McLaren's ultrasonic force field to replace windshield wipers: "Windshield wipers are life-savers, but can also drive one to distraction with their incessant streaking and chattering. Well, the tyranny of the wipers may soon be over. McLaren Automotive’s chief designer Frank Stephenson has told The Sunday Times that the performance motoring company is investigating the use of "ultrasonic force fields" to replace windshield wipers in automobiles. While Stephenson referred to a military source for McLaren's tech, there appears to be very little public information on how such force fields might clean a windshield during a storm, so I'm taking a look at the patent history to see how this might be accomplished."
