We got out the bike blender in garden class so students could whip up pesto without electricity. Kinetic energy is a way of the future. No better place than garden class to think about kinetic energy and how harnessing the "free" power of movement could help our Earth.
Students were sold as soon as they saw the bike and its basic blender mechanism. The tire rubs against and turns a grooved rod the diameter of an adult thumb. The grooved rod is attached to the mechanism that spins the blade of the blender so puree speed is dependant on pedaling speed. Kids couldn't wait to start blending!
We harvested basil, mint, parsley, and spinach (some even requested raw kale) fresh from the garden. Gardeners washed the herbs, loaded them into the blender, and added other pesto ingredients. Potential pedalers lined up in three seconds flat; the only problem was the size of the mountain bike the blender boot was set-up on. The littlest children had to stand up to reach both pedals while dodging the middle bike bar in order to extend their legs. Needless to say, the longest-legged children produced the smoothest pesto. No one gave up and most were eager to try. All were fasinated to see personal power transformed into a petroleum-free blending machine. The pesto was da bomb. Every bite gobbled up by glistening children.
I coould see intelectual light bulbs above the heads of pedal powered pesto makers all day long. Years ago, I heard about a charter school in Colorado that powers its computer lab with bike-powered generators. Students must sign up for pedal duty to help maintain continued computer usage. Just last month, I viewed an artist's sketch of dreamed-up electricty producing scenarios of the future. One depicted a playgroud covered by a magical surface that traps kinetic energy and delivers it to a system that illuminates the playground's neighboring buildings. So children playing tag or bouncing in the castle would produce electricity for their own city blocks.
Anyone know where we can get a pedal-powered garden stove?
