    patentable tire idea?

    Response from Goodyear: Thank you for your correspondence dated October 13, 2005. This department administers the company’s policy with regard to unsolicited disclosures, or “outside ideas� as they are also known. Goodyear’s present policy precludes us from distributing...

    Hydrogen fueled vehicle using Mg?

    Out of curiousity, anybody have any idea how much work is required to pump up and refine petroleum? I'm assuming the numbers are different for say gasoline and diesel. I've seen some stats on biodiesel claim it produces about 30% more energy than it takes to "make" it (not including the solar...

    Hydrogen fueled vehicle using Mg?

    Yeah, the little diagram on their website might be missing a few items, like the amount of solar/nuclear/coal-fired energy it takes to refine, process, and shape those kind of metals.

    Hydrogen fueled vehicle using Mg?

    Interesting article on a hydrogen fueled vehicle... http://www.isracast.com/tech_news/231005_tech.htm Thoughts?

    patentable tire idea?

    I have an idea for a new "type" of tire that would likely increase fuel mileage (estimated 15+%) as well as either maintaining or increasing performance (relative to grip in the fore/aft and lateral directions). I've contacted Michelin and a few other tire companies and asked to speak to...

    weldability of case hardened parts

    Our welding engieneer consultant came back with the following: nitrogen should be held to less than 200ppm <150 ppm preferred anything >300 ppm will likely result in porosity Thoughts?

    weldability of case hardened parts

    I understand your recommendation. However, our company has managed to avoid the cracking issues common to the 1117 material for thirty years now. It's mainly the porosity issues we are curious about.

    weldability of case hardened parts

    We are welding an assembly made out of 1018 and 1117 parts. The 1117 part is actually heat treated prior to being welded. It is carbonitrided for wear resistance. We have occasional porosity problems that I believe are related to an inconsistent heat treat process and the resulting chemistry...

    New product development resources

    I'm fascinated by new product development. The cycles, the economics, the politics, etc ESPECIALLY in the automotive industry. I recently read -All Corvettes Are Red (details the years of ups and downs of the 5th generation Corvette development) -Product Design And Development (university...

    Objectively measuring and defining subjective steering &quot;feel&quot;

    Along with the steering "heft", I think there are some other characteristics that are sought after like - feedback - discernible play - accuracy - path accuracy Others?

    history tree not visible

    It actually sticks in my mind the first time I learned to toggle the tree on/off. I walked around for about two days muttering to myself... "F3 HIDES THE TREE, F3 HIDES THE TREE, F3 HIDES THE TREE"

    Objectively measuring and defining subjective steering &quot;feel&quot;

    I recently read an article on the new C6 Corvette and noticed GM got high marks for many things, but steering "feel" was not one of them. Many of the BMW's, especially the previous (mid 90's?) model M3, are widely touted as having nearly perfect steering. What is it about steering system...

    Seat cooling ala Infinity M45

    I'm curious how the seat cooling features like those found in a newer model M45 work. The car I saw did not use a draw-through ventilation system, it appeared to be some kind of eletrical function like a seat heater only in reverse... Any ideas? Anyone have direct knowledge about this system?

    1/4-20 'thread forming' screw

    I'm assuming you are replacing the bolt/nut combo with the thread-former as a cost savings project? You may want to watch the costs of assembly A vs. assembly B as you start adding in more part numbers. The part and labor costs may appear low, but it's one more p/n to order, carry in...

    Welding on radius of T-joint

    Metengr, thanks, I searched on that joint name and that's definitely it. Weldtek, I've tried to ascii diagram the thing below (again)with an X on where the weld would go. Strength is an issue. In some cases, both members are 12 gauge (down to .0966" thick), in some cases 10 gauge (down to...
