I think they meant composite materials that would give Boeing 737s at least 20% bettter FE than the current metal ones. They could be read within ten years.

speaking of plastic planes. What is going to become of plastic once the oil runs out? Can you make plastic out of other materials?

I think they just made an error when they said "new 737" in the lower part of the article. I don't believe there are any plans to rebuild the 737 as a composite airframe, although I wouldn't doubt it if they really did mean it. For a point of comparison:
Boeing 737-800: $70 mil, 190 passengers ($368k / passenger)
Boeing 787-3: $140 mil, 300 passengers ($466k / passenger)
So the 737 is still cheaper per passenger, at least in the varients compared.. the 737-600 carries around 100 passengers and is about $50 mil, which does not compare quite as favorably, unless you take in to account it's harder to sell out a 300-passenger flight than a 100 passenger flight. At any rate, I think it's extremely funny the 737 - an aircraft launched in 1967 - is still selling in large numbers to this day, and will possibly continue to sell in quantity for many years to come.

Didn't Henry Ford invent a plastic using soy beans back in the 1920's??
