Eco Solar Cooker is a cooking utensil invented by Earth Cardboard. Using silver-colored cardboard, it collects the sun’s heat and light. The cooker is convenient for outdoor cooking such as camping and barbecue and useful as a disaster kit.

Eco Solar Cooker:

- is handy because it is lightweight and small before being assembled.

- is disposed of easily.

- can make small donuts.

- can cook rice.

It is a very convenient item but water-sensitive because it is made of cardboard. Therefore, Earth Cardboard applied a varnish coating to Eco Solar Cooker to make it water repellent. Eco Solar Cooker can be used even in case of light rain or splashing by a child playing with a water gun.
