最近，人们对一个大质量天体的引力坍塌问题以及“黑洞”的存在可能产生的天体物理后果产生了相当大的兴趣。广义相对论预测，黑洞有时应该是这种坍塌的结果。特别是，问题已经出现了，在适当的情况下，黑洞的质量能量含量是否可以成为可用能量的来源。我们现在考虑从黑洞中提取旋转能量，特别是因为黑洞的旋转能量(适当地定义)通常应该与其总质量能量1相媲美。
THERE has been considerable interest recently in the question of the gravitational collapse of a massive body and of the possible astrophysical consequences of the existence of the “black hole” which general relativity predicts should sometimes be the result of such a collapse. In particular, the question has arisen whether the mass-energy content of a black hole could, under suitable circumstances, be a source of available energy. We now consider the extraction of rotational energy from a black hole, not least because the rotational energy (defined appropriately) of a black hole should, in general, be comparable with its total mass-energy1.
