Lightweight, safe, high speed, high flying windmill idea


The biggest problem I see with wind power is that A) the wind is way up there in the air and gets (much) slower as you approach the ground B) anything that you lift way up into that good wind can fall / fly a long way and C) if it is heavy, it's going to do a lot of damage when it hits the ground.

So I'm more interested in windmills that use light-weight cloth type materials. See my low and slow sail based mill

I've been turning over in my mind a sort of dirigible with sail "wings" that would be turned about its axis by the sails and use a mooring line looped over a pulley at the nose. It would pull up on one side of the line and let out the other. On the ground, the pull up side of the line would turn a pulley on a generator. The "let out" side of the mooring line would run over a pulley some distance from the generator side which would be spring loaded to maintain tension on the loop.

The killer on that design is how you keep the thing from turning in the air and tangling the lines, while at the same time allowing it to turn into the wind.

Robotics nuts!

Check out http://users.frii.com/dlc/robotics/projects/botproj.htm from Dennis Clark. This guy ROCKS! He has made (and sells but also releases code, docs, etc...) for a number of cool little robotic modules including whiskers, IR proximity detect and remote control, Sonar proximity detect, PWM, Servo, compass. Most of these use the little PIC 12C508 controller which costs basically nothing and is soooo tiny.
The 4 servos, 2400 baud serial servo controller is a wonder of magic and he sells the programmed chip for $8. Wow!
