A new type of transistor is being developed that can enable computers 2000 times faster than they are today. Read the full article Here
This transistor will run cooler and use far less heat than regular ones as it works not by starting and stopping the flow of electrons but by redirecting a stream of them. The article states that just one electron is needed to identify a 0 or 1. The possibilities are incredible. They have already produced a prototype that although huge is nearly as small as a normal transistor. If they can manage to shrink it down to work on the single electron scale you could have multivac in a Matchbox.
