Solar Cooker

Solar cookers are used to cook food and pasteurize water for safe drinking.They use a free, renewable energy source and do not pollute the environment.

Introduction

* Concentrating sunlight* Converting light to heat*Trapping heat

Process Flow

Firstly, solar energy which is an abundant, clean and safe source of energy, came from sunlight where it is transferred heat through radiation. After that, the solar energy radiates onto a surface of solar panel, where it is either absorbed and turns into heat (dark colored surface).The solar panels need to be physically large to collect sufficient power from the sun.Then, an inverter turns the DC voltage from the solar panels into an AC voltage, so that the transformer can step the voltage up to match the requirement of the solar cooker.Finally, a solar cooker will functions a device which uses the energy of direct sun rays to heat, cook or pasteurize food or drink.

Operation

* Prevent deforestation* Prevent pollution* Easy to run
