Pertandingan Dapur Cekap Tenaga(Solar Cooker Cempetition)
Power Point Presentation
Abstract
- We invented this ASS Cooker is to overcome the problems that occur in countries that have hot climate such as India and Bangladesh.
- Most of the citizens can not buy cooking appliances because of their stricken-poverty life.Major of them use wood and charcoal as their cooking fuel.This can cause global warming which is one of the biggest problem in the world.
- By using ASS Cooker, we can reduce the usage of non-environmental fuel and can save non renewable fuel that is depleting day by day
Introduction
- Solar cooking is the most convenient way to preserve non-renewable source that finish because of the human needs.
- It also save money and time.To make it we do not need to pay a lot of money because the materials of solar cooker is affordable.it also save our time because the material can easily be found in stationary or shop around our livinghood.
- Solar cooking can easily be made by the correct use of materials and the correct principles of heat conductors which can produce a perfect solar cooker.
- Solar cooking also can increase our healthiness because there is no fire to cause burn. It can also preserve our healthy by drinking the water that cook first because it can prevent the presence of bacteria.
Objective
- To make sure the renewable energy specifically solar energy.
- To reduce the usage of non-renewable energy such as petroleum.
- To save time because food cook unattended while we can do other activities.
- To increase air quality since it decrease the burning traditional fuels.
- To save money as the solar cooker saves precious money.
- PRINCIPLES OF INSULATION
- -The materials used is polyfoam.
- -It is poor conductor of heat.
- -The polyfoam also act as a good insulator of heat.
- -It will retains the heat inside the cooker
- PRINCIPLES OF GREEN HOUSE EFFECT
- -The greenhouse effect traps the heat inside the cooker.
- -The temperature will increase.
- -So, it will cook faster.
- -The principles of heat that occur is convection
- Black surface
- -it absorbs heat better than the other colours.
- -as a good radiator of heat.
- White surface
- -it reflects heat better than black dull surface.
- Solar cookers save money and time.
- Solar cookers are safe,healthy and convenient.
- Solar cookers are adaptable.
- Solar cookers help the air quality.
- In short.we know that invention of solar cooking gives lot of benefits to us specially those who lives in bangladesh,ethiopia and etc.Solar cooking also encourages people to take care of environment such as by reducing air pollution.Besides that.solar cooking also increase air quality.For example,it reduce the usage of wood and fuel that may cause smoke which can irritate of the lung.So that,the invention of solar cooking must be proceed for our next generation.
