Heart Sail - YouTube
I always wanted to have a sail in my yard and after a few years of hemming and hawing I hit upon this idea. Build like a regular sail but made out of ironed together plastic table cloths, bamboo and rope
. The light above is a solar
yard light attached to a pinwheel. The LED is attached to one of the tips. The whole thing sticks in a tube in the ground and weather
cocks nicely. You never have to guess which way the wind
blows and the speed. It's been working for six months and is still ticking.
