For two reasons we are going to power our sound system with a battery. The first reason is the reliability and consistency of a battery. Since one of our goals of the event is to provide high quality entertainment, we want to make sure that the power will not immediately fail even if one of the alternative energy generating sources fails. Also, I feel that by experimenting with a battery, I am modeling how one might use alternative energy in a home. A person may want to use electricity when it is not sunny or windy, or when they are not pedaling a bicycle generator. Therefore, energy storage is an issue. I want to demonstrate that net metering is a way to use the power grid for storage, while disconnecting from the power grid will require a battery for energy storage.
