The portable cooker GoSun needs no electricity, no fuel, no charcoal, and not even open flames to cook a meal.
The gadget is powered entirely by the sun and can cook an entire meal in mere 10 minutes or less. GoSun’s cooking temperature can quickly be adjusted from 200°F (93°C) to maximum 550°F (288°C). It can heat water or prepare fresh meals even in moderate sunlight during the gloomy winter days.
The most impressive thing is that even at its highest cooking temperature of 700°F this gadget is safe to touch. This is possible because of the vacuum between the inner and outer glass layers.
The package weighs less than 4 pounds and it is easy to assemble and dissemble when needed.
