Solar Cooker

New way for cooking food is through this new explored technology. By using 'fuel' from the sunlight and by promoting using the solar cooker, it help to slow of deforestation and desertification by less use of coal or methane as fuel for cooking. Quite interesting when no cost incurred and in Malaysia, we have enough source over the year just by 'harvesting' the sunlight out of your home. New cost-free method that absolutely need to implement in our home!

Types

The most common types of solar cookers are as below:

1. Box cookers

This box cook at moderate to high temperatures and often accommodate multiple pots. This is the most popular type of solar cooker.

2. Parabolic cookers

Curved concentrator cookers, or "parabolics", cook fast at high temperatures, but require frequent adjustment and supervision for safe cooking. They are very useful for large-scale institutional cooking.

3. Panel cookers

Panel cookers incorporate elements of box and curved concentrator cookers. They are simple and relatively inexpensive to buy or produce. The most popular brand for this panel cooker is "CooKit".

Principles

Basicly, the solar cooker is using this basic principle; sunlight is converted into heat energy that is retained for cooking. It work best when in dark, shallow, thin metal with dark surface, tight-fitting lids to hold in heat and moisture.
