My vision of an MBrain is that it works more like a super unified community than as a massive single brain. It could have structures within the MBrain that operate in a way analogous to our cities and corporations, that do things interdependently and independently of the rest. If we use the dimensions I suggested for an MBrain in an engineering society presentation I made last fall, assume a ring of nodes spaced one meter apart in orbit at 1 AU. That ring contains about a trillion nodes. Those trillion nodes can communicate with each other by passing signals serially along the ring. Another ring outboard of that one would be analogous to a second city or corporation. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>As we move outward from the sun, the rings have more nodes but less energy falling per unit area on each node, so the optimum design differs. In that way, the MBrain forms another analogy to our modern world: we have a few of us who use energy like crazy and do a lot of things which impact everyone else on the planet. We, everyone reading this comment, are analogous to the MBrain nodes which orbit close and collect a lot of sunlight. Do cool stuff with that energy.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>spike<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p></div></div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p></div></body></html>
