Another interesting quote: > We estimate that a system with 10^11 active 10μm x 10μm elements (comparable to the number of neurons in the brain) all firing with an average pulse rate of 1KHz (corresponding to a high neuronal firing rate) would consume about 50 watts. The quiescent power drain for this system would be 0.1 milliwatts. Note they are referring to 10μm process technology. Modern state of the art technology would probably get the power consumption of such brain scale system down to under a single watt.
