I have an idea the moon can be used to generate electricity. Build a railroad track all the way around the earth. The train on the track has generators on every wheel. Screw an eye bolt into the moon then connect the moon to the train with a long cable. The moon will pull the train that will generate electricity to the rails. All the houses on earth will be connected to the rails to get free electricity. Moon & Earth both travel the same direction the speed difference between the 2 planets is 37 mph maintenance workers can get on/off the train by truck and old/new RR cars can be switched on/off the train to side tracks easy.
