"Science screen report". Title from cover. Title from cover.

This DVD looks at a clean and renewable energy source that is steadily gaining scientific acceptance: hot dry rocks, otherwise known as enhanced geothermal system. The DVD shows how masses of heated granite approximately 3 miles underground can be accessed with advanced drilling and compute imaging techniques, and how water forced through fissues in the granite can generate steam to produce electricity. An excellent resource for students interested in emerging alternatives to fossil fuels.
