Re: chinese umbrella factory,promotion umbrella,advertisement umbrella - hugh steers - 01-04-2005 i had an idea for umbrellas once. nowdays its mostly too windy for umbrellas. the wind tends to turn them inside out. you see people fighting with their umbrellas in the wind. so why not have an umbrella built like a fan, with overlapping vanes, of course, but angled so that the wind turns the umbrella round like a top. thereād be a pivot at the apex to turn. that way the wind energy would turn the umbrella rather than fight against it. ?
Re: Fanbrella - Paul Brogger - 01-04-2005 . . . and the centrifugal force would shed any rain that might be falling. (Actually, it would throw it on everyone around the holder, but we'll not let that smear the concept.) You may be on to something.
Angle those vanes just right and even Mary Poppins will be interested!
Re: Fanbrella - hugh steers - 01-04-2005 well, i wasnt supposing there'd be a lot of force left to throw it outwards. if so, you could adjust the pivot or turn it into a generator for your calculator - or something.
