Solar Powered Freezer

Through a group organized at Stanford’s Engineers for a Sustainable World (EWB) chapter our team just finished the first version of a solar powered freezer for the developing world that uses no electricity.

The Solar Adsorption Freezer

The system works through the Carbon-Methanol adsorption cycle, which uses sunlight during the day and low temperatures during the night.  We have taken some great lengths to document the whole procedure, and I have just recently posted a few blog entries on the Stanford Appropriate Technology website we set up. Check it out.
