In this interactive activity adapted from NOVA, learn about eight of the latest solar technologies: thermal trough, mirrored dish, power tower, thin film, concentrated sunlight, solar paint, evacuated-tube collectors, and sun-grown biofuel. In the face of global climate change, scientists and engineers are actively developing new ways to harness the free and renewable energy of the Sun as an alternative to fossil fuels. Look at photos, an illustration, and text to investigate how these technologies can provide environmentally friendly solutions.
