- semi-extrinsic 9y agoNo, simple thermodynamics ensures us that when no significant mechanical work is being done by the rig acting on the environment, and no significant exchange of mass between the rig and the environment is happening, all net electric energy going into the box will come out again as heat. The reason why mining rigs aren't sold in the space heater aisle is that people usually don't buy $2000 space heaters.
