That's right we're running out of fossil fuels and asphalt - so lets build more freeways.  You'd think that in running an engineering magazine that Leland would have some knowledge of the materials problem.  You'd think he would know that several materials are running out.  Ones that engineers like to use.  But ...

The phsics quoted on the website is totally wrong based on personal experience and daily engineering calculations. The books are still right. Newton was brighter than anybody on this board. 

Maybe Lee Teschler should have spent enough time to read the report to justify the silly numbers.  It's HIS job to give us good information.   You didn't give any clue as to the missing dollars either.  How can there be such a large discrepancy.  I believe there is a post somewhere on the web that does go through the report ...

Could you please explain exactly how it costs over $300,000 to drive a Honda hybrid 100,000 miles.Who pays for what?I'm missing the accounting trick whereby Honda spends $300,000 for every car they sell.Yet another editorial with no backup for the numbers

So Lee,Have you come up with a justification as to why it's better to take almost new and clean recyclable materials like paper, cardboard, plastic bottles and the like which have high recyclable value and instead send them off to the dump to be mixed with dog and cat poop, babies diapers and the like? You said there would be no scary diseases? ...

But of course it's just fine to get in the old SUV and drive to the supermarket and pick up a 2 litre bottle of soda. No energy or cost analysis there!But recycling the bottle - whoa - cant do that.Chris P

Wind and solar did not ''work'' for Walmart because they were done for political reasons and not as a scientific endeavor. Sticking little windmills on a low building does not ''work. Except as a PR stunt.Apparently this analyst thinks that companies should never ''try'' things to see if they work. Apparently he quite forgot that Fedex was ...

I suggest you guys go buy a copy of Machinery's Handbook. All the engineers where I work are required to have one.Chris P

You haven't told us who made the coupling - can't you just look it up? The manufacturer will know the answer.And no it has nothing to do with gyroscopic forces. Chris P
