'Halo Drive' Would Use Black Holes To Power Spaceships

The major drawback of a halo drive would be that 'one has to travel to the nearest black hole,' Kipping said. 'It's akin to paying a one-time toll fee to ride the highway system. You have to pay some energy to reach the nearest access point, but after that, you can ride for free as a long as you like.' The halo drive works only in close proximity to a black hole, at a distance of about five to 50 times the black hole's diameter. 'This is why you have to travel to the nearest black hole first and [why you] can't simply do this across light-years of space,' Kipping said. 'We still first require a means to travel to nearby stars to ride the highway system. Kipping is now investigating ways to exploit other astronomical systems for relativistic flight. Such techniques 'may not be quite as efficient or fast as the halo-drive approach, but these systems possess the deep energy reserves needed for these journeys,' Kipping said.
