Short's technical writings were well known and he was a prolific inventor. He did many things related to electrical and streetcars. He designed and produced the first
electric motor that operated a streetcar without gears. The motor had its
armature direct-connected to the streetcar's
axle for the driving force thereby eliminating energy-wasting gears. Short pioneered the use of a
conduit system of a concealed electrical third rail and cabling thereby eliminating the necessity of
overhead wire,
trolley poles and a dangerous exposed electrified third rail of street cars and
trolley railways. While at University of Denver he conducted important experiments which established that
multiple unit powered cars were a better way to operate trains and trolleys. He later resigned his professorship at the University of Denver and gave his entire attention to street railway work. He built a number of street railway lines in the western cities of the United States using both the underground conduit and overhead electrical trolley systems. Short interested the electrician
Charles Francis Brush into investing into his electrical inventions and electrical machinery improvements. They formed a new company called Brush Electric Company in 1883. In 1885 he pursued an interest in electrical apparatus construction, and development of
electric railway equipment. == Society membership ==
