A solar cooker is a device which uses the energy of direct to heat, cook or pasteurise drink. Many solar cookers currently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves,and advanced, large-scale solar cookers can cook for hundreds of people. Because they use no fuel and cost nothing to operate, TGIIF promotes Solar Cookers as rural people have no capacity to buy gas, but cut trees and cook their food.
