Straight from the sun, the latest breakthrough in clean fuels involves a solar-powered Ford Ranger pickup truck. The only exhaust emitted is water vapor. A joint project of Xerox Corp. and Clean Air Now, an environmental group, the experimental technology to be unveiled today in Los Angeles makes hydrogen fuel from sunlight concentrated in photovoltaic cells.

CORONADO, Calif. -- The U.S. Navy has decided to spend as much as $600,000 for landscaping and architectural modifications to obscure the fact that one its building complexes looks like a swastika from the air. The four L-shaped buildings, constructed in the late 1960s, are part of the amphibious base at Coronado and serve as barracks for Seabees. From the ground and from inside nearby buildings, the controversial shape cannot be seen.

In a move that took experts by surprise, Houston-based Enron Corp., a giant energy developer, has proposed building the world's largest photovoltaic power plant at the Energy Department's Nevada Test Site, near Las Vegas. Equally unexpected, in an industry now producing electricity at a pricey 25 cents a kilowatt-hour, Enron says it will make power at 5.5 cents--which would make power converted directly from sunlight competitive with fossil fuel plants.

The fall equinox last week signaled the official end of long, sunny days in the Valley. For some kids, especially those interested in science, less sun can mean more incentive to try to "capture" it, or at least its power. Kits to build high-tech solar collectors for school experiments or to fuel toy airplanes and water mills are now available at selected toy stores in the Valley. One Canoga Park firm, Sun-Mate Corp., the largest U.S.

Re "State's Energy Problem Has Roots Nationwide," Commentary, Jan. 3: I question the argument made by Bertram Wolfe and Chauncey Starr that solar power is impractical on a large scale because of the immense land use. It may be impractical for major corporations to use as a vehicle for profits, but it is not impractical to use in individual situations, and no more land will be used. If every roof in Southern California was covered with photovoltaic cells, there would not be an electrical energy problem.

Designer-builder John Stebbins' innovative "holistic house," in which every aspect of modern energy-conservation techniques and equipment are used in every portion of the structure, is open for touring every weekend in the Meadowview section of Rancho California.

Imagine a solar power plant on the roof of your house that is as efficient at converting energy from the sun into electricity as crab grass is at taking over your lawn. Those two processes are not as far apart as they might seem. Both use photosynthesis, upon which all life on this planet depends. Plants use photosynthesis to produce the fuel for their growth, and in the process remove carbon dioxide from the atmosphere and make the oxygen we breathe.

One benefit of fall--and our return to standard time--is that we now rise to find sunshine, instead of gloomy half-light. On the other hand, darkness descends awfully early in the evening. But instead of stewing in the dark, this could be an opportunity to raise our consciousness about the importance of a simple thing like sunlight.

Just decades ago, with oil, coal and hydroelectric power lighting the world and driving its industries, alternate sources were dismissed by critics as utopian "wood chips and windmills." Since then, alternatives, most lumped under the category of renewable energy, have benefited from an infusion of technology, the faith of investors and the increasing expense of conventional fuels.

The bright orange flames of kerosene wick lamps used in millions of impoverished households around the world are significant sources of global warming and pollutants linked to respiratory diseases, according to a new study. Lab and field work led by researchers at UC Berkeley and the University of Illinois at Urbana-Champaign showed that 7% to 9% of the kerosene consumed by the crude burners is converted to black carbon -- a 20-fold increase over previous estimates, the study published online this month in the journal Environmental Science & Technology said.
