The Penrose process may offer a way to gain energy from the ergosphere, although it would require the spaceship to dump some "ballast" into the black hole, and the spaceship would have had to expend energy to carry the "ballast" to the black hole.

但是彭罗斯机制或许可以为飞行器从能层中获取能量,虽然这个过程要求飞行器必须将一些“压仓物”抛入黑洞,这样飞行器也必须损失一部分由“压仓物”所携带的能量,这部分能量则被黑洞吸收。
