Dr. Erich Farber: Solar Expert

A brief look at the research of solar expert Dr. Erich Farber as Director of the Solar Energy & Energy Conversion Laboratory at the University of Florida-Gainsville in the early 1970s.

solar farber - solar equipment
Assorted solar energy equipment is displayed at the University of Florida's Department of Solar Energy Conversion Research and Development Laboratory, headed by Dr. E.A.. Farber.  
solar farber - solar refrigerator
A refrigerator—center of photo—is driven indirectly by the sun's energy as Ole Sol heats oil to a high temperature. The hot liquid is then circulated around the generator of the cooling unit's ammonia-absorption system.
solar farber - closed cycle engine
This solar-driven 1/2-horsepower, closed-cycle, hot-air engine can also—without modification—be run on wood, coal, or liquid fuels
solar farber - thermo-phase engine
This sun-powered thermo-phase, shift reciprocating engine consists essentially of a column of water inside a tube which has a bellows at its top. As the liquid is vaporized and condensed by solar heat, its movement operates the bellows which-in turn-can spin a flywheel at several hundred rpm.
solar farber - parabollic mirror
Various mirrors of good quality are used in this parabolic concentrator. The device develops the high temperatures needed to run sophisticated, sun-powered engines.
solar farber - open cycle engine
An open-cycle hot-air engine which works by taking in atmospheric-pressure air, compressing it, heating the air with the sun's energy, and then letting it exhaust as it expands.
solar farber - electric car
This electric car, driven daily by a laboratory staff member to obtain operating data under highway conditions, uses both nickel cadmium and lead-acid batteries. The batteries can be charged by using either solar cells or a sun-driven generator to produce electricity.
solar farber - glass engine
This closed-cycle reciprocating engine was built of glass to show its basic design. Just seconds after an outside heat source (usually the sun, but in this case, a heat lamp) is applied to the generator, the liquid inside begins to pump steadily through the apparatus.
solar farber - umbrella cooker
Dr. Farber designed this portable solar cooker more than 10 years ago. It's merely an umbrella which has been coated with a reflective cloth, and which has a cooking rack mounted at the end of its handle. During unexpected downpours, you can use the ""cooker"" to keep you dry until the sun comes out again!
solar farber - parabollic reflector 2
Cylindrical parabolas designed to track the sun are very efficient collectors of solar energy. This one, which measures 6' x 8', has a glass-covered focal tube. It has been used to produce heated water vapor for a fractional-horsepower steam engine and to heat the oil which operates a solar refrigerator.
