A very special thing about the idea is the simplicity.
The device is able to convert impressive 85 of the incoming solar energy into heat.
Augustin mouchot demonstrated a solar collector with a cooling engine making ice cream at the 1878 universal exhibition in paris the first installation of solar thermal energy equipment occurred in the sahara approximately in 1910 by frank shuman when a steam engine was run on steam produced by sunlight.
Solar energy is the technology used to harness the sun s energy and make it useable.
A solar cooker is a device which uses the energy of direct sunlight to heat cook or pasteurize drink and other food materials.
The reasons for this are obvious.
