Solar-powered wireless networks on the backs of snapping turtles. I was watching this talk about mola molas, and the lecturer said a big worry was that the expensive transmitter tags wouldn't earn their keep. They transmit data to a satellite about a year after being attached. If the mola dies in the meantime you don't get the data. When the transmitters communicate with each other you've got distributed backups.
