e- They're going to be talking about this for weeks. We're going to get a lot of cool explanations about how the electric grid works (or is supposed to work). The most interesting property I seem to remember (from way back in they day, when I was an academic) about the North American electric grid is that it's a bistable system. That is, it has an "on" state and an "off" state, and the transition from one state to the other is typically a sudden, catastrophic thing. In biology they call it a switch. We read yesterday in this space that climatologists think this is the way ice ages start. It sounds, though, that we might just be looking at a switch in the most literal sense: too much power in the system, one circuitbreaker at a plant goes, thereby increasing the load on the rest of the grid, causing the rest of teh circuitbreakers to flip, too.

Free Sure, leasing a broadband connection with a Wi-Fi base is cheap. But add a billing system - secure login server, transactional database, credit card processing, tech staff, customer service operators standing by - and the outlay skyrockets to $30, $50, even $70 a day, particularly if there are lots of support calls. (Ironically, most of those calls will be about problems with the billing system itself.)Thank goodness Schlotzky's doesn't force WiFi users to actually eat its sandwiches---ick! On to Schlotzky's!
