3-D microchips for more powerful and environmentally friendly computers

Not so long ago our computers had a single core which had to be boosted for performance - making each machine into a great central heating system. Beyond 85 C, however, electronic components become unstable. To overcome this physical limit, a solution was found with the multicore technology, where the same chip includes several processors which share tasks. Most of today's consumer electronics proudly boast a 'dual core' or 'quad core.' However, in time the technology will come up against the same physical limits...
