FBeans writes ""Scientists have shown off what can be described as the world's smallest electric car — made of a single, carefully designed molecule."
He continues, "The molecule has four branches that act as wheels, rotating when a tiny metal tip applied a small current to them."
Unfortunately it seems the car isn't going anywhere fast. After 10 electrical bursts it had only traveled six billionths of a meter. Further to this though, the car only works in -266C whist in a high vacuum. Dr Kudernac, the lead author on the paper, seems optimistic despite the potential road blocks that the single-molecule car faces.
"There are ways to play around," he said. "That's what we chemists do — we try to design molecules for particular purposes, and I don't see any fundamental limitations."
There is a long road ahead for this area of chemistry and it is yet to be know if there will be any real application of the smallest car in the world."
