Most Shatterprufe (thats how they spell it on my car) windscreens have a laminated plastic section on the outside to stop it from shattering.
Firstly we need to make this plastic layer a bit thicker so that it can hold a static charge.
Along the bottom of the windscreen, we have a static
electricity generator, a belt driven rubbing device. The static would repel the raindrops for just long enough so that they are blown over the roof.
"Hmm look at those dark clouds overhead - activate the shields, maximum settings!"

Nice. I'd be interested to hear from some physics bods if this is feasible. Could double as a bug-zapper too. |

I like the idea of a Van Der Graff generator on the roof of my car powering this. |

Wimshurst machines attached to all the wheels |

It depends if the raindrops have a positive or negative charge. Statistically, you'd probably end up attracting 50% of them. Besides, the fact that the vehicle will be damp, and operating in a humid environment, will make it extremely difficult to maitian any significant charge on the windscreen; it will just track and flash over almost continuously. |

Normally, your windscreen would be an unlikely target for lightning. However... |

//windscreens have a laminated plastic section on the outside to stop it from shattering//
Actually that's not how shatterproof windshields are made, at least here in the US. They are actually two layers of glass with a piece of plastic sandwiched in the middle to act as the bond when the glass cracks. So you'd need a new coating on the outside of the glass if this is to work. |

Shatterprufe ? Are you driving a Chevrolay? |
|

Don't your windscreen wipers work? |

I'd sooner invest in fitting a car with an aerofoil which is ducted to the area in front of the windscreen, free of charge. |
