As everyone knows, at the core of the earth there is another sun shining.  From this molten core come rivers of molten rock occasionally exploding at the surface as volcanoes.  In addition, the surface of our planet is dotted with geysers and hot springs.  We can use these geothermal heat sources to produce energy.  Again, while we could use water as in Fultonís steam engine, today we have developed chemically engineered fluids that change phase from a liquid to a gas at much lower temperatures, and then condense back to a fluid more efficiently as well.  These reusable petrochemical fluids are also far less corrosive to the pipes and vessels use in the processes than would occur by using alkaline hot spring water.  Again, a far better use for our petroleum, then us to keep burning it.



The first geothermal power plants in the U.S. were built in 1962 at The Geysers dry steam field, in northern California. It is still the largest producing geothermal field in the world.
