Before CNG, electricity or hydrogen can be considered a serious alternative to gasoline, the driving public must be won over. That job may seem tough, says Wall Street energy analyst Charles Earle. But take heart. Back when cars were powered by coal-fired steam boilers, he points out, people "once thought it wasn't possible for cars to run on gasoline either...
...popular minivan. GM is experimenting with automobiles that run on methanol, a form of alcohol that comes from such sources as coal and wood. United Parcel Service recently tested delivery trucks that burn propane rather than gasoline. Mercedes-Benz has developed a prototype car that runs on hydrogen...
Less than an hour after engineers began pumping 385,000 gal. of highly explosive liquid hydrogen into the fuel tank of the space shuttle Columbia, the countdown was halted and the flight scrubbed -- for the third time in just over three months. "We do not consider that the vehicle is safe to fly," declared shuttle director Robert Crippen, who earlier this summer grounded the entire fleet when leaks turned up in the shuttle Atlantis as well. NASA has not been able to get a shuttle off the ground since April, when it launched the now crippled Hubble telescope. Though shuttle...
...results have been both disappointing and intriguing: the experiments have detected far fewer neutrinos than solar models predicted. Scientists were especially baffled by a recent report from a Soviet-American research team that set up a detector to monitor neutrinos emitted by the fusion of hydrogen atoms, the sun's main reaction. After four months of operation near the Soviet town of Baksan, the experiment has yet to turn up a single solar neutrino...
...alternative energy source, geothermal generation is a proven technology. It supplies about 5% of California's electricity and provides power in two other states and about 20 foreign countries as well. Advocates admit that tapping the earth's heat in this fashion will also bring up noxious hydrogen sulfide and sulfur-dioxide gases, but they argue that the Kilauea volcano, just a few miles away, spews out far more of the very same gases...
