Is there a better way to conserve energy to build a solar aircraft that can stay up indefinitely; like the Solar Powered Pathfinder, which could stay aloft for a month at a time only forever? More like a solar powered satellite in the atmosphere. Obviously there would be tremendous value in this.

I propose we add some features to the next rendition of the Pathfinder only this time we build small wires coming out of the leading edge of the wings with bent flared pieces of carbon nano-tube sheets about the sides of a quarter sheet of paper and in a shape which will cause the air to swirl violently and start an eddy vortex or mini-horizontal tornado over the wing. Each flared piece will be coated with a heat collecting type coating, which will stay hot from the sun and thus heat the air as it creates the vortex eddy.

I propose we make hundreds of these on each wing. Each unit will stick out from the front of leading edge of the wing about 16 inches and start from about one-quarter way of the top of the leading edge
