Corrosion resistant alloys and non-metallic coating have been tested by exposure to Glenwood Springs geothermal water in a test loop constructed for the purpose adjacent to the Glenwood Springs geothermal well. Several alloys were tested. None of the materials showed any measurable degradation during the test. However, it is recommended that the results be applied with caution; several factors suggest that the data from these tests might be overly...

The heat that comes from inside Earth is called geothermal energy. This clean energy source is used to heat or cool buildings and to make electricity. Readers will learn about this renewable energy source, how we do not pollute when we use it, and the future plans for using this geothermal energy on a wider level. Color photos, a geothermal energy timeline, and a glossary round out this title.

Traces the development of geothermal energy and explores its impact on both society and the environment.

This book describes how heat beneath Earth's surface and plants and animals can be used as sources of power, how using this power affects the environment, and what the future significance of geothermal power and bio-energy may be.
