British science fiction novelist Peter F. Hamilton has a very unique vision of how the world would work and operate if teleportation portals were invented. He spent 6 months hashing out how the world would be changed while working on his newest novel Salvation. Since we no longer need highways, they would be converted into parks and shopping centers. Hotels and motels would cease to exist as the trip from England to the USA could be completed in 2 minutes; thus a person would just sleep in their own bed. From irrigation to space travel, teleportation revolutionizes society's efficiency to the point where humans have to make a choice; spend a lifetime doing nothing or begin genetic engineering for higher intelligence. Teleportation might also allow humanity to easily explore the galaxy. Hamilton's interstellar starships are propelled forward by exhaust channeled through a portal. "You have one part of the portal that you just drop into the sun, and the other half is the rocket engine on the starship," he says. "No need for any antimatter or fusion or anything."
