New Wizard of Power

By Charles Frederick Carter

Cheap power is the prime secret of commercial success. Steam held the field alone for years. Then came electricity and, more lately, water power on a vast scale. Now the great shadow on the power horizon is cast by producer gas. The largest gas engine at the World's Fair in 1893 was of thirty-five horse power. To-day a single plant in California contains four gas engines each of 5,400 horse power. There is one producer gas power plant in the United States with a capacity of 40,000 horse power. Producer gas can be made, as Mr. Carter says, “anywhere, at any time, in any quantity, and from anything combustible." This article is of vital importance to every business man and manufacturer.-EDITOR.
