Show LIQUID GAS. It has been known for a great many years that a gas, if subjected to sufficient pressure and a sufficiently suf-ficiently low temperature, would become a liquid. The air we breathe has been changed to a liquid by this process, and the modern illuminating gas has also been resolved into a liquid. To make a practical prac-tical application of this principle has been the subject sub-ject of much thought and experimentation among scientists for a number of years, with the idea of producing a liquid gas as a commodity of commercial commer-cial value. The constantly diminishing supply of the earth's natural fuels and the constantly increasing increas-ing price at which these commodities are sold has served to intensify the interest in the proposition to manufacture a gas in liquid form for producing heat and light. The report of the United States consul general at Zurich, in Germany, recently transmitted to the state department at Washington, tells the story of the progress made in that country with the manufacture manu-facture of liquid gas as a commercial commodity. From this report it is learned that the first plant for the manufacture of liquid gas was established in 190-1- in Augsburg, a Bavarian city. Success has followed the enterprise, a great many installations for heating and lighting having been made. Some of the German railways also have adopted the liquid gas as a means of illuminating passenger coaches. Another plant was established in 1T07 near Zurich, with apparatus sufficient to make nearly five hundred hun-dred pounds of liquid gas a day from crude oil. The . product is described as a transportable liquid, which is simply evaporated as used. A tank of the liquid gas in the house will furnish fire for cooking and heating, as well as light. , Jt has been nearly a century since the theory of changing & gas into a liquid was advanced, first, probably, by Faraday. When the principle was established, es-tablished, there remained the practical utilization ot the principle for the use and benefit of humanity. That the application of the principle has been made adds another remarkable economic discovery to this, "the modern age of new inventions." |
