Cone shaped cups are mounted on 3 horizontal rods connected to a vertical shaft

The shaft goes through a hollow cylinder with copper wire wrapped around the inside of the cylinder

In the middle of this cylinder connected to the shaft are two magnets

Mechanical AspectsMechanical Aspects The cone shaped cups attached to

horizontal rods catch the wind energy that in turn spins the vertical shaft creating mechanical energy

The vertical shaft is passed through the cylinder which is held in place by wooden supports to eliminate wasted energy

Electrical AspectsElectrical Aspects There are two spinning

magnets, whose north-south pole rotation inside a copper coil creates an alternating current.

This current flows through the two wires at the end of the coil to light the LED bulb.

Efficiency CalculationsEfficiency Calculations

Our theoretical power output is calculated as follows:

P = .5 x rho(air density) x A(rotor area) x V(wind speed) = .2603 W

E(efficiency) = P / [(.5)(rho)(V^3) = .25 or 25% efficient

Design/Construction IssuesDesign/Construction Issues First used regular copper wire coil that didn’t

produce much voltage at all, so we got magnetic wire and saw immediate results

We ordered very powerful magnets that got lost in the shipping process, so we just purchased some extra-strength magnets

ConclusionsConclusions The best way to construct something is

to make alterations while building it instead of deciding on the perfect design

We had to do a good amount of research concerning generators and how they worked

If your teammates schedules conflict divide up the work
