I used a small solar thermal device that I made out of tin foil and cardboard to boil noodles. I have posted a how to video on building the device below. Please check it out and have fun builing your own.
To make noddles I cut open a large Arizona Ice tea pop can and painted the bottom with high heat flat black spray paint. It was cloudy and late afternoon so I only used 200ml of water and a small amount of spaghetti.
My Girlfriend and I might sell our motorcycle and travel the world with bicycles with solar thermal powered trailers. We could use the solar thermal device to cook all our food. I am hoping to make some long bread in this device soon.
