Eug,
<< By the way, the rapid growth of the scooter is not going to solve any problems. It would also be interesting to see scooters during winter in Toronto or New York. The only way to address this congestion problem is to seriously increase the infrastructure of public transport. I'm sure as hell not going to take the bus if it means waiting 30 minutes at the bus stop in -15C weather. However, I would if it meant waiting <10 minutes, or taking the subway. It would definitely make me happier if I didn't have to pay CAD$20000+ for a reliable car, because the operating costs of a car are still much higher than taking the bus. Just think of how much computer equipment that would buy. >>
I find myself mostly in agreement with you -- except for this point. IF an almost total switchover to extremely efficient, non-polluting personal transportation were to take place in the cities, it would have a huge effect on almost every aspect of the lives of city dwellers. It would also have an effect on life in general on the planet because of factors like...
1. the improvement such a change would entail in atmospheric quality -- When everybody and his Aunt Agnes is no longer trundling about in two-ton steel cocoons propelled by fossil fuel engines, the air suddenly becomes easier to breathe.
2. the reduction of the costs to society in maintaining the special infrastructures for fuel source exploration, refinement, distribution -- You use less dinosaur remains, you don't have to pump as much of it out of the ground, refine it, and carry it to service stations.
3. the reduction of the costs to society of maintaining large, high-traffic-volume roadways -- Large trucks would no longer be necessary. Why? Super high efficiency personal vehicles could virtually eliminate the need for large volume heavy traffic corridors between places that were not industrial sites. And that would suddenly make the use of rail traffic for the support of industry a much more attractive alternative. And just at a time when exciting and efficient new technologies along these lines are becoming available.
Of course, there's that word "IF" up there at the beginning of all of that. But IF is what IT is all about -- unless this is all just hype. You're talking about conventional scooters, or something closely related when you say that they're incapable of changing city life. Actually, scooters have changed life in London for many people, and they've been reducing traffic congestion in many Southern European cities for decades. And anyone who's been to Amsterdam has seen what even the lowly bicycle used en masse can accomplish along the lines of efficient transportation of large numbers of people.
Did you take a good look at the patent papers? In its various permutations, this device is always a single-axle transport with one or two wheels. Can't keep it standing? If you read the papers and know the physics you'll see that a proper implementation of the proposed device would be unbelievably hard to upset, far more stable over broken ground (or ice) than a multi-wheeled vehicle. From the standpoint of dynamic balance, this sort of thing has it all over the motorcycle and the car -- IF it can be implemented correctly.
Consider, too, the fact that this widget need not conform to ordinary standards of scooter architecture. The drawings accompanying patent applications seldom resemble the finished product closely. What if a scooter could be produced in a form which is enclosed, yet portable -- or at least storable in a very compact form? When I first heard about IT, I suggested that it might be a scooter with a single large wheel which encompasses the passenger compartment. This would be possible, if difficult, to construct with current materials and mechanical technologies. (I think, however, that I was incorrect in this supposition because the device needs to be really small to enable it to fulfill the "hype". And I can't imagine how to make device of the type I envisioned small enough. No matter which way you look at it, one of the largest problems with a car is -- where the heck do you park it?)
Okay, so we're all inundated daily with talk about dishwashing detergents that are going to revolutionize our lives. That's a good reason, besides a little knowledge of physics, to be skeptical about this whole thing. But I think that, if you ignore the salient features of the "scooter" depicted in those papers and look, instead, at the principles that underly it the single-axle portion of the design, you might be able to think of a LOT of different and very effective ways the concept might be applied to personal transportation.
When we look at the way city traffic was managed at the turn of the previous century, we can't help but wonder just how many people got run down by horse-drawn carriages and wagons -- and how much "debris" must have existed on the roadways. (Imagine a nice, muggy summer's day following a heavy rain! As large animal dung goes, horse is one of the better ones to step in. Cow is bad. Pig and sheep is right out! But horse manure in the city streets was more than a stench in the air and a mess on your boots. It contributed significantly to disease, particularly tetanus and other such maladies, in cities of that time. Just as automobile, bus and truck exhaust contributes to death by respiratory ailment now.)
Nowadays, there are lots of streets that have a pronounced tendency to turn humans into road kill. Think how overpowering our awareness of cars is, day in an day out, both when we're riding in them and when we're trying to walk without being run over by them. What if personal transportation could be made fast and efficient, but requiring scarcely more space or supporting infrastructure than transport by shanks mare? What if that device' cost were roughly a tenth the cost of a cheap automobile, and it's operational and insurance costs even more disparate?
I have no idea if Kamen has accomplished something of this magnitude, but such a device could actually have astounding effects upon human life -- especially in cities. If auto and truck traffic, and their ravages upon human safety and health, were rare to non-existent in cities like New York, imagine how pleasant such cities could become as places to live. Just a little speculation.

Jim
