“the ultra-low-voltage SoC technology is able to utilize innovations facilitating power generation via ambient energy sources, Wu pointed out. For example, thermo-electric generator SoCs can convert heat emitted from human bodies into electricity
The demonstration was at 65nm. If this can be done at 14nm, the future is now. CPUs will be able to run on trivial amounts of energy available from photo-voltaic, shaking or thermo-electricity. This will allow more throughput on mobile devices or much less use of battery-power. Pick whatever combination you want. Clients will become thinner and servers much more efficient.
