I know American Airlines is suffering badly because of fuel costs. It will take a great engineering feat to bring airplanes into the fuel efficient era. It will involve many disciplines. I hope they can pull it off! Wing design, engine design, electronic controls, fuel mixtures, and who knows what else, will make it happen. I am sure they have things in the "wings" that will surprise us all!
As I recall, the 787 offered a 20% fuel efficiency boost over the 767, but I believe it required the biggest engineering effort in the company's history. Given that, 10% to 12% seems pretty good.
From the article, I got the impression that the majority of the savings were aerodynamic related. I did see weight reduction mentioned also (for the fly by wire change), but the design changes didn't seem to focus on removal of weight.
From the picture and the article, I also noted the larger engines that are now directly attached to the wing (which appear to be a noticeable change from the older 737's that I remember when I was younger).
You probably know way more about this than I do, TJ. I was just thinking in terms on how inefficient automation devices and vehicles were in the past. So it seemed there must be significant gains to be made one you concentrate on energy savings. As an example, efficient motors and drives are driving down energy consumption 15 to 35 percent. Perhaps Boeing was not so inefficient going into the drive for efficiency.
I'm a bit surprised the re-design would only yield 10 to 12 percent fuel savings. It seems that number of changes would produce a greater savings. Perhaps the earlier models were already designed for efficiency.
A new battery design, which replaces lithium with abundant and low-cost elemental sulfur, is still in its nascent stages but shows real promise for giving batteries more energy potential.
PTC will offer a virtual desktop environment for its Creo product design applications, potentially freeing engineers to run them from remote desktops on a variety of operating systems and mobile devices.
The push to achieving more intelligent, integrated manufacturing is putting a strong focus on networking and connectivity as key enabling technologies.
Now that solar and wind harvesting technologies are a thriving market, researchers are seeking other environmentally related energy sources for which they can create harvesting devices.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
