Your 2 cents. - ADDRESSING the WORLD'S ENERGY NEEDS

If one calculates for the volume of the whole Earth, it would lose 1 degree Fahrenheit on the whole in 8,116,577,132,522,888 years if used at the rate of all the world's non-renewable energy consumption in the year 2005, as I figure it.

Admittedly it may not be the easiest to reach initially. Yet there are numerous areas on the earth are generating volcanic activity and the likes that are quite near the surface. As I heard it, South America has 600 active volcanoes. Alaska have a few also, among them being the Aleutian Islands; basically a chain of volcanoes off the ocean floor. Kilimanjaro is at the end of a fault line that is splitting off a part of the African continent. Krakatoa is on the rise again. I say, "Cool it! School it!" to all these hyperactive molecules, anyway...

If ones gets deep enough, it may be possible to get it anyplace on the planet. If could one use carbon composite materials for the drilling pipe, one might be able to go quite deep even with some of the most common drilling rigs. As the pipe will practically float in the fluids used to lubricate the drilling head. As for the concern of getting the heat off the surface of the earth; one should note that the deserts have shown that losing energy is not hard if the sky is clear. They are noted for frying one in the day and freezing one at night. In fact the word dessert is a derivative of the word desert. By insulating things in the day time, desert people were able to make a cold treat long ago without a refrigerator. As far a the sources being rather distant; one might note that New York City now has a super conducting power transmission line to Niagara Falls, from what I've heard.

With geothermal energy to spare, one can then use carbons sources, of what ever type, to make carbon composite building material. The military is a big fan of them now. Waste management process can be much more effectively done at a cheaper price. And other great enhancements to life style could happen, since the price of the energy required would be cheaper.
