Heat generated by a data centre could also be used to more efficiently process the animal waste and thus increase methane production.

由数据中心所产生的热量也可以被用来更为高效地处理动物粪便，从而提高沼气的产量。

The devices may be used to cool electronics, harness solar energy in a new way, and conserve energy by changing waste heat into electric power.

这种装置也许可以用来为电子产品降温、把余热转化为电能，或者是一种利用太阳能的新方法。

Because of this, it could be used to convert waste heat energy into large amounts of electricity.

正是因为这样，它可以用来把废热大量转换成电能。
