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.

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.

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.

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.

“The energy crisis is really nothing new,” says Dr. E.A. Farber, solar expert and Director of the Solar Energy & Energy Conversion Laboratory at the University of Florida in Gainesville. “We were already running short of fossil fuels, our so-called ‘conventional’ sources of power, 40 years ago. It just hadn’t come to the public’s attention at that time.”

Maybe not, but the world’s supply of energy and its relationship to the development of nations most certainly had already come to the attention of a few farsighted individuals back there in the early 1930’s, and Austrian-born Erich Farber was one of them.

Four decades ago, while still a high school student, Farber observed that the countries and civilizations which controlled the most energy–and used it–were the nations and cultures that also advanced most rapidly. Young Erich further noted that the power providing this advantage came mainly from the fossil fuels–gas, coal, and oil–which obviously (to him, at least) would one day be exhausted.

“This led me directly to solar energy,” Dr. Farber says. “I thought of the planet’s human population as a family trying to live off its savings (fossil fuels) which were stored in a bank (underground) and which were being steadily depleted. This, of course, cannot go on indefinitely. Sooner or later that family has to begin living on its income, sooner or later we have to make do with the amount of renewable, incoming energy we receive. After mulling over the possibilities of wind, geothermal, tidal, and other sources of power–all very good when the conditions are right for their use–I realized that the sun alone offered the resource I was seeking. Solar energy is readily available, well distributed, inexhaustible for all practical purposes, and does not pollute the environment when converted and utilized.”

Farber developed his ideas as he received the major part of his education in Europe and during the time he studied at the Universities of Missouri and Iowa. He further honed his keen interest in solar power while teaching at the Universities of Missouri, Iowa, and Wisconsin. By the time he moved to Gainesville–20 years ago–to instruct at the University of Florida, Erich was quite possibly the planet’s most enthusiastic and knowledgeable authority on the subject. Little wonder that the University of Florida’s Solar Energy Lab is one of the largest and most advanced facilities of its kind in the world.
