On a day in which stocks were up stoutly, San Diego-based Maxwell Laboratories dropped 12 cents to $12.22. One reason may be excitement about a new Texas company that claims to have a device permitting a motorist to plug in a car for 5 minutes and drive 500 miles without gasoline. By contrast, some plug-in hybrids are plugged in overnight and promise only 50 miles. A prestigious investment banking firm is behind this. Maxwell, a leading maker of ultracapacitors, is wary of the new firm. The device won't work with regular wall outlets, and capacitors could crack while going down the road, says Maxwell.
