Solar grill: cooks, cooks, bakes and pancakes Bashny.Net

Technologies, which are based on free energy of the sun, are increasingly part of our lives. In addition to the usual solar panels and solar collectors, enthusiasts around the world are working on the improvement of solar concentrators. Today we will introduce you with this design as portable solar grill.



The history of the creation of this device, developed by an international team of scientists.

A few years ago I happened to be in one of the Western provinces of China. During my visit I talked with people, leading a nomadic life. Going into the tent, I saw that the shepherds still cook on primitive and unsafe stoves with open flame. Such ovens smoke, and to cook, women had to collect firewood. Kathleen talked with the people. They told her that with the benefit of more modern methods of cooking, if not for the high price of bottled gas or electricity produced by gasoline generators.

The talk is sunk into the soul. Kathleen decided to create an oven, which would require no fuel. Thus was created an international project called "solar source". After several years of experiments, researchers from the US, China and Norway has created a portable solar concentrator grill.



Commercially available device somewhat resembles a satellite dish covered with reflective mirror coating. The basis of the concentrator is a parabolic dish, assembled from five separate petals, bent at a pre-set arc.



The sun's rays falling on the plate, are reflected and converge at one point. Right in the center of this point a hosted platform — the so-called hob, which can put the pan or pot.



Due to the effect of a magnifying glass the sole of the pan onto the peak power of the grill is heated to 300°C.


For ease of cooking and safety of the user at the rear of the grill made the cut. Being in this place, you can cook without fear that will burn or damage the eyes because of the bright sunlight.



Sunny grill has been tested in different climatic zones and weather conditions. Of course, in cloudy weather or in rain, the installation will not work, but the inhabitants of hot regions with lots of Sunny days during the year, appreciated our Sunny grill.



The device weighs 18 kg, making it easy to transport and can be assembled and dismantled by one person in 10-15 minutes. Valve diameter is 1.3 meters. At the peak of the power from the grill "removed" up to 1 kW of power.Besides the top version, a more simple model, where the petals used instead of a hard reflective fabric coated with a thin layer of aluminium.

The developers emphasize that solar grill does not require fuel and foreign energy sources. The user don't need to chop wood, collect firewood, buy charcoal. Solar grill is cheaper than solar panels or a wind turbine. The lack of moving parts, electronics, etc. simplifies the design, which is especially important for residents of remote areas and third world countries.

The only thing to do is to clean the reflecting surface of fat. Based on feedback, after a workout to cook with the sun easier, safer, and more interesting than on a conventional grill.

In addition, because there is no flame, hot coals and smoke, there is no likelihood of fire, which makes this design popular among the vacationers and picnickers.

In addition to saving funds, solar grill is an environmentally friendly device, which you can use to boil water and cook food even in winter, the main thing that was the sun. published
