Really? I must be misunderstanding something then. The Earth-Moon L1 point is ~63 km from the Moon. Let's say me and my gear weigh 200 lbs, and the Moon's gravity acceleration is 1.62 m/s^2. 63 km * 200 lbs * 1.62 m/s^2 gives a potential energy of only 2,213 kcal. The human body is only 18-26% efficient [0] at converting food into energy, so we're probably looking at around 10-13,000 calories. Depending on what you're eating, that's 4-10 lbs of food. Obviously, I'm ignoring the time it would take to climb that far, but in terms of energy, it seems reasonable that a human could carry enough good with them, unless I'm gravely misunderstanding something. I'm guess that assuming "potential energy" means "the energy needed to move X pounds to Y height at Z gravity" is incorrect.
