After the invention of the Nanomotor in 2003, the way we looked at mechanics as we knew it changed. And now the first chemFET has been invented. For people new to the field of electronics, chemFET = Chemical Field Effect Transistor. The links provided might just be a good start into knowing the potential we might harness soon. For example, a Nanotube has currently been tested for a strength of 63 GPa's ven High Carbon steel has 1.2 GPa.

And considering that UK just sucessfully cloned a human embryo, we might well be getting into the "Star Trek Generation" !!
