Think about this. That waste heat wasn't free. It's unused energy. That means you've had to put much more potential into the gasoline engine to get what you need. With electric, less energy is required. Of course, the heat is nice when it's cold. Still, from an energy perspective, the gasoline engine is rather wasteful. That's a shift of the subject, which was range under worst-case conditions. Since you bring-up efficiency, I wonder what the total efficiency of the electric system is. Waste in the generation process. Waste in the distribution process. Waste in the charging and discharging of the batteries. Waste in the electric motor. -- "I love how chrisv was trying to insinuate that being able to rotate an image was a useless feature." - "Slimer", lying shamelessly |

Well, I got 200 amp, and I'm out in the boonies. Your a business. Makes a difference. I have 100 amp in this house and my last two. I can get more but would pay dearly for it. bill |

Exactly, My father in law Had a 1968 Chrysler Stn wagon, 224,000 miles best car he ever owned. My son had a 1988 Toyota ForeRunner 241,000 miles, 1 PS pump, warranty Great. He then had a 2003 Chevy Silverado 195,000 KM,nary a problem . He also had a Dodge Magic wagon, Piece of crap So now you can say there are millions of good ones and yes a few lemons. Rene |

It's not bad. Depending on where you are, you can figure the overall loss between the plant and your doorstep to be between 10% and 15%. (Mind you if you live in some place like Hawaii where the grid is rather small, it can be better than that). Efficiency of the power plant itself isn't so good, it's on the order of a 35% loss on the average. Can be better in some places, worse in others but that's about typical for coal or gas fired systems. (Now, if you live in someplace like Hawaii it's worse than that because you have to take into account the waste in getting the coal out to you which is pretty substantial in such places.) Efficiency of the motors is very close to 100%. I don't know what the efficiency of the battery is and that could be a big issue although that's a thing that is still improving. Figure typical gasoline engines have maybe 10% to 30% efficiency. Again that is a ballpark number... you can guarantee that an Olds 442 in stop and go traffic isn't going to get anything like that, and you might do better than that on the highway with a small modern engine. But I'm thinking if you did the math more precisely it would tend to be a tossup. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Just for grins I thought I would take a shot at starting it and running the temp up before covering it. Started right up and ran really well. So much for the a bunch of myths like: a) British cars are crap b) gasoline cars (especially with carburetors) don't work when it gets cold Gotta love it. bill |
