Perpetual Kite Materials Engineering
Large-scale AWES kites might have a very long
service life. We know that large UHMWPE cables capable of mechanically
transmitting many megawatts can last decades in service if protected by
known means (chafing gear (sleeves), coatings, etc.). A giant soft-kite
load-path network can be made of this stuff and be relied on to survive
The problem is the infill membrane, which in the current state of the art
will "only" last about 15,000 hr in normal high-duty use. It should be
practical to adhesively laminate new layers as old ones degrade,
periodically exfoliating old membrane from one surface as the other
surface is renewed. Many options exist as to the number and composition of
sandwich layers, and how to adhere and ablate them.
This is a simple skin-like biomimetic method. One can even imagine an
immortal bamboo and paper kite, always repaired and renewed, lasting

- Proposed: Live blossoming vine that has a good L/D blossom; the
living vine roots in soil; the vine has a main trunking tether up to the
perpetual blossom; the DNA and structure of the blossom gives bladder
chambers for LTA shaped bulbs in the wing set. The vine is
alive and reacts with sun, air, and soil to live and self-repair during
the year. The living AWES produces fruit and sugars; worn parts are
composted (methane obtained). Don't all say "tree" all at once.
