Optimally, much more of the energy consumed in the U.S. would come from renewable resources. However, much of the necessary technology, such as efficient fuel cells, is still under development. The costs of a rapid conversion to solar or hydrogen production would likely cause an energy price shock that would seriously dampen the economy. But the present American system of electricity production is archaic. While 10 percent comes from renewable resources—mostly hydroelectric—and 20 percent is nuclear, 70 percent is from burning fossil fuels...
...impending shift is pretty radical. Unlike batteries, fuel cells don't store electricity. They generate it, via a chemical reaction between a hydrogen-containing fuel and oxygen. Fuel cells have been around for decades in exotic applications, powering satellites and spacecraft. They are being developed for commercial use in electric cars and to provide backup electricity for buildings (a truly "green" technology: their only emissions are water vapor and heat). Strapping a power plant to a mobile phone once seemed a silly idea?early prototypes for portable fuel cells were as ungainly as a pair of clogs?but miniaturization...
...earth's temperature but could also lead to "large, abrupt, and unwelcome" climate change. So it was a particularly good week for DaimlerChrysler to introduce a new fuel-efficient minivan called the Natrium. It runs on a common compound called sodium borohydride. A chemical reaction inside the engine produces hydrogen to power the car's fuel cell, leaving behind not carbon dioxide (the primary culprit in global warming) but borax, a standard ingredient in many household soaps...
...heartbeat, hundreds of stories full of fevered theorizing gushed forth in the press. Ginger was a hydrogen-powered hovercraft. Or a magnetic antigravity device. Or, closer to the mark, a souped-up scooter. Even the reprobates at South Park got into the act, spoofing Ginger in a recent episode--the details of which, sadly, are unprintable in a family magazine...
Speculation about what Ginger would be ran rampant on many websites and discussion boards. Many thought that Ginger might be a type of hovering scooter or run on a Sterling engine, a highly efficient engine that potentially could run on a fuel such as hydrogen...
