...push for fuel conservation. Scientists are increasingly ) convinced that the burning of fossil fuels is contributing to the greenhouse effect, a potentially dangerous warming of the globe caused by carbon dioxide and other exhaust gases. Unless the growth of fuel consumption is slowed dramatically or nonfossil energy sources, including solar and nuclear, are expanded rapidly, the world could face climatic changes leading to widespread flooding and famine...
...news has upset antinuclear activists and raised questions about American + plans for nukes in space. The U.S. has not launched a nuclear satellite since 1977, relying instead mostly on solar-powered models. But Pentagon officials are planning the eventual use of atomic spacecraft in the Strategic Defense Initiative, the Government's proposed space-based defense system. To prevent that idea from going any further, U.S. Representative George Brown, a California Democrat, introduced a bill in Congress last week that would bar American nuclear-power sources from space -- on the unlikely condition that the Soviets do so first. The only exceptions...
Many of these problems did not start with the Reagan Administration. And though the national conceit puts the presidency at the center of our political solar system, no President can shine so brightly that every shadow disappears. Reagan's failure was to deny frequently that the shadows existed. While incumbency rounded out some of his early one-dimensional ideas, Reagan clung tenaciously to his phobias concerning Government intervention and federal taxes. Even Bush has had to acknowledge that Washington must act more vigorously in some areas, but Reagan to the end fought that reality. In one of his several farewell...
...sunlight, were briefly in vogue during the energy crises of the 1970s, and while public attention and Government funding have waned, research into the technology has continued. "The capital costs have come down from about $50 a peak watt to $5," said Speth. If they drop to $1, solar power will become competitive. That could happen without significant Government research support -- but it will happen sooner with...
Sometime early in the next century, solar enthusiasts hope to see vast tracts of photovoltaic collectors providing cheap electricity that can be transmitted over long distances. Alternatively, the electricity could be used to produce hydrogen from water. That could open up all sorts of possibilities. Cars, for example, could be redesigned to run on hydrogen, and that would produce a dramatic reduction in CO2 emissions...
