Geyser Eruption Mechanism as a Way of Extracting and Utilizing Underground Heat

This article proposes a method for extracting hot water from a well drilled until the point where temperature exceeds the boiling point of water at a given depth. Core of this method lies on the physical mechanism of the eruption of a natural geyser. It bases on the cold water erupting from the well after entering inside from the surface of the earth due to the gas liquid imbalance (hereafter GLI). This column of water rises up due to the mutual movement between contacting liquid and gas by the pressure of the gas applied on it. The paper researches the physical conditions under which spontaneous outflow of hot water from the well to the surface begins. Described method of extraction of underground heat allows to eliminate the cost of energy required for the operation of circulating pumps of traditional geothermal power plants, since the heated water will be thrown out to the outside, obeying the GLI mechanism. Thus, this method can be considered as an environmentally friendly and significantly reduces the cost of extracting heated water from the well.
