That's not going to solve overpopulation problems here, because it would be cheaper to feed someone for life (ie it would require less energy) than it would be to send that person outside of Earth's gravitational field.

There was an error in my calculations, which are based on freshman college physics I took in the 90s, so never mind.
Attempt #2:
Gravitational potential energy = kinetic energy = .5massescape velocity^2. = .5human bodyweight kg 11,200 m/s. Convert the units and you've got a few years worth of calories (which I think I mixed up with kilocalories the first time).
