Sell the S1 to someone with free or cheap electricity. There is no way with regular electricity it makes sense to run a S1.
Better yet get yourself an extension cord then plug it in a public establishment, or bring it in your office and mine there.
At least thats what Im doing with my old miners.

In a lot of cases this would cause loss of job. Bringing in unauthorized equipment in a lot of places is a no-no.
I'm not sure what type of place you work in but normally these outside devices scare companies. And they will want to keep them off of the network.
