The most cookies baked in one hour using solar ovens is 1,225, achieved by Miami Country Day School (USA), in Miami, Florida, USA, on 20 April 2012.
The cookies were cooked by students, parents and teachers in an event organized by student Matthew Cohen to honor Earth Day. The cookies were donated to the Feeding South Florida food bank and the ovens were donated to Help Brings Hope to Haiti. Fifty Global Sun Ovens® and two Villager Sun Ovens® were used to bake the cookies. Photos: https://powerfromthesun.us/
