There is another possibility you could try and that is employing an electrodynamic tether. https://en.wikipedia.org/wiki/Electrodynamic_tether https://en.wikipedia.org/wiki/Electrodynamic_tether As the earth's magnetic field reaches the moon a lunar space elevator tether could be constructed to intersect this planetary magnetic field. This giant wire then acts as a dynamo to convert the kinetic energy of the moon to electrical energy. By slowing down the moon you can create direct electrical current. How much current is dependant on how long the tether is and it's internal resistance. Try the back of the envelope calculations. This would be a rather large figure.
