IBM unveils computer fed by 'electronic blood'You've probably heard o
You've probably heard of Moore's Law that has predicted that the number of transistors on integrated circuits doubles approximately every two years. The problem is that we are nearing the physical limits of our ability to miniaturise these circuits. Our current solution is to stack chips to make multi-chip cores. The problem with this is cooling the chips, which tend to get very hot. The BBC reports that IBM are developing a novel approach in which a fluid of vanadium is used to both power the chip and cool it simultaneously. The advantage of this is that the design doesn't need two separate circuits, one for power and the other for cooling. This IBM scientists state is inspired by the brain where our blood provides both energy to the brain and cooling, resulting in a very efficient system.
