chatter or natural infrastructure

The quietly superb BLDG BLOG has an excellent back-to-back series of articles on early improvisations and alternatives to telephony and wireless communications technology that patched together networks from features of native landscapes, including party lines with barbed-wire carriers across the Old West that was really a ranchpunk bit of cleverness, and serious proposals for a massive antenna array in the Wisconsin Dells (plus a bonus Soviet Dooms Day device) or Antarctica to facilitate correspondence with trawling submarines with the bedrock of the Earth acting as a transmitter for a Cold War worse-case scenario.
The series began, however, with an article from a science magazine on accidental discovery that a tall and living tree-trunk makes a surprisingly good aerial, complete with schematics and scheming. These were really engrossing stories and rather the opposite of leapfrogging technologies in their ingenuity. A tree, even if ill-used, is a far better sight than a cellular tower any day, and it would be really keen if the same creativity could rig hill and valley or derelict pathways to harness, passively, energy.
