"A new series of whimsical public service announcements [3] from the Environmental Protection Agency are lampooning the notion that cars can be made more energy efficient while the ads encourage conservation at home," reports Danny Hakim. The ads depict a wacky home inventor trying to make his car more fuel-efficient by adding a sail and "a helium tank with a bulbous hose ... Viewers are then directed to a Web site that lists energy-efficient furnaces, computers and dishwashers - in fact, just about everything but cars."
