. A fine overview of an alternative energy source. This short, entertaining video illustrates the ways in which geothermal energy has revived the steam engine of yore. The program details different approaches, from tapping naturally-occurring steam, to using the heat of the Earth to boil liquids in a sealed man-made environment, while also highlighting the positive environmental aspects of geothermal projects."
