Close guess - rocket engines are so loud that launch pads and test stands almost always need a water deluge system to stop them from self-destructing. If you have enough water in the way, the energy from the sound waves gets dissipated to a more reasonable (but still probably fatal) level.

    Or it's insulated but over time I guess the sun would damage the plastic and air/water would start to get into the wire and corrode it?

    Bingo! Ripped out a bunch of it yesterday and found a section of it where insulation has failed for whatever reason and the wire was crumbling to dust.

    Nothing special, any copper wire should work.

    It uses induction - the base station sends a signal around the loop and the mower picks it up with a coil. The signal is inverted when the coil is on the outside of the loop.

    Hopefully will find enough time (and nice weather) to fix the robotic mower's boundary wire. And by fix I mean rip the whole lot out and replace with the heavy duty wire. It's done well to last so long, but it's in too poor condition now for me to bother trying to patch whichever section is corroded.

    Then I have to put my fancy new Old Man Mountain front rack on my bicycle and figure out how to mount my light to it.

    I did the same except I did the lazy way for idiots: added a cheap USB network adapter to Home Assistant and connected that to a separate network switch. Reolink cameras have been rock solid and haven't complained about being air gapped from the internet.
