<p>Team 7 </p><p>Problem statement: Our project consists of designing and building a perpetual motion device that drives an electric motor and creates a measureable amount of electricity. </p><p>Project plan: Our design consists of lightweight disc with magnets attached to the outer edge. The disc will be mounted to a DC motor, which will provide current to an LED once the disc starts creating torque. We will have two designs built into one to test whether the disc can be driven without a power source. If we are unable to create a sustainable force without outside power, we will demonstrate how outside power could generate a positive force. Our design will be environmentally friendly and use a number of recycled materials.</p><p>Circuit View Lateral View</p><p>Materials cost:</p><p>Unit Description Source Quantity Cost Total Cost http://www.digikey.com/scripts/D kSearch/dksus.dll?
