Radially Pumped Isotropic Kite

An isotropic membrane kite wing (think "triangular playsail") anchored by a radial array of winches (minimum of three) can be sustained in flight by phased tugs in zero wind. The iso membrane does not itself rotate direction but merely changes which way is "front" as it orbits over the center-point. To generate power the membrane shunts back & forth crosswind, driving winches in generator mode. Earlier proposed iso methods involved many rotating kite cells or distributed AoA actuation. This new simpler method promises to scale even more at lower unit-energy cost.
