Imagine that you decide to live completely off the grid. You commit to limiting your use of electricity to what you can create using a bicycle generator. The generator works by rotating a circular coil of radius 5 cm in a permanent magnetic field of 0.5 T. The wire coil has 25 turns. The EMF induced when you pedal the bicycle at what your best angular velocity is used as a voltage to charge a set of batteries.

Using your best guess for how fast you could pedal, on and off, for a full week, what is the best case scenario for how much electricity you can create? Think about losses due to things like internal resistance of your batteries. What simple modifications could you make to the generator in order to improve its performance?

In your responses to classmates, compare your calculations. Who has the best chance at living successfully off the grid and why? Can you help a classmate improve their energy output and storage?
