Their detailed design (again conceptual) provides for about 1020 logic gates per liter and would operate at 100 MHz resulting in up to 1028 computing operations per second per liter of computer volume (though heat dissipation would require that this volume have high surface area).60 The amount of power expended by this design would be on the order of one hundred watts.61 Since there are around eight billion people in the world, emulating the brain computation of all human beings together would thus take fewer than 1024 operations per second (1014 per person times 1010 people).
