Sunny Grill: and fries, and cooks and bakes pancakes

Technology, the basis of which is the free energy of the sun, are increasingly part of our lives. In addition to the already familiar to all solar panels and solar collectors, enthusiasts around the world are working on the improvement of solar concentrators. We have already talked about the world's largest gelioelektrostantsii and about solar oven to bake bread. Today we introduce you to this development, as a portable solar grill.

Interesting history of this device, developed by an international team of scientists.

Several years ago, I visited one of the western provinces of China. During his visit, I talked to people, leading a nomadic life. Going into the tent, I saw that the shepherds still cook on primitive and unsafe stoves with an open flame. Such stove smoke, and to prepare a meal, women have to collect firewood.

Kathleen talked to people. They told her that would be happy to use more modern cooking techniques food, if not for the high price of bottled gas or electricity generated by gasoline generators.

Talk, as they say, sunk into the soul. Kathleen decided to create a furnace to work that does not require fuel. Thus it was created an international project called "Solar power". After several years of experiments, researchers from the US, China and Norway have created a solar concentrator portable grill.

Commercially manufactured device is somewhat similar to satellite dish, covered with a reflective mirror coating. The basis is a parabolic concentrator "plate" collected from five separate beams, curved according to a previously calculated arc.

The sun's rays, falling into a plate, reflected and converge at a single point. The exact center point of the placed field - the so-called hob, which can put a frying pan or saucepan.

For user convenience, cooking and safety in the back of the cutout made grill. Being in this place, you can cook a meal without worrying that obozhzhoshsya or damage to the eyes due to the bright sunlight.

Sunny grill was tested in different climatic zones and weather conditions. Of course, during cloudy weather or rain in the installation will not work, but the inhabitants of hot regions, with plenty of sunny days per year, have appreciated our solar grill.

The device weighs 18 kg, making it easy to transport and may be assembled and disassembled by one person for 10-15 minutes. The diameter of the plate - 1.3 meters. At the peak power to the grill "removed" to 1 kW of power.

Furthermore top versions, developed a simple model of the device where instead of rigid petals used reflective fabric coated with a thin layer of aluminum.

Developers emphasize device that does not require external fuel and energy sources for solar grill. The user does not have to chop wood, gather firewood, to buy coal. Solar grill is cheaper than solar panels or a wind turbine. No moving parts, electronics, etc. simplifies the design, which is especially important for people living in remote areas and countries of the "third world."

The only thing you need to do - is to clean the reflective surface of the fat. Feedback from users, after some practice cooking easier with the help of the sun, safer and more interesting than a conventional grill.

Additionally, since No flames, hot coals and smoke, there is no risk of fire, making this construction demand from truckers and lovers of picnics.

In addition to cost savings, the solar grill is an environmentally friendly device that can be used to boil water and cook food, even in winter, the main thing that was the sun.
