A solar cooker, or photo voltaic oven, is really a device which uses the power of sunlight to warmth food or drink to prepare it or sterilize it. High-tech versions, for instance electric ovens operated by solar panels, are possible, and also have some advantages for example having the ability to operate in diffuse light. The huge most of the solar cookers presently being used are relatively cheap, low-tech products. Simply because they use no fuel and price absolutely nothing to operate, many nonprofit organizations are marketing their use worldwide in lowering fuel costs for low-earnings people; reduce polluting of the environment and slow deforestation and desertification, triggered by utilization of fire wood to cook. Solar Cooker is a kind of outside cooking and it is frequently utilized in situations where minimal fuel consumption is essential, or the possibility of accidental fires is high..
Simple Solar Cooker
You will find various quite simple solar cookers, which have been designed using the following fundamental concepts:
- Focusing sunlight: A reflective mirror of polished glass, metal or metallised film can be used to target light and warmth in the sun right into a small kitchen area, making the power concentrated and growing its heating energy.
- Transforming light to warmth: A black or low reflectivity surface on the food container or within a photo voltaic oven will improve the potency of turning light into warmth. Light absorption converts the sun’s visible light into warmth, substantially enhancing the potency of the oven.
- Trapping warmth: Reducing convection by separating the environment with the oven in the air outdoors the oven. A plastic bag or tightly sealed glass cover will trap the air inside. This causes it to be easy to achieve similar temps on windy and cold days as on hot days.
- Green house effect: Glass sends visible sensational looking blocks infrared thermal radiation from getting away. This amplifies the warmth trapping effect.
Different Types of Solar Cooker
The different types of solar cookers have somewhat different techniques to be used, but many stick to the same fundamental concepts.
Meals are prepared as it might be have an oven or stovetop. Because food cooks faster when it’s in more compact pieces, solar cookers usually cut the meals into more compact pieces compared to what they might otherwise.
The container of meals are placed within the solar cooker, possibly elevated on the brick, rocks, metal trivet, or any other warmth sink, and also the solar cooker is positioned in sunlight. When the photo voltaic oven is entirely in sunlight, then your shadow from the solar cooker won’t overlap using the shadow associated with a nearby object.
Conclusion of Solar Cooker
The Solar Cooker or photo voltaic oven is switched for the sun and left until your meals are cooked. Unlike cooking on the stove or higher a fireplace, which might require a lot more than an hour or so of constant supervision, food inside a solar cooker is usually not stirred or surrender, both since it is unnecessary and since opening the photo voltaic oven enables the trapped warmth to flee and therefore slows the cooking process.
