At last, someone with clue. But note the minor details missing in the url: price, and lead time. Plus, the 'last century' guy needs to do a little math. Sure we can store 50-500 joules. BFD. But the gap between that and that 768KV going flat out is many orders of magnitude more than between oh 110BPS and OC-48. The basic issue with all the power nets is really simple to grasp, in NANOG terms: Redundancy co$t$ -- who wants to pay?????? The power industry had no telecom bubble to overbuild facilities. It's easy to go from OC-48 to OC-96, right? It's far far harder to double the capacity of a 500 mile or even a 100 mile line. FIRST, there's the money. Then there's the politics. Only THEN do you hit the lead-time issue. And then.... And to put it another way... You have a buncha OC circuits, and get hit by backhoe fade. After you patch the fiber, you first have to junk the ci$co boxes at both ends because they blew up when the fiber broke. To restart, you then must get a sync signal from Hillsburo, get everything all on key & in tune, and then you start the smallest box, the next one, then finally.... Do it wrong and you get another Star Trek Bridge panel scene. -- A host is a host from coast to coast.................firstname.lastname@example.org & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
