I am designing a bicycle that can generate electricity for a science project at school.
My design incorporates a flywheel. You see, flywheels are used in cars. In essence, these are regular wheels, just heavier. This added weight adds inertia to the wheel, thus keeping in going even if no energy is being inputted. In terms of cars, the alternator is powered this way.
I am replacing the back wheel of my bike with a flywheel, which I can thus use to potentially generate electricity. The more weight I add, the more inertia the wheel has and the more electricity can be created over a period of time.
Based on my calculations, if I choose an appropriate wheel I can get to very high RPM's using pulleys, sprockets, gearboxes, and other engineering mechanical ideas. The bicycle will be stationary, so I won't be going anywhere. It will be designed in such a way that I can pedal and the wheels will move, but I won't go anywhere. Exactly what I need.
One tradeoff however. I cannot make the wheel so heavy that I cannot pedal efficiently. I need the wheel to be the heaviest it can be without it being so heavy that I cannot push it and get it going.
I am a relatively strong, fit, male sixteen year old. I participate in many sports, such as football and basketball and soccer. I am 5'11" and I run everyday.
What weight should the wheel be?
