A solar oven operates on solar energy. By exposing the oven to sunlight and ensuring a maximal absorption it is possible to cook meat, fish, vegetables and steam rice. The time it takes depends on the amount of sunlight. The top of the oven is made from glass or clear plastic and the inside of the oven is black, as dark colours absorb the most warmth. Place the ingredients in the oven and leave the rest to the sun.

Solar cooking does require a degree of patience as the cooking time is longer than conventional methods. However you can use the oven literally anywhere as there is no gas or electricity required and, of course, the energy is free. 

This is the reason that solar ovens are used in poor countries, where gas and electricity is scarce .

Under the right conditions, you can boil a liter of water in 10 minutes 

You can hire the solar oven at the main building.
