In the future, I think people won't be worried about travelling because of teleporters. It will look like a big magic box or maybe it will be designed as a magic lift. In my opinion, it will be powered by solar energy and it will combine the function of a 3D map. Just think about going into a teleporter in France and choosing Vietnam as the destination. Then, 3 minutes later, you will be in Hanoi - Vietnam. That will be great. People can use it anytime and anywhere. It won't take a lot of space. I think it will replace all other vehicles and it will make people around the world closer.
