solar cooker

Solar cooker is a solar power heating device that uses the inexhaustible power readily available from the sun. This abundant energy from the sun is utilized by this heating device typically for the purpose of cooking, heating &amp sterilizing etc. Solar cooking is a form of outdoor cooking which is now becoming promoted to lessen usage of other exhaustible fuel which could end in the coming future.

A solar cooker is a straightforward heating device produced of a wooden box painted black. In order to concentrate the sunlight there is a reflective mirror of polished glass and a metalized film is placed usually to concentrate the light and heat from sun into a modest section of cooking area generating it far more distinct so that more amount of heat can be utilized. Thereby the heating power of the device increases. The next step mainly focuses on conversion of the light energy of the sun into a usable form of heat.

The absorption of the light is mainly converted into heat by a black surface on a food container or the inside surface of this device. This improves efficiency of the device. The next step entails the trapping of the heat energy. It is quite essential to reduce the convention by isolating air inside the device to make it far more efficient and functional throughout cold days. Due to the greenhouse impact the infrared thermal radiation can be prevented from escaping 7 due to this the heat trapping effect can be conveniently amplified.

For the formation of this heating device different heat principles like heat gain, heat loss &amp heat storage ought to be completely understood. Heat acquire is normally available in three main types like the greenhouse impact, glass orientation and placement and with the reflectors that are placed for additional acquire.

Heat loss happens by any one of the following ways like conduction, radiation &amp convection. Heat storage mainly depends on the density and weight of supplies involved. With this we can judge the capacity of this heating device as well.

The solar cookers are mainly of three kinds the box cookers, the curved concentrator cookers and the panel cookers. The box cookers can cook from moderate to high temperatures and these are the most widely employed range used more than the world with a numerous thousand in India. The curved concentrator cookers also called as the parabolic cook rapidly at high temperatures but they require frequent adjustment for much better functioning and secure productivity. The panel cookers are in fact a mixture of both of the above devices that is the box cooker ant the parabolic. They are comparatively simple and affordable to buy and use. The basic principle of these devices is mainly to convert sunlight into heat power and use it for cooking purpose to save fuel and other non renewable types of power.

The biggest benefit of solar cookers is that they are eco friendly, affordable and price productive. 1 can very easily let go the dependence on gas or electrical energy for cooking or heating purposes. They can even be utilized for grilling, roasting &amp baking purposes as properly. 1 of the key disadvantage of this heating device is uses the energy from the sun so it might turn out to be hard in winter months or rainy days when sunlight is not enough.
