Simplest Power Wing- The Play Sail (plus corrrections)
- Perhaps the most primitive (& quite powerful) kite is the Play Sail. I had been trying to track this concept down under the erroneous name "play wing", with little luck. Thanks to Ray Bohn for setting me straight-==================Also, my previous should have read-The wind actually runs backwards from what it appears.This illusion is due to the fact that global "westerly flow" is in reality rotating east to west with the planet. Sorry!
