'Technology in action'

FAIR HAVEN, VT. - The vehicle made a very uncar-like thrumming sound as Justin Severance turned it over early Thursday afternoon. "That noise is the power brakes," said the 16-year-old sophomore from Fair Haven Union High School. Severance was behind the wheel of a hybrid electric car he and 21 other students at the school had built from scratch during the past four years. As he began to drive, the thrumming gave way to equally uncar-like buzzes and chirps. When he came to a stop, the car fell silent.
