Video: Bridgestone Airless Tires

Bridgestone's airless tire concept isn't new, it was unveiled a few months ago, but somehow I missed this video from the Tokyo Motor Show. It has a nice animation about how the non-pneumatic wheel works: specially shaped plastic spokes carry the load, and deform to absorb impacts.

 

There are major engineering challenges to be solved for designs like this, so these aren't exactly a few months or even years away from mass production. For example, how do you keep debris from getting caught between the spokes? How will the spokes do when hit with red-hot brake rotors in a repeat braking situation? What happens if you drive over a few large nails, which penetrate through the friction layer and into the spokes, will the wheel still perform?

These type of wheels do have some very interesting tuning possibilities. For example, they could have a different lateral stiffness (very high) than radial stiffness, so impact harshness could be reduced while keeping a sharp turn-in feel.

A few years ago, Michelin brought out a concept the called the Tweel (tire+wheel). After some initial publicity, the Tweel seems to have disappeared--I can't find any new news about it on Michelin's web site any more.

Anatomy Of A Scam: Nigerian Check Fraud

So you get an email from someone you have never met, offering you a "work from home job".  You get to keep a sizeable sum of money, in return for simply "processing payments" or some such thing.

If you bite, this is what will happen.

An blandly named fellow, such as "Mark Nelson", will arrange to send you a check, usually by FedEx or priority mail (to give it an air of urgency).

He will ask you to deposit the check, keep some money for yourself, and then split up the rest into smaller Western Union or Moneygram payments.

The reason they use Western Union is that it is not really traceable and can not be revoked. All they need is the Money Transfer Control Number and they have the cash, simple as that.

Then, your bank will sock you with fees and expect you to pay back the fictitious money.

Here we have an example where the package was apparently sent from Boise, ID.  However, using the tracking number on the label will show that it actually came from Pennsylvania!

Next, notice that the check supposedly was sent from one "Sarah Sparks", but it is signed by yet another character, "James J---" (it is hard to tell".  It is NOT signed by "Mark Nelson". And it was apparently purchased by "Tony Nguyen". 

The fake check itself is pretty good, however, you might notice small flaws.  For example, in this case, the ink used for the check account number, check #, signature, and other information was the same color of black and slightly raised (like a laser printer would produce).  There is no actual "water mark" on the check paper, when you hold it up to the light you only see printed ink.  Also, the "reflective ink" watermark that the front of the check claims is there is not in fact reflective, it is just yellow. 

Don't be fooled.   There is no such thing as a "work at home" job which pays $100's of dollars an hour for cashing checks and sending out Western Union payments.

Some Dart Thoughts

I haven't had a chance to drive a Dodge Dart yet (I'm not one of those big-time auto journalists, you know) but I did get a good look at them at the NAIAS, and also, I have been watching the launch publicity and early reviews.

Here are some thoughts.

The Dart appears to be Chrysler's first competitive compact/midsize vehicle since the Dodge Cirrus of years ago.  It has modern efficient powertrains, a nice interior, and nice gadgets.
It is a 100% improvement over the Caliber, which was, even after a refresh, a cheap rent-a-car.
Reviewers so far have been saying that the driving dynamics are quite good, and NVH is excellent.
Chrysler's weak spot now is quality and reliability.  They need to work hard to convince people that they aren't selling pretty junk.  Though, these days, even below-average quality new cars are quite a bit better than the average of just a decade ago.
I wouldn't buy a new Dart, yet, but I would not hesitate to lease one. 
The other part I'm not sold on is the front end styling.  It seems like a mish-mash of Dodge cross and more organic influences.  I actually like the basic monochrome version much better than the black bedecked Rallye trim.  The front overhang seems very long to me.
Still, this is the first car I have seen from Chrysler in a while that I could see myself owning.
