Our Design Madonna design, Made of paper plates, it evolved into a multi-cup design with 4 cups in the end. Our Experiment initial mA readings were 0.37, 0.45, 0.2, 0.4 but later we got the following Results Reading 1 Current [ 5.6] mA Reading 2 Current [ 5.2] mA Reading 3 Current [ 5.8] mA Reading 4 Current [ 5.2] mA Average Current = [ 5.4] mA Windspeed at fan = [ 4.7 ] ms-1 Resistance = [100 ] Ohms Power = I * I * R (remember to convert mA to A) = 0.00291 Watts So with a windspeed of [4.7 ] our turbine generates an average current of [5.4 ] mA delivering [2.91] mW per second so in 10 minutes it could generate [2.91 * 600 ] mW. = 1746 mW If playing music on an iPod classic consumes about 77mW per second, 10 minutes of turbine time (assuming 100% energy transfer efficiency) can power [ 1746/77 = 22.67 ] seconds of playback time, enough to listen to about [ 0.126 ] 3 minute songs. Thoughts Why do wind turbines need to be so big to generate decent amounts of energy? |

Many thanks to all of you who participated in our Brighton Science Festival - DIY Energy experiment held as part of the Family Day at Hove Park School. You should now be able to find your experiment id scrolling down the righthand column of this page. You can see photos of the windmills on flickr and study a table of results here. (If you find a photo of your windmill badly labelled please add a comment in flickr) Remember we have more DIY Energy events in March!

Our Design REPLACE WITH WORDS ABOUT YOUR WINDMILL DESIGN Our Experiment REPLACE WITH DESCRIPTION OF YOUR EXPERIMENT Results EDIT WITH YOUR VALUES Reading 1 Current [17.2 ] mA Reading 2 Current [ 17.5] mA Reading 3 Current [ 16.9] mA Reading 4 Current [ 17.2] mA Average Current = [17.2] mA Windspeed at fan = [6 ] ms-1 Resistance = [100] Ohms Power = I * I * R (remember to convert mA to A) 29.58 So with a windspeed of [s ] our turbine generates an average current of [I ] mA delivering [P ] (convert W to mW) mW per second so in 10 minutes it could generate [P * 600 ] mW. If playing music on an iPod classic consumes about 77mW per second, 10 minutes of turbine time (assuming 100% energy transfer efficiency) can power [ 230.5] seconds of playback time, enough to listen to about [ 1.3 ] 3 minute songs.
