Thanks videos on you tube |
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. Thoughts REPLACE THIS WITH YOUR THOUGHTS: HOW COULD YOUR WINDMILL BE IMPROVED, HOW COULD THE EXPERIMENT BE IMPROVED, IS 100% EFFICIENCY ENERGY TRANSFER REALISTIC, WHAT WOULD YOU ASK AN EXPERT, HOW CAN TECHNOLOGY SUPPORT SCIENCE TEACHING AND LEARNING, ETC... |
