Nanocar
Prof. James Tour /*who is Professor of Chemistry, Professor of Computer Science and Professor of Mechanical Engineering and Materials Science (what a combination) */ and his group have built World's first single molecule car.
Michael Crichton in his novel Prey writes about nano-factories that produce nano-assembly units to mass produce other nano-agents. It seems that the nano-technology world is not only moving very fast but will totally revolutionize the way we live. India still has lot of catching up to do in the world of nano-technologies.
Sidebar — In 1987 movie Inner Space Dennis Quaid shrinks a huge motorized vehicle to a microscopic size to get injected into human body. Well now, with nano-technologies we will have technology to build such vehicles molecule by molecule.
