The end of the windshield wiper as we know it

Fox News: McLaren suggests high-frequency sound waves to clean windshields​

The reign of the windshield wiper could be coming to an end.

The McLaren automobile company is working on a vibrating windscreen designed to clear away water and debris, The Sunday Times reports.

McLaren chief designer Frank Stephenson says the design is based on fighter plane technology that uses high frequency sound waves to repel rain, bugs and other potential obstructions.

... while it sounds very advanced, one expert tells the Times that it could require only a small transducer to send 30 kHz sound waves across the glass and cost as little as $15 per car.

Must be a slow news day. There's this, a story on unworkable incinerators the Army bought, and a repeat of the story about veterans' benefits being on the line in the news budget. Plus, FNC has spent all morning covering the possibility of explosives on the Harvard campus.

Finals week, everyone in a hurry to go home for Christmas, it's cold, lots of snow on the ground, no one wants to get out of bed.

"Hey, I know, let's call in a bomb threat!"

How long these people been in education, anyway?

If one REALLY needs to hear some loud noise, one should have been blessed to be assigned to the propulsion branch of the USAF's F-102 "Delta Dagger" fighter-interceptor jet during the 1960's.

When that aircraft's single jet engine's afterburner was in the max position, one could stand nose-to-nose to another person and scream at the top of one's lungs and still not be heard by the other person!

Yep, them was the good ole days!! :thumbsup:

In my last post, I also failed to mention the fact that many of the super-sonic jet fighter aircraft [i.e., those capable of flying above Mach 1] employ the use of highly compressed air from their jet engines [usually from the 16th stage of compression] to simply blow off any foreign objects away from their front windshields.

This would be comparable to an automobile's windshield's high speed defroster--except for the fact that the warm air from its motor would be directed on to the outside of its windshield rather than to the inside of it.
