy to spare. Now I can pump the energy back into the grid, but I do not believe the return is that great for doing it. So I wonder if I could design a system of GPU's that would utilize the reserve capacity to mine and turn into bit-coins and then turn into hard currency. What variables would I need to know to calculate if it is a more efficient method of capitalizing on the energy? I know I have the sunk cost of the hardware (I am not including the solar hardware because it will be purchased either way). I know I would have to calculate KW to bit-coin creation ratio and then translate that into dollars and then compare that to what the energy company is purchasing spare energy for.
As well, does anyone know if their is any efficient native GPU bit-coin mining software. I found a link talking about a python lib, but is there something written that is closer to the hardware?
