This has been simply pretty open-handed with people like you to present openly just what some people would have marketed as an ebook to help with making some cash for themselves, primarily seeing that you could possibly have done it if you ever decided. These tactics additionally acted to provide a easy way to recognize that most people have the identical fervor the same as my own to find out a little more when considering this problem. I know there are several more enjoyable moments ahead for many who discover your website.

This was really given much attention by this people since the government seems to forget people in the hinterland or budget for this saw spent somewhere else. The town's people was very thankful about this since they can already watch television after a days work in the farm or they have lamps on little store where they used together around after dinner. This is very helpful since electric bills are goingup every year. This is a big help for end consumers.

Over-engineering of a simple problem. Parabolic shapes need to be highly accurate in order to make them efficient to use. Hand drawing parabolas will create more of a bowl shape than a parabola. The best way to create a parabola is to use a simple piece of CAD software and to have a good understanding of how parabolas work ref parabolic equation. Hope this helps. Hi Johny

The higher the reflectivity the better the performance of your solar cooker. Mylar and chrome vinyl have a reflectivity of approx ~ 98%, so these are the preferred materials to use as they are the most cost effective. Emergency blankets and food wrapping foil would work fine. Perhaps best used on box type cookers as you can stretch these materials out and get rid of any creases/folds. From all the various methods and materials I have tried when building solar cookers, I have to say that the parabolic design with chrome vinyl is the most cost effective method which produces the best results. Let me know if I can be of any more help. Happy solar cooking. Hi ChibiHoshi
