I wanted to explain compound parabolic reflectors to people but there was no suitable software to explain it so I made up this little set up instead. It might be a useful tool for many people.

Compound parabolic dishes differ from parabolic dishes in that they have an acceptance angle (a margin for error if you like) so they do not have to be exactly pointed at the sun or moved every few minutes. This is a very useful property!
This video shows how i made a mold for making parabolic dishes suitable for up to 3 hours of solar cooking before moving the dish. The mold can be used with whatever sheet material is available to make the dishes.

Briquette Production at the Grady Grossman School, Cambodia. In January 2008 Sanu Kaji Shrestha of FoST in Nepal trained the local villagers of Chrauk Tiek, Cambodia how to produce biomass briquettes from waste materials such as saw dust, rice husk, rice straw, leaves, coconut husks and scrap paper. Over 40 villagers were trained and a production facility was established. Now 19 workers (17 women) produce 4 tons of "Smart Choice Fuel" per month. A more permanent facility is being built. Sales of this alternative cooking fuel is brisk—selling all the villagers can produce. Net profits from sales go to support education at the Grady Grossman School. This method of sustainable development is the work of Sustainable Schools International. To learn more visit: http://www.SustainableSchoolsInternat...
