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 - 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 - 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 - 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.
DR. E.A. FARBER
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 - 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 - 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!
DR. E.A. FARBER
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 - 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.
