The question is, what gets power? Assuming you're the size of BBN, it
becomes.. er.. "physically impractical" to power everything with a
generator. I know when I was at RPI, though they had a room full of
batteries (3-5 minutes of power), and a huge generator, it was only
enough to power the telephone system and mainframe. In fact, it
couldn't handle the water cooler for the mainframe. But the point is,
even though (I hope) BBN isn't using a power-hungry mainframe, enough
routers, switches, NOC workstations, etc. will eventually add up to
more kilowatts than you can supply yourself. A decision has to be
made as to what stays on and what doesn't.
