You can take heat energy and convert it to work energy and vice versa, and it doesn't say anything about that you have to waste heat if you're going to transform heat into work.

你可以把热能便成功，也可以反过来，但它对于如果你要把热变成功，就必须浪费热量这件事只字未提，它只是说这是能量。

Electrical effect. Two different metals welded together can transform heat energy into electrical energy. This principle is used in the refinery to measure temperature by use of thermocouples.

电效应。两种不同的金属焊接在一起可以将热能转化成电能。在炼油厂，根据这一原则，通过使用热电偶来测量温度。
