[Darnit, UB, ya beat me to the punch. My answer was about the same as yours:] |

Sure. And the cars will lose kinetic energy and therefore need to be a bit more powerful to maintain the same speeds as before. And all things being equal, they'll have to burn a bit more gasoline. |

Sadly, you'd almost certainly come out ahead designing a really efficient generator to burn an equivalent amount of gasoline instead--and that's baked. |

Whoops, here's how you could make it work: install the coils only on downgrades steep enough that cars would normally have to use their brakes. The coils + magnets will slow the car some and you'll generate some power, but the cars won't have to burn extra gasoline! (We've already seen some proposals for extracting the energy from car brakes, though.) |

You guys left him speechless. |

Now this wasn't shitty per se, just a tad impractical. And there was an odd bit where he posted a response below my anno indicating he didn't get the gist of our objections...by the time I finished a clarification he had erased his response, so I think our good friend FreeNRG got the picture but perhaps did not realize he could delete the entire post and merely erased his verbiage instead. |

Don' ee be s' hard 'im, eh? It's not like he's a troll or toilet-mouth. |

I think he's just temporarily out trying to get the sewer lids pried off the magnets under his car. |
