Raman's team has developed a potential solution: a simple thermoelectric device that generates power when it's exposed to the cold night sky.

一种暴露在寒冷的夜空就能发电的简单热电设备。

Then, the exhaust heat from the bottom plate of the thermoelectric device would be used in the traditional way to warm water up.

其次，从热电设备中位于底部的薄片中出来的排气可以用于传统方式来加热水。
