Carbon nanotube

It started as Bucky ball(think of soccer ball) in early 1980s. Some made it in a tube form(still much thinner than others so callled "fibers") in early 1990s, then layered. It seems like this can be grown into any shape, any size. Said to be much stronger than carbon fiber. I don't know exactly how it is going to be used in bicycle material but its prperty is way beyond just light and strong. People will experiment next 100 or 200 years just to find out what this material can do.

One use of this material I have heard of is that connect a satellite to a station on the ground with a ribbon made of carbon nanotube, use it as a rope to bring the elevator up and down between them instead of using rocket to go back and forth. Believe it or not, it's a serious project.
