Solar Powered Fridge Princeton EPICS Project

Each year, 3 million people from developing countries die from diseases that could have been prevented with a vaccine. Vaccines need to remain between 2 and 8 degrees celsius to retain their immunization effectiveness, and many countries do not have the infrastructure and electricity availability to support this requirement.

 

This is where solar powered vaccine fridges come into play. Solar power serves as a replacement for grid electricity, and can serve as a patch in the cold chain when grid electricity is not available. The invention of direct drive solar fridges have increased the popularity of solar power, but we want to build a passive solar adsorption fridge, which requires less maintenance than a direct drive fridge.
