求翻译：A Type II civilization, for example, consumes all the energy that is pro¬duced by a star. Let us say that its engines are 50 percent efficient, meaning that half the waste it produces is in the form of heat. This is potentially disastrous, because it means that the temperature of the planet will rise until it melts! Th是什么意思？ 待解决
