The Boeing 787 Dreamliner and the Airbus A350 airplanes are two early examples. What sets these planes apart from older planes is that their body and wings are made of composite materials rather than aluminum. They are more fuel efficient and fly farther. This reduces the cost of travel and opens up new routes. Passengers also enjoy benefits like increased humidity and cabin pressure. Humidity is increased from 4% to 15% and cabin pressure is increased from the equivalent of 8,000 feet above sea level to 6,000 feet above sea level. The bottom line is that these planes cost less to operate and provide passengers with ground level comfort and less jet leg.

Is it possible that the latest ‘wonder material’ has been under our noses the whole time? Could it really be derived from the most abundant organic polymer on earth, requiring only sunlight and water as production inputs? It sure seems that way. To paraphrase a friend of mine (out of context): Mother Nature has been innovating for billions of years and probably has it figured out.
