@netspooky@haunted.computer It's a bit funny that in their paper they talk about EMI as a side channel, which would only work across short distances. What we showed in our paper (through simulation) is that if you have access to a big enough load like this, modulating it properly you can broadcast information across the whole continent. If your load is smaller, using local phase variations I'd guess you could still broadcast across a few hundred km radius without much trouble.
