About This Lesson
Concentrated sunlight is a versatile and high-quality form of energy with several potential applications besides producing heat and electricity. Today, scientists are developing systems that use concentrated sunlight to detoxify hazardous wastes, to drive chemical reactions, and to treat materials for increased hardness and resistance to corrosion. These activities by the U.S. Department of Energy are: Can sunlight break down different kinds of plastics? Can hydrogen peroxide work with sunlight to break down dyes? Can sunlight be used to clean up water? Make a solar dehydrator.
