This video examines reenactments of heliograph communications. The heliograph was one of the first solar experiments in territorial Arizona. In the late 1880s, the U.S. Cavalry employed the heliograph during hostilities with native Americans. Solar developments in Arizona during the 20th century are explored. From the Eneas Engine to the Day and Night solar water heater to solar cookers and passive solar architecture. Pioneers Arthur Brown, John Yellot, Sherry Cole and Barbara Kerr are recognized for their contributions to solar development in Arizona and elsewhere.
