How kites and flags may harvest wind power - press

Note: while flags as such are not optimal WECS, they prove the principle of passive self-oscillation dynamics (dynamic stability) that has been developed as “FlipWing” wingmills by KiteLab Group and kPower, as high-AR power wings that self-flap powerfully, in pumping strokes. So its not too far out to accept the energy flag idea in its optimized flipwing form.

Note also that piezo material wants to oscillate at >10kHz for efficiency, but ordinary flags don’t come close. Flipwings directly drive mechanical pumping to a groundgen, a far more efficient WECS basis.

See Old Forum archives and Energy Kite Systems for years of documentation.

Ordinary flags reliably flap but are unsuited to harvest energy. Here is a FlipWing flapping demo showing high power-to-mass and power-to-cost-

Cool working demo.
Love a bit of cheap tech.
Nasty action though.
Can’t imagine it’s very efficient, or could be supported without a lot of effort and wear.
