Ocean-going robots that could revolutionize fishing, drilling, and science

That's interesting. 70 meters is a pretty dang tall aerial for something with that small a footprint to hold aloft, though. That plan also limits their range of movement severely to keep the network intact, but I guess they could use satellite as a backup.

Maybe a kite of some kind, but how do you reliably launch and retrieve it? I dunno, I think in practice the satellite may be cheaper.

Or a blimp with a thin wire in resonance and two fibers? If you don't need much power, the thing should weigh in at under 50g, which would allow a blimp the size of a large kitchen trashcan (50l).

Disposable paper hot-air balloon for lift, retractable antenna? Or perhaps better yet: disposable paper kite?

Your comment, while I assume you earnestly meant, is enigmatic of the gap between what the lay person may think works at sea and the very harsh and unforgiving reality of the Sea.

Hehe. I left out that I was thinking of a system that used all the environmental monitoring to deploy such a disposable contraption only in calm/good weather - but then it would not be a substitute for satellite data - mote an opportunistic system for bulk backup.

I like the wording of your comment, but I think you mean emblematic instead of enigmatic.

Yes, you're right. That's embarrassing.
