Geothermal energy is the all-natural heat of the earth. Geologically, the earth can be divided, from the surface to the interior, into four layers – the crust (five to 40 km in thickness, temperature from 15 oC to 500 oC), the mantle (2885 km in thickness, temperature from 700 to three,000 oC), the outer core (2270 km in thickness, temperature at about 5000 oC) and the inner core (radius of 1216 km, temperature at about 7000 oC). Heat is continually generated by the decay of radioactive elements from the molten interior and flows outward to the surface of the earth.
I highly recommend watching the videos I posted on both wave-particle duality and quantification from Quantum Created Simple at The animations are a excellent way to visualize the abstract ideas. In the first video, what they contact a quantum object is a representation of wave-particle duality, an object that has the properties of both.
Geothermal heat comes from the magma in the earth’s core, and that itself is heated by the radioactive decay of uranium, thorium, and potassium present in the core. Geothermal power is present everywhere beneath the Earth’s surface, while the highest temperature, and thus the most desirable, sources are concentrated in regions of active or geologically young volcanoes.
We have limited amounts of a fossil fuels in our disposal. Projections say that there are coal reserves for about one hundred years from now, even though the oil and organic gas could final us for about 50 years in the future. Of course, these predictions are relative, consist of only identified deposits, and their accuracy substantially depends on the technology and industry development, and the rate of power demands raise.
Hot dry rock, on the other hand, can be found about three to 5 miles deep down the earth’s surface. In specific locations, they can be located at lesser depths. To extract heat from these rocks, cold water is injected down a properly which filters via the cracks in the rocks situated in the hot region. Heated water is sooner or later drawn off from the recovery effectively. This then flashes into steam upon reaching the surface.
