The scientists in this article may want to adapt their solar concentrator for a more prosaic use: cooking. In the early 1970s, I was involved in a project to build a self-sufficient dwelling that drew solely on the wind and sun for its power. We looked into using fiber optics to transmit solar energy to the cooking area, but the materials available at the time turned out to be too inefficient and costly. Maybe it’s time to take another look at the culinary applications of fiber optic materials.
