Abstract

The main goal of the Renewable Energy Efficiency Demonstration senior design group is to design, test, and build solar and wind powered modules that display the operation of renewable energy. The base of the display unit consists of two flat rectangular wooden boxes. This wooden base has removable drawers, which allow for storage of electrical circuitry of the project. A plexi-glass enclosure is attached to each base to protect each module's components from damage during transportation. The enclosure also protects your audience members from injury caused by moving paiis. The modules are each separable from one another to allow easy transportability.

The solar module consists of two halogen light bulbs located a distance of 10 inches from the solar panel. The solar panel is attached in a way to allow for rotation of the panel about a horizontal axis. This varies the output of power from the solar module.

The wind module consists of an 18 inch diameter fan positioned 6 inches from a 3 bladed wind rotor. This wind rotor is connected to a DC motor and the motor is run in reverse to act like a generator, thereby producing power. The wind rotor is positioned so as to allow for rotation about a ve1iical axis. This varies the output of power from the wind module.

The solar and wind module power outputs connect to separate entertainment devices. The solar module powers an electric racecar that travels along a 32 inch long figure eight racetrack. One car is directly powered by the solar panel, while two D-size batteries power another car. This enables the demonstration of a change in power output as the panel is tilted since the solar powered car speeds up and slows down as the panel is tilted. The wind module powers a spinning illusion-producing disk. This disk is connected to a DC motor whose rotational speed varies depending on the orientation of the wind rotor with respect to the fan. This enables the demonstration of a change in power output as the rotor is tilted with respect to wind direction.

The total budget for this project is $850.
