really ?
looking at _production_ cars:
Toyota Prius from 2009: drag coefficient: 0.25
Tatra 77a from 1935: 0.21
Rumpler Tropfenwagen from 1921: 0.28
the late 30ties were actually the high point in aerodynamics being the focus in automobile manufacturing: there are countless of other examples from the time which simply never made it into production because of the war:
like the BMW K1 prototype which also achieved a value of 0.23 despite being a full 4 door saloon
another interesting car: the Fiat Turbina prototype: which had a coefficient of 0.14 (a record for 30 years) but any further development shelved because of problems with the expieremental fuel gazzling overheating turbine engine ;)
Thanks! That was fun following up on some of these early cars. Some of them are just gorgeous. It is amazing and inspiring that engineers working with slide - rulers and wind tunnels (and without fancy computers) could achieve the same kind of drag coefficients on their designs that modern supercomputers can come up with.
However - I still think my point stands ("Steadiness"). While small production cars may have been aerodynamic - the industry average was not. In fact I could argue that as engine efficiencies improved, industry wide, aerodynamics got worse because the overall mileage stayed much the same (or improved slowly).

To quote someone else in this thread "show me proof", in terms of actual statements given under duress and the results of that information. Until you or I see that we are both really just hand-waving...
indeed, but if those in favor of EI can't actually show some support for the claim that it's actually useful, then it seems to me the argument in favor is reduced to one that's basically an emotional response. That doesn't seem to me to be enough to justify using EI
....As for the guy in the video, he's really the only one out there that I have seen that is so vocal about the ineffectiveness of E.I.....
I don't think that's true at all. During the Bush years there were quite a number of people from the intelligence community that said the same thing. There comments were the usual basis for responses to "show me proof" to refute the idea that EI is useful

Why should people who just want to read the news be compelled to provide the FT with personal information in order to do so? Why does the FT need to know my name, address, phone number, etc.?
Why does Apple need my phone number? I just want to buy and use their products? (For an Apple ID, ie, if you want to use any apps, even free ones, Apple requires you to give them your personal data, in Apple's stores, they even ask for your ZIP code when your purchase anything, well at least in those stores I have been.)

Every time I see a blood drive my blood just boils... As an HIV negative gay man who is in a monogamous committed long term relationship with my partner, I doubt I am any more of a risk then any other heterosexual couple in a relationship, yet they don't see it that way....

Ok, so it isn't original. But do you have any idea how long it took me to get that right?
By the way, whoever can guess which favourite game of mine this avatar is from, will get a free box of cyber cookies :D

You are/were 1 to 2 years late with putting out this Verizon iPhone.
Android has gained adoption...
Don't worry, you will be fine in the long run - a Verizon LTE iPhone 6 will get your sales kicked in within the Verizon market. I know I will be going back to an iPhone when it happens. :cool:

Warranties transfer, but they (of course) run out a year after the original purchase date, not the resale date.

thanks! I was hoping however that it would be a free solution. :(
I don't remember paying anything for those. Look them up if you have the time. If I knew how to take just the icon out of the set and post it, I would. Sorry.

First let me say while this is a new account, I am not new to Macrumors. I've been coming here for a while, it's just now that I am making an account.
Ok, some of you might be aware of Mountain Dew/Pepsi's promo, every10minutes where you can win an Xbox 360. If any of you drink this regularly, instead of simply throwing away the caps, I'm asking you to email them to mikeL30@gmail.com
I know it sounds like a lot and sorta cheap, but I'd really appreciate it and if I could give something in return, I would

I can't see apple employees driving around remapping the world to get their own data base
No need. Apple would just license the map data from either Navteq or Tele Atlas. The map data that Google uses at present is TeleAtlas (Especially for Europe).

Woot. Looks like eBay cancelled the auction!!
no dude, read the thread. HE cancelled it. you can still see it in completed auctions as ended by the seller. when ebay cancels, it goes *poof*.
