Magnetic PCs could use million times less energy

Coming soon- Magnetic computers which may use far less energy, say scientists.

A team at the University of California, which is developing such computers, claims that the future machines will rely on magnetic microprocessors which consume the least amount of energy allowed by the laws of physics.

Today's silicon-based microprocessor chips rely on electric currents, or moving electrons, that generate a lot of waste heat.

But microprocessors employing nanometer-sized bar magnets - like tiny refrigerator magnets - for memory, logic and switching operations theoretically would require no moving electrons, say the scientists.
