SOLAR COOKER

Using an insulated solar electric cooking technology, developed in 2015 by Cal Poly's Engineering and Physics department, we connect a solar electric panel directly to an electrical heating element, which cooks food. We use diodes as our heating element and we insulate them with JB Weld glue so the low power (~ 100 W, 22 V) system costing less than $100 can slow cook a family’s meal in several hours. We use a diode chain instead of a resistive heater because this allows us to utilize solar electricity to its maximum efficiency regardless of the time of the day.
