Wouldn't it be easy to verify it was a fake by the amount of power it was drawing off the grid?
Just put peroxide in the cooling fluid. It will make heat, and no hidden wires or grid draw.
Sure, if you know what meter to read. :-)
Let me think... my understanding is that a home needs ~4 kilowatts, give or take. So 1 MW draw would be equivalent to the power requirements for a couple hundred houses. Or perhaps equivalent to a middling-sized industrial facility. Drawing that amount of power without anyone noticing might be difficult but not impossible. Can anyone with experience in this area comment on that?
