World's smallest car fuels nanotech advance

There is a tiny nano sized car that can propel itself foward in response to electrical pulses in which scientists from the Netherlands had created this. This electrical powered vehicle is the shape of a single celled molecule that has a frame/chassis and has four paddle shaped wheels. This is considered the corner stone of nano technology. In order to make this tiny nano sized car to move, it needed a jolt of 500 millivolts.
