, we’ve learned you can make your car even more environmentally sound (*ahem*) by installing Panasonic’s newly-developed speakers, made partially out of bamboo fibers. Panasonic developed the speakers in conjunction with Doshisha University. Bamboo is one of the world’s quickest-growing plants, and apparently has an excellent sound range. Panasonic isn’t saying where these speakers may show up when they are released next year, but all signs point to a release for mobile audio systems. Most people listen to music in their car more than anywhere else, and even if the bamboo speakers cost more than other types (as Treehugger suggests), it’ll be a small price to pay for a somewhat more ecologically-correct automobile.
