It is spring in the Northern Hemisphere, and most of the trees and other plants are being sexy. The air is full of pollen, therefore. It gets onto everything. And any automobile that gets washed in the morning will have another dusting of pollen on it before the day ends.
There is a toss-up between
driver safety (need to see through windshield!) and the global need for fresh water (don't waste it, please!) We need a better way remove pollen from cars, therefore.
I will suggest a Van de Graaff generator. If you put your hand on one **before** it charges up, then you can safely experience 400,000 volts or so. Each hair on your head (if you have any) will receive an electric charge and will be electrostatically repelled by all its neighbors, and your head will look something like a dandelion about to loose its seeds into the wind.
So, what about attaching your car to a Van de Graaff generator? The solid rubber tires will offer excellent electrical insulation, so that a nice large electrostatic charge can be applied to the vehicle. This charge will be easily conducted throughout the metal body of the car, and some of it will certainly be conducted to the coating of pollen. The pollen will then be electrostatically repelled.
The fun way to do this, of course, is to charge up the Van de Graaff generator **before** running a wire to it from the body of the car.
ZAP!!!
All the pollen immediately goes something like **spuunnng** away from the car! Well, maybe all of it. I'm not so sure about the windows, unless they are specially coated to conduct electricity. Which makes this Idea Half-Baked, of course.
(Remember, after turning off the VdG generator, you need to run your connecting wire to the ground, to remove the static charge on your car. Also, remember to do that before you yourself touch the car!)

[+] But why external ? It'd make a good accessory. |
|
|
Some kind of proximity detector which picks up large objects
could probably automate the earthing. Wouldn't you need to
isolate the engine and tank electrically from the rest of the
vehicle to prevent fire? What about the electrics in the vehicle?
Sorry if these are stupid questions, it's just that electricity is a bit
of a dark art to me. |
|
|
It would certainly deter squeegee merchants. |
|
|
I can see nothing at all wrong with this idea.....except you forgot to mention using the VDG generator in the manner of a Tesla coil and amuse yourself (and others) with renditions of the Ghostbusters theme while stuck in traffic. |

I like this. But, how non-conductive are rubber
tyres? I thought they contained carbon black, and
were therefore slightly conductive? (On the other
hand, it's possible to get a static shock when
stepping out of a car, so maybe they're not very
conductive.) |

Has anyone suggested moustache-style electrostatic
pollen filters for hayfever sufferers? |
|

1) Strangely, no. But I'm guessing some of that territory might be covered by the electric cheese nose filter TM, pat pending. See link, if you really must. |
|
|
2) I'm thinking a layer of lead to shield out electro-magnetic interference on the electrics...but then of course it'd be a lead zappolen. |
|
|
3) Hmm, just found out you actually can focus x-rays, or was I just the last person to find this out for himself? Admittedly you need a gold mirror and angle of incidence of a 3.5 degrees-ish. |

[nineteenthly], I'm pretty sure the ordinary electrics in the car can handle a sudden zap. The electronics, however, will probably be fried. However, the slow way of charging up the car (connect to VdG before turning it on) probably won't hurt the electronics (you will also need a slow discharge method). |
|
|
Don't forget that any discharges will also damage the paintwork... |
|
|
[mitxela], that is not necessarily so. If the conductor-wire is attached to the frame under the car, then the other end of that wire is what you bring to the globe on top of the VdG generator, for a nice static-electric build-up. Then you take that end of the wire and touch a grounding-post, to discharge the car. For a slow discharge, you want an appropriate resistor included in the discharge system (probably attached to the grounding-post). |
|
|
As far as getting yourself zapped, simply rig the chirpy keyring thing to turn it on/off. |
|
|
sorry, I was referring to arc discharges like discussed above. The slow discharges should be fine. |
