The parabolic mirrors concentrate the rays of the sun to produce high temperatures needed for cooking. These do not require any fuel and have zero emissions.
Cook day or night, indoors or out. The only stove that stores sun’s energy as thermal energy.
COOK WITH The Sun, Even At Night.
Heating: Sun Buckets are heated with concentrated sunlight using a parabolic reflector dish. Heating nominally requires 2 hours, with the exact time varying depending on conditions.
Storing: After heating the Sun Bucket to 350 C, it is removed from the heating system and covered. Sun Buckets are fully insulated and the outer shell is cool to the touch. Energy can be stored for several hours, allowing collection of energy during the day that can be used for cooking that evening. Sun Buckets, Inc. is also developing longer-term storage innovations to enable storage for use on cloudy days, and even during lengthy rainy seasons. We ultimately aim to provide energy year-round in most locations.
Cooking: When one is ready to cook, they simply remove the cover, and use the cooktop, like with any other stove. Sun Buckets facilitate nearly every cooking style in ways that mimic traditional cooking customs and the use of fire. One can cook for 1-2 hours, depending upon the level of energy demanded by the cooking task. For larger quantities of food, two or more Sun Buckets may be needed.
Energy transfers as heat into the sealed bucket. After the inside is hot, the container is removed from the collection system and the insulated cover is replaced. The outside is cool to the touch, even when the inside is 400oC. To cook, the cover is removed, and the circular face is used as a cooking surface, like a hot plate or heating element on a stove or in an oven. There is no electricity, batteries, electronics, or moving parts.
