Michelin Tweel could dramatically change tyre technology
Detroit January 10, 2005 Today at the North American International Auto Show, Michelin showcased a potentially disruptive technology with significant ramifications for the future for mobility: an airless, integrated tyre and wheel combination dubbed the TWEEL (i.e. Tyre/WhEEL) . The Tweel promises performance levels beyond those possible with conventional pneumatic technology. The first commercial applications of the Tweel will be in lower-speed, lower-weight vehicles such as the iBOT mobility device and Segway's Concept Centaur

Designed by Segway-inventor Dean Kamen, the iBOT mobility device has the ability to climb stairs and navigate uneven terrain, offering mobility freedom impossible with traditional wheelchairs.

Additionally, Segway's Concept Centaur, a prototype that applies self-balancing technology to a four-wheel device, has also been equipped with Tweel to increase its performance potential.

Beyond these first real-world applications, Michelin has additional projects for Tweel on construction skidsteers and a variety of military vehicles. Historically Significant

"Major revolutions in mobility may come along only once in a hundred years," said Terry Gettys, president of Michelin Americas Research and Development Center in Greenville, S.C. "But a new century has dawned and Tweel has proven its potential to transform mobility. Tweel enables us to reach levels of performance that quite simply aren't possible with today's conventional pneumatic technology."

The most intriguing application may be Michelin's early prototype Tweel fitment for passenger cars. The mobility company released video of promising Tweel performance on an Audi A4.

"The Tweel automotive application, as demonstrated on the Audi, is definitely a concept, a stretch application with strong future potential," said Gettys.

"Our concentration is to enter the market with lower-speed, lower-weight Tweel applications. What we learn from our early successes will be applied to Tweel fitments for passenger cars and beyond." Benefits of the Tweel

The heart of Tweel innovation is its deceptively simple looking hub and spoke design that replaces the need for air pressure while delivering performance previously only available from pneumatic tires.

The flexible spokes are fused with a flexible wheel that deforms to absorb shock and rebound with ease. Without the air needed by conventional tires, Tweel still delivers pneumatic-like performance in weight-carrying capacity, ride comfort, and the ability to "envelope" road hazards.

Michelin has also found that it can tune Tweel performances independently of each other, which is a significant change from conventional tires. This means that vertical stiffness (which primarily affects ride comfort) and lateral stiffness (which affects handling and cornering) can both be optimised, pushing the performance envelope in these applications and enabling new performances not possible for current inflated tires.

The Tweel prototype, demonstrated on the Audi A4, is within five percent of the rolling resistance and mass levels of current pneumatic tires. That translates to within one percent of the fuel economy of the OE fitment.

Additionally, Michelin has increased the lateral stiffness by a factor of five, making the prototype unusually responsive in its handling. Future of Tweel Technology

For Michelin, Tweel is a long-term vision that represents the next step in a long path of industry-changing innovations. Fifty years ago, Michelin invented the radial tyre and there is no question that radial tyre technology will continue as the standard for a long time to come. Michelin continues to advance the performance of the radial tyre in areas such as rolling resistance, wear life and grip.

In the short-term, the lessons learned from Tweel research are being applied to improve those conventional tyre performances. In the future, Tweel may reinvent the way that vehicles move. Checking tyre pressure, fixing flats, highway blow-outs and balancing between traction and comfort could all fade into memory. The History of automotive tyre development

Thank you courtsey of tap-ten yahoo.
 
I had encountered a young girl, who was a floor and sales associate, at a housing supplies, large store.

She was about five foot five, had black hair, (short), which was pink streaked and wore a leather bracelet, which had studs placed on it.

She wore black jeans, and a t-shirt, that was also black.

She wore the logo of her building supplies store on her blue vest.About nineteen to twenty years of age, I guess?

The first time I went shopping there, this girl was telling on the check-out tellers, that she built cars, for her class project, in high school.

I wanted to give this idea I had on cars, to her at that time, wrote it down as a matter of fact, but opted not to give her what I had written down, as I did not want to seem to be chasing her.

Time had passed and I went to the same store once more.

This time to buy different items, not related to when I had first encountered this girl, from a distance.

This time I had struck up a conversation and told this young and attractive, but punk-type girl, my proposals on electric vehicles.

She was leaning aginst a tall stocking shelf and smiled when I told her the following.

I said>"You know, if they could some how figure out how to emboss NASA high quality solar cells, onto the outside of an auto body during the manufacturing process, and then feed this constant hot from four large banks of solar cells into both a battery and a voltage divider and regulator, that was microprocessor controlled and one could patent this method, perfect it, you'd be sitting on-top of a couple of million dollars?

She smiled, showing white teeth and blushed at the fact that I had recalled her first conversation with the check-out girl.

But said that she would, if she could give it a try.

I'm not a stalker of young wimen.

However, I am an opportunists, in the fact, that when I see and opportunity to develop a project, I will take this route, even at risk.

I somehow know, that the idea I had given her, she might consider and possibly on her own develop this concept, with respects as to how expensive petrol fuel is becoming?

I hope that she will peruse my idea and develop this concept, as we on Earth, can not depend on petrol based fuels forever.

Solar cells are actually very standard and Nasa by NO means has a monopoly on the most efficient ones. so I ask you.

PROVE IT!
 
Your'e a moron. I saw the special on them and they are very high quality.
Well, he's not a moron. Far from it. But I do agree that the latest NASA solar cells are more efficient than the current generation on the market. I've got 33 solar cells of the 2003-technology genre on my roof. I get a check for about $250 from the power company every year instead of paying an electric bill. If I were to have the new NASA cells in place of the ones I have, I estimate I would be getting about $270 a year. They are more efficient, but solar as a whole is still only in the 10-20% efficiency range. I seem to remember reading an article that said current market technology is in the 12-14% efficient, and that the NASA generation of cells bring it up to 20% and above.

As I pointed out to Creedo before, this is not good enough to act as the sole power source of a passenger vehicle. It would work well as an energy-saving augmentation to an existing gas/electric hyrbid vehicle, but solar could not handle the job alone for a consumer car. I estimate about another 10 years before we see solar power conversion getting to the 40% efficiency levels. Just my guess... /ttiforum/images/graemlins/smile.gif

Thank you, point proved. If you want to go on Cost alone of solar cells, a new company has some sort of plastic/silicon based cells that generate and 2-5% efficiency. What makes them special is they are flexible, and will be dirty cheap. I'd rather have millions of these than a few very expensive but highly efficient solar cells.

Nasa doesn't have the most efficient cells, they have much more efficient cells than are available to the general public, but per This link it looks like the world record holder is a company in California. HERE

although most of these will be bound for outer space, they are not neccesarily only for Nasa.

They have cells 36% efficient and approaching 40%.

My only point, Nasa does Not have the most efficient cells, although they probably do have access to them from an outside company, that outside company is not government controlled and these could be purchased commercially if you had the $$$
 
Ren' good find, thank you?!

The reason solar cells will have to be cladded to the new energy saving vehicles, may be the following.

I am working on the source of this report, for another board.

However in an energy saving vehicle, that ran out of gas, there was also a reported loss of this computerized power fed vehicle's system configuration loss.

In other words, when they filled this vehicle back up with gas and turned the key, ((no system configuration)), as the auto's computer, had lost configuration; no memory?

So in order to keep some of the computers configuration online and avaible when wanted, there must be another form of power, that will always be a power source to both charge batteries, and to keep some of the active electrical components running.

Not for this sole purpose, however small items such as a cadmium system config battery, which affords motherboard system configuration to memory, is sometimes forgotten.

These vehicles should become more and more complex, as time goes on.

Somewhere, in some garage, there may also be a self tinkerer, that builds an Alpha vehicle, that contains all of what I saidl however without the factory luster.

Other sources of power, to feed the little items is what is needed.

_RMT and the power of worms as a threat....?....Mmmm, I can never tell when your kidding.

It took me a while to catch this.

Well, that can be attributed to nothing more than VERY poor design! There are all sorts of non-volatile memory technologies that can store and hold data without need for any power at all. The most common, and the one we use regularly in aerospace vehicles, is flash E-squared (Electrically Eraseable). It only requires power when you want to rewrite data into any given memory location. But once power is removed, the last data written remains for the next power-up.

LOL I was going to say the same thing. Flash Memory can store its information almost indefinitely without any need for a stored or constant charge. Which is why when I turn my computer off at night and on in the morning I don't have to reload the bios and cmos. And even if you remove the cmos battery all you will lose is the system time.
 
Edit note, Rainmantime's added queue, on aerospace quality flash memory.

Some aspects of aerospace appliances and electronics, in the original design of this Japan based product, may not have been accounted for, as some of the orients main auto industries, are open to them, only.

So a proper design, might include a battery of flash memory modules, which solid store system configurations, of the non-powered auto vehicle.Mmmmm__mmm, cost??

This is so if power is absent, then at a later time, more acceptable morey could be used to reestablish the auto's system configuration.

The newer hybrid vehicles, at this time, are heavily depend upon electronics, in order to achieve the performances they want.

So a more liberal resource poll, in order to obtain the right electronics, may at times be a problem for some of these auto design companies?

Cost? Flash is CHEAP.

I agree with you on this statement. Hybrids do depend on more electronic equipment than a noraml car to achieve higher performace. So what? Thats like saying, the Sky is Blue and the Sun is Yellow. This is obvious.

I doubt it, any electronics in a car are based off silicon transistors, which are dirt cheap. They can even take a pre-made Silicon chip and then program it accordingly.

As always, I ask you to prove your absurd statements, back it up with facts, give us some links.
 
It is nothing more than this:

The system design engineers for automotive electronics applications are simply learning the same lessons we learned in the 1st and 2nd generation fly-by-wire flight control system designs. They simply "goofed" on some design aspects, like providing a non-volatile means for the vehicle to store its configuration, as well as realtime data for its tuning.

I've worked on aerospace systems that generate and retain a lot of data and information related to their realtime operation. Certain system states and measurements need to be retained as the system operates and as its physical components degrade in performance. This drives an eventual requirement for any intelligent control system to have a "persistent" form of memory. It needs to track and memorize its critical performance parameters as it matures.

Any different than the human being? No, not really. But we are learning how to build human memory and therefore performance enhancements into intelligent machines these days. And this capability will continue to increase and improve in the years to come. Just you wait and see!

I consider myself a control systems engineer who is lucky enough to live, work, and develop in the "stone age era" of intelligent control systems. I've been taught my craft of control system design in such a way as to venerate a linear, predictive control system. Yet the true future of control systems promises highly efficient and effective control systems which will be non-linear, and therefore non-deterministic, in their operation.

When our technology advances from linear to non-linear control systems, we will all notice the difference in terms of energy efficiency. It will make us look back on the oil dependency days and wonder what the hub-bub was all about.

Creednosaurus answers; No actually Ren, the sun is white and the sky is now tinted red.
In order to prove this to you, look out an auto vehicle in the countryside, that had a blue tint, to the upper part of its windshid.

Wear a pair of amber sunglasses also.

What you will see, is the sun now burns white and that there is a red ring, that is margined around that sun?


Ren said> I doubt it, any electronics in a car are based off silicon transistors, which are dirt cheap. They can even take a pre-made Silicon chip and then program it accordingly.

Creedo replies:Never said that Ren.What I had implied, is that because the Japanese practice exclusivity, within their business practices, that they don't always margin manifesting items made from other parts of the world.

Japan does not always practice a free world trade, per item margin.

So you will find allot of items placed on Japanese autos, that are gennised from their sole auto manufactures consortiums.

Or' don't you know much about Japanese manufacturing practices?

Oh Ren' you made two typos in your first sentance groups, that I did not correct, when I proof read this post.

Oh Creedo, while attempting to tell me about my typo's, you couldn't even get the word sentence correct. that's kind of funny.

Wear a pair of amber sunglasses also.

What you will see, is the sun now burns white and that there is a red ring, that is margined around that sun?

and if I wear a pair of all Black sunglasses maybe I can block you out of site.
 
That seems to be your solution. Threaten, have your friends physically threaten me, and then try to have me booted off the boards because we Differ in Opinion.

Again, this proves my point exactly. I am willing to backup my opinions based on fact, you will not backup your opinions and when someones opinions differ you threaten them. Come on, how mature is that?

I welcome all of your posts, I will continue to ask you to prove your assertations. and even if I am gone for good, there will be others who find the flaws in your logic and ask for proof. Getting rid of me will not get rid of the flaw in logic. Please quit threatening me and take it up with me by posting your opinions and possibly prove some of your facts.

Trust me nobody on here will be offended if you backup a statement with a fact. I know MOP will see and understand the nature of the debate between us. and that is why I consider this an ongoing debate. If you are incapable of handling conjecture, and you want me kicked off that badly, then I beg MOP to kick us both off instead of just myself as only that would be fair to the other posters on this fine board.. =)~
 
Doesn't this just take the cake?

First you corrupt my thread in Claims, then you go out of your way to take shots at Creedo all over the board. There's a difference between differing opinions, and taking digs at someone. If you truly give a damn about the Love of All Things Great, you'll learn to shut the [censored] up and let the grown ups talk for a change without interrupting or contributing on matters you do not understand.

Stop being an asshat!

I thought I contributed quite a bit to this thread. Others as well, sorry if you didn't see it that way, I'm done taking shots at creedo its not worth the time. He can have his fiction threads I'm more interested in reality than fantasy.
 
A way to look at this new energy vehicles now, is that if all gas would disappear now, in two years time, how would you get around without it?

You would have no alternative, but to learn how to build you own vehicle, using a series of batteries, solar cells, E-power controls and other features.

There would be no choise in the matter.

So what do you have now?
