After a round of demos today, we did a brief exrecise to look at the budgetary relationship in a datacenter between the cost of lower-power replacement nodes and the power cost for the center. Witha 40% power reduction, the time to recover replacement cost would be just a few years. That could enable an increase in load capacity for the center, which could then translate into a more competitive price for services. 

Next week, there will be an open time during the final exam period, which is Thursday, 9AM to 11AM, for teams to update their demos from today, if additional progress has been made. We will use the usual class meeting channel for that. 

No new slides for today.
