Elevator to anywhere on earth!

Ok, you found me out - when I get bored I sometimes look for strange stuff on YouTube. I got this link, that has science fiction written all over it, there that describes the craziest elevator of all. One that could take you anywhere in the world, in 42 minutes. Press play

Other than the obvious objections, there is one that they missed. The system is not without it's losses. If you don't add energy at the start or near the end, the "elevator" can't come all the way to the end. Just as in a pendulum swing, there is a loss that has to be addressed or the capsule is going to end up stuck at the center of the earth!
