Contributions

He traveled extensively in the United States, the Far East, Malaya, Asia, and Europe to conduct investigative surveys. His research works and technical papers were published not only in the Philippines but in Europe as well. His books, L'etude du compass, Magnitique e induction, and his article, "L'etude seismologique de 1'0 de secondaire," were published in Paris, France in 1930. His locally published research works were "Development of Commercial Aviation in the Philippines," "Prediction of Airplane Performance at a Glance," "Commercial Aviation in the Philippines", "The Technical Aspect of the Arais & Calvo Manila-Madrid Flight," "Photo elastic Stress Determination," "The Propeller-Cutting Machine," and "Industrial Alcohol as Aircraft Fuel." He has a total of 30 devices and equipment patented to his name. Namely: earth induction compass, used by pilots for direction; the vapor chamber, used to visualize radioactive elements; the wooden microscope; solar energy devices for areas not reached by power lines; a functional robot; the photo-phone, which allowed audiovisual phone conversations; a functional alcohol-fueled plane; wooden aircraft propellers; and a corresponding propeller cutting machine. Dr. Zara became internationally known for his scientific inventions. His magnetic and induction compass was awarded the "Brevet d' invention" by the Ministre de Industrie of the Kingdom of Belgium. His invention of the semi-automatic propeller making machine and the first aircraft engine using industrial alcohol as fuel drew admiration from aviation circles throughout the world. The other products of his inventive genius included the "solar-sorber," which makes use of solar power for ordinary household needs, and the two-way "television-telephone," a device that permits a caller to see the picture of the party being called, and vice-versa.
