Description: Clear, sequential explanations are offered concerning the why and how of using solar energy directly. Simple experiments are performed and explained step-by-step by children. Presents commercial applications, the need for proper design in buildings ad present limitations as hopes and challenges for the future., In order to use energy from the sun we must concetrate it, absorb it, trap it, or convert it. Simple experiments by children and commercial applications explain.

Complete Record: , Emphasizes the importance of developing solar energy and presents simple experiments to explain how solar energy can be transformed into heat, light, and power. Distinguishes between indirect use of solar energy with wood or fossil fuels and direct use of the sun's energy. Demonstrates how the sun's energy can be used by absorption, by concentration, by conversion to electricity, and by proper home design. Shows applications of principles in various communities., NOTE: Two (or more) records have been merged together to create this data.
