Lots of people are interested in tracking and billing electricity use. Think landlords, RV camping lots, motel rooms, etc.

All it takes is a couple tenants plugging in an ASIC on "free power" to make the landlord start billing for usage.

It doesn't require sats to do this, but for machine-to-machine settlement, sats can't be beat.

Value for value. In the current model, the customers that use little to no electricity are paying for the "free electricity" used by those who exploit it or use it heavily.
