Utilizing the Earth’s Central Heat.

One of the schemes for future engineers to work at, says an article in Current Literature, will be the sinking of a shaft 12,000 or 15,000 feet into the earth for the purpose of utilizing the ceutral heat of the globe. It is said that such a depth is by no means impossible, with the improved machinery and advanced methods of the coming engineer. Water, at a 'temperature of 200 degrees centigrade, which can, it is said, be obtained from these deep borings,would not only heat houses and public buildings, but would furnish power that could be utilized for many purposes. Hot water already at hand is necessarily much cheaper than that which must be taken when cold and brought up to the required temperature. Once the shaft is sunk, all cost in the item of hot water ceasee3. The pipes, if good, will last indefinitely, and as nature’s stokers never allow the fire to go out, there would come in the train of this arrangement many advantages. When, by sinking a shaft in the earth we can secure a perpetual heating apparatus which we can regulate by the turning of a key, one trial of life will fade into nothingness.
