Smile Windshield wipers - Soon a thing of the past?

The Humble windshield wiper is soon to be phased out, become a thing of the past thanks to the new technology which aims to shake off the water on the windshield using ultrasonic vibrations. The technology is making its way in McLaren cars and is expected to be costing apprx 10 GBP making it an ideal mass market manufacture. Suprisingly this low cost technology is finding its way in a 1700000 GBP car.

The elimination of the wiper will also reduce the weight of the car not so much but still sufficient to make it fuel efficient. Add to that this will prevent the usual problems of wiper blades sticking to the glass in hot summers and cold winters.

Very interesting to read about this futuristic technology. So sometime in the future, no more wiper blades swishing away. I wonder how effective it would be in blinding rain with sheets of water descending on the windscreen - we get many such days (& nights) during the height of the monsoon.

It might work to dispel liquids and ice but how will it dispel bird poo and dust?

IIRC, there was a similar feature but one which used compressed air that was supposed to debut on the '12 Passat, wasn't it?

I think it'll work through that as well:

By in effect creating a force field, water, insects, mud and other debris will be repelled from the screen.
Also, stay tuned as tuners unlock these features on their wiperless cars!

The new system will use high-frequency sound waves similar to those used by dentists for removing plaque from teeth and by doctors for scanning unborn babies.

I guess it is more to do with the aerodynamics/drag co-efficient than the weight loss.

That report mentions the weight of the wiper motors - and their removal assists in improving FE. I never knew that the wiper motor was heavy enough to have an effect on FE.

experts suggest that it may make use of ultrasound, waves outside the human hearing range, to create tiny vibrations on the windscreen.

These would in effect shake off any object that landed on the screen.
I have the same doubt as @wilful. How effective will it be in sheeting rain?

Apart, why not use this technology to clean the whole car? Kind of touch-less wash? Begone pressure washers, shampoos and dusters. Less swirls too. Or is it already in use? Or bad for paint?

Including to what BHP'ian DRIV3R had mentioned aerodynamics will also be better and sound of the air passing over the wipes will also not be heard.

I would still prefer the wipers in heavy rains

how will you do wash/wipe on your windshield with this new technology? On a lot of days, I use the windscreen wash/wipe to clear the dirt sticking on the windshield. With this technology, the water would be blasted away from the windshield before it gets a chance to clean

Analogy I see here is vacuum cleaner trying to replace mops for cleaning the floor. It could replace the brooms but not the mops.

If not the front, this would be a great addition to the rear windshield. Unlike the front , the rear windshield gets a single wiper and the unwiped area is quite high.

Also with more curvy rear windshield shape, wipers will not work effectively. With Indian conditions, where you see high mud percentage during rains (as opposed to say US) - effectiveness of this technology will be a question. Haven't we all seen extremely dirty vehicles with the only clean spot being wiper arc on the windshields?
