“Due to the fuel crisis in Nepal now we don’t get gas for cooking. I just wanted to ask you if you have some idea regarding building a solar cooker. I did some search in google but I could not come up with a concrete idea. And yeah I have a methane gas chamber in my house. Do you have some idea to improve that as well because its not enough to cook 2 meals. Thank you.” Prateek

One big advantage of solar ovens is you can leave the food cook all day without worry of burning or scorching. Things like rice and beans are perfect. Start in the morning and everything will be cooked by dinner time. Some foods cook faster.
