Electric car? There must be a plot!

The best idea I ever saw for powering a car was the electric motor-wheel developed by Hydro-Québec some 8 years ago. But something screwed up during the development and although it worked perfectly fine (only two wheels could pushed a big Chrysler Intrepid from 0-60mph in 8 sec, imagine four), they apparently dropped the project.

Many people are still revolted that Hydro-Québec decided to cancel the motor-wheel, since it was the only electric-based motorization that was powerful enough to bring decent performances for average-sized cars.

I'm pretty sure some big oil company put pressure on Hydro-Québec in a way or another, (wouldn't be surprised if it was Esso, bunch of bastards), to put the motor-wheel in the grave.

The principle of the motor-wheel was, at large, to make the wheel spinning by injecting an electrical current in coils placed inside the wheel. They were able to apply 3 times more pressure on the wheel with their prototype than a Ferrari of the mid nineties.

Hydro-Québec still owns the patent for a few years, but nothing good will come out of it. It would have been so great. I have no words to describe the idiocy of the manager who decided to cancel the project.

I'm guessing it was pressure from some oil company to drop the project since it would have greatly decreased demand for fossil fuels. The idiot that dropped it should be made to suck on an exhaust pipe until he croaks.

I too have often wondered why we don't just do away with the mechanical transmission in road vehicles and power cars via electric motors in the wheels powered by either a battery, an engine powered generator, or solar cells (or some combination of all three). The battery will provide stored power upon demand for quick bursts of acceleration, the gas engine power for steady cruising (and to recharge the battery), and solar panels will supplement the output of the gas engine.

I'd guess that you could run the car at moderate cruising speeds entirely on solar power on bright days, and at highway speeds you would still get perhaps a third of your power via the sun. Other times the engine will supply the power, but it can be a much smaller engine, and since it will run at it's most efficient RPM rather than constantly speeding up/slowing down, it will be smaller as well as run more efficiently.

100 mpg is not unrealistic from such a setup, and perhaps 150 to 200 mpg once ultra-efficient solar cells are available. Small wonder the oil companies likely killed it as it eventually would bring the demand for gas to 10 to 15% of what it is now.

Electric motors are the best way to power vehicles. Some commuter trains I used to take had a 250 HP electric motor on each axle(1000 HP per car). These were able to accelerate a train of cars of 61 tons (plus passenger load) each up to 80 mph from a dead stop in under a minute(0 to 60 took about 35 seconds).

Now imagine what 100 HP of electric motors on a 1 ton car can do. My best estimate is 0 to 60 mph in about 6 seconds. Electric motors can also be overloaded at twice or more of their rated capacity for a few minutes so you can easily cut that figure in half if you can hit the battery for the extra juice. I don't think you can do better than about 3 seconds due to the limits of tire-road adhesion. For the same reasons it is difficult to get a train up to 60 mph in much less than about 25 seconds, even if power is unlimited (which it never is).

These observations are 3 ½ years old….

Where is our electric car? TG

ya that is common sense for sure. like thoroughly emptying the shampoo or dish soap in the bottle you dont want to waste that. also squeeze out every last bit of tooth paste in the tube. our society is very wasteful and the companies want to keep us that way but we know better eh? Mac

TOYOTA CITY, Japan -- Toyota Motor showed off the production site of its gasoline-electric hybrid cars to journalists for the first time Thursday with a powerful message: The fuel-saving autos don't have to be expensive to make.

Not long ago, many leading automakers, including the world's biggest, General Motors, questioned the benefit of developing hybrid cars, arguing that the gas-sipping autos are merely an interim solution before zero-emission fuel-cell vehicles take over.

They accused -- possibly accurately -- Toyota and Honda Motor, the only other mass producer of gas-electric hybrid cars, of selling them at a loss given the labor-intensive assembly required.

There may have been some truth to that argument before, but no longer, says Toyota, which launched its second-generation Prius hybrid sedan in Japan last month.

"We used to build the previous Prius on an exclusive assembly line at the Takaoka plant, and later at Motomachi," said Kenji Takahara, head of administration at neighboring Tsutsumi plant, which now builds the Prius.

"Now, it shares a line with four other mass-production sedans," he said.

That's a big and necessary step for Japan's top automaker as it aims to offer the hybrid option on most of its models in the not-too-distant future. Toyota is hoping to sell 300,000 of the fuel-efficient vehicles a year starting mid-decade. [Wired News]
When the hybrid goes purebred, we will finally have a true marvel of transportation.

Doing away with the gas motor and all of its many moving parts, the oil pump, gas pump, fuel injection, fuel ignition, radiator and rubber hoses, exhaust system, muffler, catlytic converter, air oil and gas filters, will also mean fewer repairs.

Zero emission Electric autos are here now and zero emission fuel cell cars coming soon will make hybrids passe.

Some hybrid owners are converting their cars to run predominately on battery power. = TG

It should be noted that the motor wheel was but one of the breakthroughs HQ made, and that unfortunately not only were the projects mothballed on the basis of undemocratic undisclosed behind closed doors political pressure but (corrupt) Oil and Gas executives were placed at the head of HydroQuebec (instead of HQ executives)to make extra sure no such research would have a real chance of making it(give researchers the run around, once progress is made mothball the project and switch engineers to another project, etc).
