More Efficient Carbon Fiber Airplanes

Boeing has just done a test flight for their new 787 Dreamliner. I usually don’t fawn over a big corporation’s newest product launch, but this one is a highlight for efficiency. It is mostly made from carbon fiber composites and titanium, uses more efficient engines and should save an airline 20% on fuel costs.These fuel savings will constitute huge reductions on greenhouse gas emissions since flight is one of the most CO2 intensive activities one can pursue. A couple percent savings with the largest wasters can have a bigger effect than a huge savings in less wasteful sectors.

Amory Lovins of RMI has presented evidence linking energy efficiency with improved profits at some major corporations. There are now sustainability MBA programs at institutions like the Presidio College that are training the next generation of managers and executives. This profit oriented demographic will uses their newly acquired efficiency paradigms to drive the more forward thinking corporations towards sustainability as a competitive strategy. And being less competitive will quickly drive the other corporations towards efficiency. As Lovins says, “We will change their minds or their managers.”

Companies like FiberForge will be cranking out the new ultra-light, ultra-strong materials to meet an ever rising demand. A concept I would find conceptually appealing would be generating some of those carbon fibers from CO2 emissions. To sequester carbon within the industrial materials that will reduce the CO2 emissions has a kind of intellectual symmetry that is very satisfying.

Volkswagen 1 Liter Concept Car

With a super lightweight and aerodynamic carbon fiber body weighing in at 660 pounds and a small fuel efficient engine, Volkwagen’s new concept car, the 1L,  can go 100km on 1 liter of gas (Hence the name) or approximately 235mpg. It is scheduled to be produced in limited numbers in 2010.
