Ridiculously impressive and extremely hard to shield against, baring using your computer in a faraday cage.

Thinking about it, is there any way to vary the electricity consumption of the computer as to transmit that way if it was in such a cage?

Computer enclosure and server rack manufacturers might have a new market for built-in Faraday cages.

It should be possible to vary the sleep states of the processor, at least if you are root. That should give you something like 50 W amplitude. No idea how that would look on the other side of the power supply.

It's pretty obvious, but perhaps worth noting that this requires the malware be installed on the computer somehow. That in itself is probably a challenge for an air gapped computer.

Not if you access to the supply chain for the construction of the computer.
