    • It is rather common nowadays that museums, especially those of the "science center" type, have showcases where visitors can perform experiments. In the Futures' Museum in Borlänge we have made an exhibit where interested persons can construct parabolas. In this note we describe this showcase. Analogous exhibits can be made for constructing ellipses and hyperbolas.

  • Journal article (peer-reviewed)abstract
    • Two different concentrating mirrors have been constructed that resemble parabolic dish reflectors. Both mirrors are made of slightly curved strips of flat, bendable material. The strips of the most simplified mirror have only large-radius circles and straight lines as boundaries. The necessary equations for making the mirrors are given. Also a simple way to make a stiff, lightweight frame and support for the mirror strips has been developed. Models of the mirrors have been built and successfully used for cooking and baking.

  • Reports (other academic/artistic)abstract
    • Two different concentrating mirrors have been constructed that resemble parabolic dish reflectors. Both mirrors are made of slightly curved strips of flat, bendable material. The strips of the most simplified mirror have only large-radius circles and straight lines as boundaries. The necessary equations for making the mirrors have been derived. Also a simple way to make a stiff, lightweight frame and support for the mirror strips has been developed. Models of the mirrors have been built and successfully used for cooking and baking. This report is an extended version of a paper to be published in Solar Energy that contains complete derivations of all mirror design equations.
