"Interview - Tesla Opinion on Power from Sun, Earth or Air," N. Y. Telegram, Feb. 27, 1928. (Commenting on the Hendershot "fuelless motor", Tesla says no natural source of power, except lightning, could be exploited for the operation of machinery.) (n)
"How Experts View Fuelles Motor," N. Y. World, Feb. 27, 1928. (Discussion of "fuelles motor" of Lester J. Hendershot, which consists of three coils and a circular magnet. Tesla said power derived from source of this type could only be measured in "mouse power". Refers to Century, June, 1900, for his analysis of the subject.) (n)

(Tesla has filed patent application for essential parts of a device that is a manless aircraft without wings or engine that will travel 300 miles per second. Will be sent by electricity to any place on the globe, for destructive purposes. Doubtful that invention of Charles E. Harris to provide an electric wall of fire around the country would be practical.) (n)
