OP's free energy doesn't exist, or he didn't explain it clearly enough.
But he's on the right track, gravity SHOULD be a part of long distance travel, especially if we can do away with friction losses such as hyperloop set its mission to. I'm disappointed by their move away from as full a vacume as possible. Pods can be built to deal with it (ISS famously does so on Russian duct tape), and pulling the vacume will save energy in the long run similarly to insulating a house reduces a heating/aircon bill.
