A technology that originates from an invention by Thomas Edison in the 19th century — a bulb filament made of carbonated bamboo — is now considered one of the keys to curbing global warming.

Today, the extremely thin fiber is made of carbonated acrylic fiber, and while it is 10 times stronger than steel it weighs just one-fourth as much.

It is widely used for aircraft wings and fuselages, as well as for automobile parts, contributing to a drastic reduction in their weight and carbon dioxide emissions.
