Wow, this is a very cool result:Researchers at IBM's Thomas J. Watson Research Center in Yorkstown, NY have announced a breakthrough which they feel could revolutionize power consumption in computers. Today's computers are power hungry: a typical computer consumes hundreds of watts of power. Not only does this power consumption add up to a lot of wasted power, but increasingly the amount of heat generated by the machines is a significant barrier to building faster more powerful computers. The researchers at IBM say they've made a breakthrough in how computers consume power which will…
