  Wow. Imagine just having a tether like this [whatever altitude] above your property - if you had multiple of these fibers, one could use them as guy-wires - to hold a balloon with solar powered cam and redundant fiber connections... These should be placed over mountains - remote cabins, ski resorts. Whats the tensile strength? So if you do use them as a guy - and hit some heavy winds... Put high powered air-plane-warning LEDS... a cam, and a HAM-to-fiber transceiver... EDIT - Also, several strands of these as guys holding a solar cambloon in place would pose no substantial threat to Big Bird.

    > Whats the tensile strength? About 600 Kpsi. That works out to somewhere around 0.1 lb per strand.

      Oh I was thinking that the thing was jacketed like... I just assumed wrong - youd still need to wrap it in superconductive carbon nanotubes to make it work. :-)

  For context, the total mass of a standard M67 fragmentation grenade is ~400g, including a 180g of actual explosive. So this is like a third of the standard payload of the e.g. DJI drones dropping grenades onto foxholes. My initial expectation was that the cable would upset their mass budget, but honestly, that's pretty minor as these things go. Certainly, bigger boom > smaller boom, but smaller boom >> incomplete boom mission.

  >.014 kg/km Just post it in grams, ugh. (14g/km) >or 0.14kg for 10km (or 140g for 10km)
