Cars made of Biomaterials

I was glad to read today that it appears there are some advantages to the price of oil going up. The automobile industry is trying to lower their use of petroleum-based plastics and composites; to replace them with biomaterials which are lighter and "greener". A lighter car consumes less fuel, a greener car generates less carbon dioxide. It is reported that substituting 1 tonne of conventional plastics with its "bio" equivalent eliminates 3 tonnes of carbon dioxide. WOW! It is predicted that in 2015, each car will have approximately 200 pounds of biomaterials... I am telling you, the "organic" car is just around the corner :)
