Consider the following idea for inserting a human on the surface of the earth into orbit:
In orbit, attach a long (~80km) rigid shaft to a large weight (presumably an asteroid) and set it spinning. Alter its trajectory and angular velocity on a collision course with the surface, such that the shaft will briefly touch the person's harness on the surface with zero instantaneous relative velocity, and become attached.
As the apparatus continues spinning and falling, further rotation of the shaft carries our human up and out of the atmosphere. By detaching at apogee, our traveler achieves orbit, leaving the the apparatus to destroy itself in a collision with the planet.
Do plausible future materials allow it, and do the angular momenta work out?
