Beating Motion Sickness
It's hard to have fun while you're nauseated. That's a truism that has endured from Admiral Horatio Nelson's days as commander of the British fleet in the Napoleanic Wars to these days of travel into space. Whether you want to be an astronaut, compete in a round-the-world yacht race, or pilot a Grand Prix racecar, susceptibility to motion sickness can be a limiting factor. Each year millions will experience the debilitating effects of carsickness, seasickness and airsickness, and while the phenomenon might help the paper bag industry, it sure isn't good for the rest of us.
A couple of important questions about motion sickness are: who gets it and what causes it? One of the world's leading experts in motion sickness, Dr. John Golding, sen ...
Hybrid Electric Vehicles
Four year ago when General Motors put its reputation on the line by introducing the GM EV1 electric vehicle it seemed as if vehicles powered by batteries would be the answer to the long-term problem of polluted air. There is more than a little debate over how much of our air pollution is actually caused by moving sources (read cars, trucks and buses), but there is no doubt that a significant percentage arises from these sources, even though the gasoline-powered cars of today put out just a tiny amount of pollutants compared with their predecessors of the 1960s, so the introduction of the EV1 as a car for the general public was a significant step. But, as it turns out, it might have been a misstep.
America's First Hybrid Electric
On September 23, 1999 American Honda Motor Company unveiled its Insight, the first gasoline-electric hybrid vehicle available in America. The little two-seater coupe was immediately lauded for its eye-popping fuel mileage numbers - 70 miles per gallon on the Environmental Protection Agency (EPA) tests. In fact, those startling fuel efficiency figures all but over-shadowed the fact that the Insight represented a breakthrough in ultra-low emissions in a car that could operate well with our current fuel delivery and highway infrastructure. Of course, the current infrastructure proved to be the bane of highly visible "pure" electric vehicles like the General Motors EV1. That vehicle's limited range and the nation's lack of recharging stations m ...
Can Electric Vehicles Compete?
A recent headline announced the demise of the once much-touted General Motors EV-1. A great deal was expected from the "pure" electric car whose power was stored in on-board batteries that had to be recharged using an outside source of current. Introduced with fanfare and accompanied by a clever advertising campaign, the EV-1 was predicted to usher in a new era of zero-emissions vehicles. Instead, it is leaving the road with its tail between its legs, as GM has tacitly admitted its failure.
