2006 Re-Energy Solar Oven
Challenge Submission Showcase
Small but mighty, these two groups of re-energy engineers built solar ovens and a wind turbine for this year's challenge.
Eamer's Corners Public School
I chose to build the wind turbine for a science project at school. We were told that we had to do a project on energy and I chose wind energy.
I learned that when the wind blows through the turbine it spins the magnets which charges the magnet wire which causes the LED to light up. When I was finished my project the LED would not light up. I had a teacher from my school look at my turbine and she suggested that I switch my 3/4" magnets for 1" magnets and my rotor from cardboard to light weight fibre wood because the rotor was wobbly. I changed these things and it worked. I was not able to produce enough wind by blowing on the turbine myself - but my mom and dad can.
It was really exciting for me when the LED finally lit up. I was really proud that I was able to build something like this and see it work!!
The Cityfarm Edmonton Harvest Festival
The Cityfarm Edmonton just outside of Edmonton, Alberta recently held their fall harvest celebration. Over 150 participants came to the event and made Solar oven steworganic pizzas, visited chickens, made crafts, listened to music (Back Porch Swing) and made solar ovens. Luckily, the day was filled with sun and the volunteers were able to make four new ovens with families. There were also three demonstration ovens, which were made already and demonstrated how the ovens could cook using only sunlight. With the oven temperatures reaching 350° Fahrenheit, Cityfarm volunteers were able to make a fabulous organic stew from the farm's garden produce, and lots of cookies too. Participants were amazed that a simple oven made from cardboard and tinfoil could get hot enough to actually cook food.
