Did you see this? According to an article here, Brazilian scientists are planning to build a greener car by making some of its parts out of fruit fibers. They have figured out a way to use the fiber from fruit plants like pineapples and bananas to reinforce plastics that are used to make car parts like dashboards, bumpers and body panels.
These “nano-cellulose” fibers are apparently just about as stiff as Kevlar, but come from a green, renewable source (Kevlar is made from petroleum).
By using this technology they will be able to make parts that are 30% lighter and 3 – 4 times stronger. Lighter cars means less fuel consumption. Greener manufacturing and greener fuel efficiency.
Way to go Brazil!
