Van de Graaff Systems have been developed for space heating and electrical power generation using solar power. And in fact, several thousand U.S. homes-primain Florida and the rily Southwest-a- re heated with energy from the sun. Electrical power generation by solar energy has played a key role in the space program, with solar batteries substituting for the much heavier conventional storage units. And research is continuing into developing prototype units for large-scal- e solar power generators. Governmental agencies and priing vate several oil companies-a- re currently in or engaged sponsoring solar power research, in recognition of the role solar power may play in 21st Century energy supplies. With the exception of experimental units being developed or tested for a few public and commercial buildings, solar space and water heating has been limited to residences.

All of these methods, however, require conventional heating units for periods when solar power is not available (for example, at night or during extended periods of cloudiness). Passive space heating: An example of passive space heating is designing and locating a building to take maximum advantage of its exposure to the sun. Heat is absorbed through windows or by absorbent materials during daylight hours, and retained by curtains or other shields at other times. Passive heating adds little to new home construction costs, but can lead to overheating of the interior during the day. Active space heating: In active space heating, a collector (usually sheet steel, copper or aluminum coated with an absorbent black surface and d mounted in a shallow box) system traps the heat of the sun, which is' moved to the heating system by a liquid or gaseous medium and usually requires electrically driven fans or pumps. At present, collector systems are expensive and not cost effecglass-covere- tive. Optical heating: Much of the advanced technology in solar research is being devoted to developing mechanisms to optically concentrate the suns rays. Parabolic mirrors are used to focus the rays on a central collecting unit, which produces heat. This heat can be used for space heating purposes or for generating power to turn electric turbines. Optical units, too, are expensive, and require mechanical means to cause the mirrors to follow the course of the sun. Photovoltaic means capable of producing voltage when exposed to radiant energy, especially light. This type of cell offers the only presently available direct solar electricity. However, a substantial reduction in costs is required before photovoltaic systems can become econom- ically competitive with con- ventional energy sources for power generation or conversion to space heating. The nation needs to fully develop potential energy sources, such as solar power, which can contribute to meeting demand when conventional energy sources are no longer available. It is also' important to note, however, that solar power, as is the case with most of the sources, is expected to non-conven-tio- supplement, not replace, con- ventional energy. We will still have to continue to develop expeditiously our fossil fuels. continued from page 5b two weeks compared to a previous record of zero such sales. The new law, which became effective April 1, requires public places to provide separate quarters for smokers Restaurants barber shops and other regularly inspected places will be the most vulnerable to enforcement of the law. Dr. Harry L. Gibbons, Salt Lake Countys health director, said the penalty for breaking the law would be a fme, the amount of which is still to be determined by the county attorney. I believe the majority of citizens are considerate and will follow the law, Gibbons said. Offices are also required to comply with the new regulations, but, since they are not routinely inspected by health officials, the law will be more difficult to enforce there. We will respond to complaints, Gibbons said, describing how he expects to enforce the law. and non-smoke- rs. Budget Derails Track Decision Railroad tracks on 2nd West may continue to derail traffic for several more months. Due to multi-levgovernment red tape, a project favored by decisionmakers is being delayed. The railroad has agreed we may take out the tracks, says office engineer Vince Houtz, of the Salt Lake City Engineers office, but we have to find the money to repair the road once the tracks are removed. Were working with the State Department of Transportation for a joint program, says a Public Service Commission spokesman, but no date has yet been set for a hearing. The matter is still pending. Because both the Public Service Commission and the State Department of Transportation must approve railroad-related activity, the city el engineering department is awaiting the nod from both State offices.

We expect to have the budget ready by April 29, Houtz said, adding that by then the office should have a better idea when the track removal will take place.
