In addition to all that's clean and essentially renewable as to the
evengy existing between Earth and our moon (2e20 joules or better),

Insolation (space): 1350 W/m^2
Total lunar surface area: 3.792 * 10^13 m^2
Facing lunar surface area: 1.896 * 10^13 m^2
Albedo: 0.12
Phase corrective factor: 0.50
Total available power: 1.536 * 10^15 W
Total Earth surface area: 5.101 * 10^15 m^2
Earth disc projection: 1.278 * 10^15 m^2
Orbit semimajor axis: 3.844 * 10^8 m
Total Dyson Sphere surface area: 1.857 * 10^18 m^2 (4pi steradians)
Facing Dyson Sphere surface area: 9.284 * 10^17 m^2 (2pi steradians)
Earth span in Moon's view: 8.649 * 10^-3 steradians
Earth power intercept: 1.867 * 10^12 W

Moon mass (M_m): 7.348 * 10^22 kg
Mean moon velocity: 1.022 * 10^3 m/s
Orbital escape velocity: 1.445 * 10^3 m/s
Delta velocity (v_d): 4.233 * 10^2 m/s
Moon orbital energy: 3.837 * 10^28 J
Chemical v_e: 3 * 10^3 m/s
Final mass after burn: M_f = M_m/exp(v_d/v_e) = 6.381 * 10^22
Required fuel: 9.670 * 10^21 kg
Saturn V F1 fuel flow: 1.06 m^3/s (estimated)
Saturn V F1 mass flow: 1.06 * 10^3 kg/s (estimated)
Time to eject moon from Earth using 1 F1: 289 billion years
Time to eject moon from Earth using 1,000 F1s: 289 million years
Time to eject moon from Earth using 1,000,000 F1s: 289 millennia
Total number of Saturn V stages built: 45
Total number of F1 engines built: 75 (estimated)

Practicality of moving Moon out of orbit: 0
