There have been a number of experiments with putting electric motors in each wheel, some dating to the very early days of the automobile. Don't recall exactly how they generated the electricity, though, and can't speak to why we aren't using the technology today. There must have been some drawbacks or we'd be seeing it used today. There are at least two excellent hybrid cars at present, and more coming -- which partly solves one of the major problem of electric cars mentioned here: where does the power come from? The problem with having the electric motor in the wheel is what is called unsprung weight: electric motors are heavy puppies, and anything that can be done to reduce the weight of the wheel helps handling and stability. Also, having the motor on the frame, with drive shafts, means you can use a lighter smaller motor -- and every pound counts. I would note that diesel electric engines, while the motors are mounted on the truck, have them partly sprung (suspended).

QUOTE: Originally posted by zardoz My point is one that I did not see mentioned--that driving slower will drastically increase your mpg. And before you go off about haw you're so busy and can't afford to slow down, consider: at highway speeds, on average, each mph you go increases your fuel consumption about one percent. So at 70mph, you will get 5% less mpg. At 55mph, you will get 20% better mileage. (and at 0 mph you will get infinite mpg) :-)
QUOTE: Originally posted by oltmannd QUOTE: Originally posted by zardoz A number of responses here indicate very good reasons to own a larger vehicle. But if the reason is to haul a 4x8 sheet once a year, or the rare occasion that a need to haul arises (moving, buying a refrigerator, etc), one could rent a pickup truck for about $25/day. IMHO, many people drive big due to feelings of inadequacy or impotence. The big, macho look is important to some people. And some like to feel intimidating to others on the road. Consider the popularity of that race car driver that died last year. He was known as the "Intimidator" and was very popular. I think that says something about some people's attitude. And certainly, Mr & Mrs soccerparent do not need such a massive landbruiser. Sure, what you say is true, but if people want one and can afford one, then why shouldn't they have one? Is that more frivelous than driving several hundred miles a month in pursuit of a hobby such as railfanning or any other frivelous thing we do with our discretionary income - even if it is making up for some inadequacy?

Nothing is more fairly distributed than common sense: no one thinks he needs more of it than he already has.

QUOTE: Originally posted by oltmannd Us westerners are way, way beyond "need" for anything. All we need are food and shelter, which can be had in the crudest forms for only a few dollars a day (ask a 3rd worlder). In terms of sucking up the worlds resources, driving a small car is only marginally worse than driving a large SUV. For a small car driver to call an SUV driver "socially irresponsible" really misses the point.

QUOTE: Originally posted by donclark Simply put, compared to the rest of the world, Americans are selfish.... There are mountainous regions in Asia and Europe and Latin America but the citizens in these locations are satisfied with the performance of a 4 cyclinder or even a 3 cyclinder car. As for hauling freight, the farmers of these locations are satisfied renting trucks when the need arises or contracting out the hauling, rather thån owning a family vehicle that consumes gas at less than 30 mph. Most Europeans park their boats at marinas. They use tents for camping, which fit easily into many of their small hatchbacks....such as the Golf or Lupo.....

Don't fear- people Will go muddin' in a hybrid (Californicaters first!) and 'yer battry' won't go dead either. Embrace the 'new' technology- it's here to stay. If you don't end up owning one your children and/or their children probably will!
