In Middle or High school you might remember those boring talks about magnets. If you have two magnets that have the same poles toward each other, negative and negative or Positive and positive, the repel. What if there were same pole magnets mounted on a cars suspension instead of the springs? If the
magnets were powerful enough to handle it it might save on gas and it would make one heck of a smooth ride.
The Bose Suspension System

The Bose suspension required significant advancements in four key disciplines: linear electromagnetic motors, power amplifiers, control algorithms, and computation speed. [ed, Jan 07 2008]

Please google "Bose Suspension" |

This has been done here even before I suggested it.
Look at "Magneto-electric suspension" or any of the other ideas here. |

I don't see what the big difference would be in between this and regular springs. Now an active system for shock absorption would be neat (I think that's what Bose is working on)... basically you have a "normal" suspension and a series of linear motors (read electro-magnets) take care of variations.

I think the hard part would be programming it for grade variations and operational accelerations. |

How could this possibly save on gas? |

If you're using permanent magnets, you're going to need an awful big pair of them to generate the kind of lift you're going to need, and even then you won't have the height needed to counter typical road variations unless you move them pretty far in along the locating arms, and then you'll need even bigger/more powerful magnets to fight the added leverage. That adds a lot of mass. It takes gas to move mass. |
|
| |
The other option is you're going to use electromagnets to repel the chassis from the suspension, which is good: you'll probably be able to get more height that way. It isn't massless of course, but probably won't weigh more than the original springs. But now you're putting a drag on the alternator. It takes gas to lift mass. |

Image of this car, instantaneously flipping upside down on its lower suspension components then going nowhere until you prise the magnets apart and balance it back on your magic magnetic carpet again. |
