That
the spherical centers of Trade Federation battleships can take off
from Earth would imply 63 megajoules per kilogram meted out in a
relatively short time. If a Trade Federation sphere is roughly 500
meters in diameter with an overall bulk density between 0.52 T/m^{3},
then we may
estimate 2.068.25 exajoules to lift it into orbit.
Given that Trade Federation spheres appear to require somewhere around
a minute to lift off into orbit, this gives us an effective power of
35137 petawatts that can be directed towards the repulsorlift systems.
