Forget silicon and return to valves
 

Boffins looking for ways around Moore’s Law have decided that transistors are a bad idea and they need to go back to the vacuum tubes – read valves – of the early computers.

Of course, the vacuum tubes are a little smaller than those used in the codebreaking WW2 computers – those under development at Caltech’s Nanofabrication Group are a million times smaller.
