"Geothermal Energy: Tapping the Earth's Heat"@en . . "This Science Screen Report looks at a clean and renewable energy source that is steadily gaining scientific acceptance: hot dry rocks, otherwise known as enhanced geothermal systems. The program shows how masses of heated granite approximately 3 miles underground can be accessed with advanced drilling and computer imaging techniques, and how water forced through fissures in the granite can generate steam to produce electricity. A solid foundation for studying emerging alternatives to fossil fuels. A viewable/printable instructor's guide is available online. Produced in association with the Accreditation Board for Engineering and Technology and the Junior Engineering Technical Society. (15 minutes)."@en . . . . "Videorecording"@en . . .
