So that would be really great, if you could add that to the production capacity in Tanzania. It would really boost the economy. 3) F. Now, how much putation does the brain do? I estimate 10 to the 16 bits per second, which is actually about very similar to what Blue Gene does. So that’s the question. 4) T. So what we are doing right now with puters with the energy consumed by 1,200 houses, the brain is doing with the energy consumed by your laptop. 5) F. How does that pare with the way puters work? In the puter, you have all the data going through the central processing unit, and any piece of data basically has to go through that bottleneck, whereas in the brain, what you have is these neurons. 6) T. This is something that we’ve been working on for the last couple of years. 3. 120,000 processors 10 to the 16 bits per second megawatts 10 quadrillion bits per second 10 watts 4. Although puters have strong power to process data, they still cannot pare to the brain of human beings in which an unbelievable number of neurons connect and react with each other so that a real net could be acplished perfectly. The research on how the puter could be as powerful as a brain will continue going on.
