Abstract
INDIA, South America, and other countries interested in the employment of sun power for mechanical purposes, have watched with great attention the result of recent experiments in France, conducted by M. Tellier, whose plan of actuating motive engines by the direct application of solar heat has been supposed to be more advantageous than the plan adopted by the writer of increasing the intensity of the solar rays by a series of reflecting mirrors. The published statements that “the heat-absorbing surface” of the French apparatus presents an area of 215 square feet to the action of the sun's rays, and that “the work done has been only 43,360 foot pounds per hour,” furnish data proving that Tellier's invention possesses no practical value.
