Present day silicon based microprocessors work by moving electrons around a circuit. This results in generation of lots of heat due to resistance, which ultimately results in wastage of energy. According to an analysis by University of California, Berkeley's electrical engineers, they say; future computers may work differently, relying on magnetic microprocessors that consume the least possible amount of energy allowed by the laws of physics (thermodynamic laws).
In the future Microprocessors employing nano-meter sized bar magnets for memory, logic and switching operations theoretically would require no moving electrons.
