Week 1: Proposal, Timeline & Budget


What are we building?

We are planning to build a bicycle generator. This will involve someone pedaling on a bicycle to power any electric device such as your cellphone or the battery packs in this classroom.

Why are we building this?

We want to leave the classroom with something that can be used for future generations as well as a way to create human powered energy that is sustainable while promoting physical fitness.
