No Stinkin' Gearboxes- Tri-Tether as Power Up/Down Converter
- Cooperative IP DisclosureA Tri-Tether is rigged such that two legs, A & B, are set out almost in-line. The third leg, C, runs out orthogonal to AB. Tensioning between AB pulls on C at a higher speed with longer travel, effectively performing the function of an amplifier, transformer, or gearbox.Gearboxes have always been an expensive & vulnerable part of power mechanics. Improved HAWTs are converging on gearless designs with large annular diameter generators that generate usefully at low rpm. John Borsheim of ATEC & KLD, partners with KiteLab in Austin, are leaders in this movement.The Tri-Tether Power Converter helps bridge the gap between slow cheap kite power & gearless generation velocities. Its minimal rigid structure is the ground itself; small anchors & pulleys are the only hardware required. It runs both ways & can be cascaded, is vastly cheaper & lighter than gearboxes & so is inherently flyable or could be nicely strung over valleys or off structures.KRKR
