Ideal for bike riding on windy days.

"Indeed it is. A South-westerly breeze of 4-5 knots for most of the morning, changing to North-westerly in the afternoon and rising as high as 18 knots"
"Do you work in IT by any chance?"-- marklar, Aug 01 2007 Except you can't get directional information out of a Savonius-- BunsenHoneydew, Aug 06 2007 Sure you can. Make it very slightly asymmetrical (like putting a flat tab on one side). Then watch the changes in rotor speed - when the tab is moving downwind, it turns faster, upwind slower. Since wind direction is commonly only reported to sixteen points of the compass, a low-resolution shaft encoder would be sufficient.-- lurch, Aug 06 2007 needs a better title, but a little nerd arrow points you toward the slowly spinning bun i'm giving you. +-- k_sra, Aug 06 2007 Add a small generator and you can power a pair of nose hair trimmers.-- Road Show, Aug 06 2007 Reminds me of a movie I saw years ago. Sean Connery is sailing on the open sea at considerable speed. His companion, probably a jaunty young lady in 60s-style bikini and boufant, inquires about the wind direction. Sean licks a finger and places it in the air. He then points in a direction not entirely dissimilar to the direction in which he is travelling and says, "From over there."-- theleopard, Aug 06 2007 Why not go the whole hog and use a helmet mounted laser anemometer?-- wagster, Aug 06 2007 Because, in the words of the man himself, we must add lightness and simplicate.-- Texticle, Aug 08 2007 random, halfbakery
