The need for developing technologies, which would result in geothermal free energy, is imminent. This is a largely untapped area of tremendous substitute energy potential, as it simply taps the free energy being naturally produced by the Earth herself. Enormous amounts of free energy lie under the upper crust of the earth, on which we lie, and all that is required is to tap the source and take control over it.
The temperature at the center of the earth is 60 times greater than the boiling point of water and the heat emanating from it create forces which can be felt only a few miles under the surface of the earth. This enormous heat is a store of massive free energy and result in super hot fluids called magma, which we can see whenever a volcano erupts. These fluids also filter to the surface as steam and come forth from vents.
We can produce our own vents, and we can produce out own containment chambers for the magma and convert all of this free energy into electricity to light and heat our homes. In the creation of a geo-thermal power plant, a well would be dug where there is a good source of magma or super hot fluid, then pipes would be fitted down into the source, and the fluids forced to the surface to produce the needed steam. The steam would be used to produce electrical energy, using a turbine.
There are criticisms of geothermic energy tapping which prevents it being implemented on the large scale which it should be. Critics say that exploration to find a resourceful location is too expensive and takes up too much time. Additionally, set up cost of a geothermic plant is again cost-prohibitive and there is not guarantee that the venture would yield profits later. It might so happen that a geothermic site becomes unable of creating enough steam which makes it unworkable and uncertain.
Unfortunately we also hear from environmentalists who worry that bringing up magma can bring up potentially damaging materials along with it. However the advantages of geo-thermal energy can easily beat these criticisms, if only we examined the matter in greater depth. The fact is this is the free energy of the Earth herself means it does not develop any pollutants. geo-thermal free energy is an cost-efficient energy source – easy to produce after site identification and the set up of the plant to develop it.
A geo-thermal plant is also not as huge as say a dam or an atomic free energy unit, making it a lesser risk to the environs. Using this alternate source of free energy would naturally reduce our dependency on coal and oil. Perhaps most significantly of all, we are never, ever going to run out of geothermic free energy, and it is not a commodity that would continually become more expensive in terms of real dollars as time goes on, since it is ubiquitous. The use of geothermal energy would be exceedingly affordable and the cost of building a power plant can be recovered expeditiously.
