Steve Baer (1938- ) is an American inventor and solar and residential designer. Baer has served on the board of directors of the U.S. Section of the International Solar Energy Society and also on that of the New Mexico Solar Energy Association.

Steve Baer was born in Los Angeles. In his teens, he read Lewis Mumford and decided technology needn’t necessarily degrade or complicate people’s lives. In the latter 1950s, Baer worked at various jobs and attended Amherst College and UCLA. In 1960 he joined the U.S. Army, being stationed in Germany for three years. He also was married in 1960. After discharge from the Army, he and his wife, Holly, settled in Zurich, Switzerland, where he worked as a welder and again attended the ETH, studying mathematics. Here he became interested in the possibilities of building innovative structures using polyhdra (polyhedrons) other than rectilinear ones.

Baer and his wife moved back to the United States, settling in Albuquerque, New Mexico, where Baer initially worked as a welder of trailer frames for the Fruehauf Trailer Services company. However, he soon went into business by forming a small company called Zomeworks with Barry Hickman and Ed Heinz. The partners experimented with constructing buildings of unusual geometries and often using heavy sheet metal as the main exterior material. Some of the earliest experiments were carried out in cooperation with members of the intentional communities Drop City and Manara Nueva.

During this time Baer had also become interested in utilizing solar energy for direct heating of buildings, initially by reading Direct Use of the Sun’s Energy by Farrington Daniels. He began to experiment with practical methods, always seeking to simplify his approach as the experiments proceeded. Steve Baer was a key organizer of an important grassroots Western-American conference, Alloy, focusing on these matters. Because the conference was spotlighted in the Whole Earth Catalog, Baer and Zomeworks became better known amongst solar enthusiasts in the U.S. Baer also was known as the author of Dome Cookbook and Zome Primer.

In the early years at Zomeworks, Baer was able to work fruitfully with other innovators and idea people, such as the solar designer Day Chahroudi, Dave Harrison, and Dick Henry. In 1975, Zomeworks published a useful, succinct illustrated book, Sunspots, written by Baer; focusing on solar-design principles, the book was notable for its cognizance and insights.

Baer’s approach has been to develop strategies and products that simplify rather than complicate - that add to, rather than detract from, the self-sufficiency of a building and its occupants. The “Track Rack” which Baer and Zomeworks staff developed is a metal-framed passive-solar dynamic mounting for photovoltaic (p.v.) modules. Via an arrangement of cylinders, pistons, and tubing the device uses the differential pressure and movement of entrapped liquid to enable gravity to turn the rack and follow the sun. Depending on heat and hydraulics - without motors, gears, or computerized controls - the rack enables the p.v. module to face the sun (‘sunflower-wise’) for maximum efficiency. To fit into the developing solar energy industry, Zomeworks has designed and builds several Track Racks to fit all common photovoltaic modules.

Another innovation, the Skylight Tracker, has a dual purpose: it shades a skylight for indirect daytime lighting while making electricity from PV panels built into the shading slats.

Besides designing, testing, and fabricating solar-energy equipment, Baer and his company have provided consulting services to architects. Baer's design work was included in the Contemporary Developments in Design Science exhibit, St. John the Divine cathedral, New York, in 1995.

While Zomeworks has been known mainly for exploring passive solar strategies and equipment, more recently some of the equipment the company has developed for solar-driven space cooling has used active-solar principles.
