Ten Solar Cookers that Work At Night
Solar cookers are great and all, but they need the sun to function. This means you can't use them to cook the evening meal after the sun has gone down, or cook breakfast before the sun as come up...and that seriously limits the use of solar cookers in the places where they can do the most good.
So Climate Healers issued a design challenge: Create a solar cooker that meets the following difficult criteria:
Here are ten solar cookers that met the challenge. Some of them even retask local waste products, like rice husks, coconut shells, aluminum cans, and sand. One of the entries even uses photon-enhanced thermionic emission to generate power.
So Climate Healers issued a design challenge: Create a solar cooker that meets the following difficult criteria:
- the stove must deliver 1kw of heat at about 200C,
- it must be able to function for about 2 hours in BOTH early morning and late evening,
- it must function indoors, and
- users can sit while using it.
