Wind energy for outdoor lighting. Final report
This project was an attempt to develop a wind energy device which could be mounted on existing light poles and which would provide sufficient electricity to power a light on such poles. It was to be of design and materials simple enough to warrant ease and economy of manufacture. The original design was modified several times during fabrication in order to respond to the peculiarity of various types of materials involved. The system of belts and pulleys originally proposed proved too limited by friction to be practical. The final prototype was of sheet galvanized steel in three cuts of only three simple shapes. It was mounted on a recycled rear wheel axle of a 3/4 ton truck with axis vertical. A large pulley transferred energy to an automobile type alternator through a V-belt. The spinner turns easily in light winds, but even in moderate winds does not turn sufficiently fast to provide the necessary 400 rpm in the alternator. A larger pulley produces proportionately more drag, limiting rpm at the alternator. We now have an intriguing - some say beautiful - device which is enjoyed by passersby as kinetic art, but which unfortunately does not produce electricity. The concept may yet prove feasible, perhaps in a location of higher wind velocity, and perhaps with a larger diameter spinner. But as a simple, universal design of widespread application, it has not proved practical.
