GoSun's patented solar cooking technology the most reliable there is. As long as you have a bit of sunshine, you're in business. The vacuum insulated cooking chamber captures a broad range of radiation, including ultraviolet, meaning even a light over cast won't stand in your way.!
Sunlight is focused by the compound parabolic reflectors onto the tube, heating the inner cooking chamber. The vacuum tube acts as a near-perfect insulator, converting more than 80% of the Sun's rays into useable heat. The heat inside mimics that of an oven, building up to a staggering 550°F/ 280°C!
