You're right, of course; I was aiming at humor. In any case, I would think that it would make more sense to use the sun's gravitation as a whip, so that at 3000 km/s one could not only get around the sun in a few hours, but also be far enough away to handle the sun's heat and its other radiations.
Escape velocity from the sun at the earth’s orbit is 44 km/sec. An object traveling at 3000 km/sec would escape the solar system (and the Milky Way) and never be seen again. The whole concept is idiotic.
