If your professor is waxing theoreticals, then sure. Almost anything is possible if you have the right set of circumstances. Heck, if your power supply had a weird transformer, and you could modulate the frequency and voltage, it might generate a low level transmission compatible with wireless, Bluetooth, etc, etc. Of course, why not just light surge the power supply, force them to get it fixed, then gain physical access to the system then?
