Hello: 
 First of all thank you for your concern about solar cooker! 
 Do not know where your home, I can only give you about! 
 Kerosene or electricity prices, in order to save money, people began to think of another way to save money, solar cooker that came into being in this trend, the use of 2 - 4 square meters of reflective panels to the sun to a point, the point of maximum temperature can reach 1,000 degrees, the summer home of a pot of boiling water we use only ten minutes, the winter 35 minutes faster than the coal fire, slower than the gas, boil water for cooking pancakes and porridge drying clothes, everything, one year can save a ton of coal, if your home's yard near asbestos manufacturing, raw materials like look. At present, I can plant development 1.0 - 10.0 square meters a variety of models, folding, portable, automatic tracking solar cooker, solar cooker, and indoor-type solar cookers can save energy being developed. 
 The shortcomings of solar cookers: 
 1. Cloudy rain can not use 2. Interior of the house can not be used 3. Cities with less (can not be used inside buildings, barber or sell) 
 I hope you think carefully, and his market, mainly in rural areas. In case you Baipaoyitang waste tolls. 
 Open a solar cooker factory, in their own yard can be produced, start-up capital 500, and then you can scroll through the production, the risk is small. 
 I graduated from college, did not find a job, own business, the effect can be, away from home, fearing being taken, in my place Do not worry, you can not bring money, the first visit, satisfied, let the money home, you can also correspondence . I die, the sample you send them over.
