Design of a Vertical Wind Turbine to Power LED Street Lights Design Team Juan Berrocal, Paul Cabral Brian Dolan, Michael Tangredi Design Advisor Professor Taslim Abstract Wind turbines and street lights are two expensive free standing structures which can benefit from each other. The light poles are similar to the poles used to place wind turbines in the air. A design to attach a wind turbine to an existing light pole to help power the light would be an environmentally friendly way to reduce costs of powering a street light. The turbine should be small, weighing around 50 pounds. The production cost of the turbine is intended to be below $1000. The turbine will use net metering to the grid to store the energy rather than storing it in a battery. The turbine will be 1 meter in diameter and 1.5 meters in height to reach the requirements it must satisfy. It will have two arms that clamp to existing light posts. The cut in wind speed for the turbine will be 2 m/s while spinning at 150 rotations per minute. At the optimal level, the turbine will be able to produce 50% of the wattage to power an LED street light saving the government around $100 per street light per year.

The Need for Project The growth of green energy The proposed idea for a wind turbine attaching to existing light has opened a market for posts will allow cities to cut back on wattage used, at a low cost. efficient wind turbines.
