This is a how to video so that you can build a solar thermal device to boil water using the sun.
All you need is some cardboard, white glue, tin foil and a small piece of wood.
In this video I built a unit that is 2 ft by 8 inches to boil water in a glade aerosol can. I boiled 500ml to make mr noodle soup. This unit could also be used to distill water or run small steam engines. Please take a look at my other videos as I build larger solar units and find different uses for them using homemade machines.
Please build this unit and give me some feedback. This was built in La Paz Mexico and I will be traveling the world to build and show people how to build similar units.
