black is the new ‘green’
(SPACE.com) — A new study finds that supermassive black holes, located at the heart of some galaxies, are the most fuel efficient engines in the universe.
“If you could make a car engine that was as efficient as one of these black holes, you could get about a billion miles out of a gallon of gas,” said study team leader Steve Allen of the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University.
“In anyone’s book, that would be pretty green.”

“Once gas comes within a distance about a million times larger than the event horizon of the black hole, it becomes gravitationally captured,” Allen explained. “At this point the gas becomes fuel for the black hole engine.”
