Lack of access to viable, life-saving vaccines is a major public health problem worldwide. Our project objective is to create a feasible, frugal, and environmentally conscious transportation solution for vaccines. Our design for a bicycle-powered refrigeration system can function in both urban environments and rural areas with unreliable electricity and minimal infrastructure. This is enabled by integrating power generation from bicycle kinetic energy, thermoelectric cooling, voltage regulation, temperature control, and heat dissipation subsystems. The system is enclosed in solid housing to protect fragile vials against bumps and crashes and can be adapted to fit onto existing bicycle racks.
