Hm... On the power necessary to keep the ship stable: Is this average power, or peak power? I'd expect average to be a small fraction of peak.

And homes don't use that much power. A car can use enough power to supply dozens of homes.

I wonder if they use a standard value for "homes?" ;-)

For what it's worth I recently heard a 50 MW powerplant described as enough for 100,000 homes ... so they think 500 watts draw on average for a home?

... and the 40,000 homes above would represent 20 MW

(though I know it's silly to expect a standard "home")

Not my house. Built 1931; Texas; 3200 sq.ft.
with an 1800 sq.ft. basement. 100 deg. days
in the summer = 8 tons of central
air conditioning.
