Translations:Solar coffee roaster (using a Scheffler concentrator)/5/en

Let's go! The 3D modeling of the roaster, including the solar concentrator, is available online on OnShape. The current version --so far (contribution welcomed ;) )-- corresponds to the geometry suited for Peru (13° latitude). In comparison to the version proposed in this tutorial, there are some slight differences: inclination and height of the focal point, especially. But the drum size and many other elements remain unchanged. If you do not have a Scheffler concentrator, you will find the building tutorial online. (1000€ of materials and 15 days work). The Scheffler concentrator manual is available here online.
