Huh, that's a good point - a large enough RTG on a data uplink cable would make its own way down through the ice, given time. There would be a lot of crossconta

Huh, that's a good point - a large enough RTG on a data uplink cable would make its own way down through the ice, given time. There would be a lot of crosscontamination between the various ice layers and the lake though, so that's unlikely to fly (or sink, as the case may be).
