It's made possible by a phenomenon called radiative sky cooling.

这是由“天空辐射冷却”现象实现的可能性。

As heat leaves an object, it becomes cooler, a process known as radiative cooling.

热量离开物体时，物体会变冷，这一过程称为辐射冷却。

So SkyCool designed a new material with radiative cooling properties that work 24 hours a day.

因此，SkyCool设计了一种具有辐射冷却特性的新材料，可以24小时工作。

The radiative cooling, in the sense that we're doing, has really never been out there before.

辐射冷却技术，像我们现在做的这样，以前从未有人做过。

An important limitation of radiative cooling has long been its relative ineffectiveness by day.

长期以来，辐射冷却的一个重要限制是它在白天相对无效。

Another challenge posed by radiative cooling systems is that water needs to be wiped off the surface of the collection chambers.

辐射冷却系统带来的另一个挑战是需要擦去收集室表面的水。

You can see there's just a really stark contrast in -- in temperature between the surfaces that are -- these radiative cooling found and the roof of the building.

面板表面和建筑物房顶的温度之间对比非常鲜明。

A key way to do this is with radiative cooling, a phenomenon that occurs at night when certain materials (like aluminium) radiate enough heat to cool below the ambient temperature of their surroundings.

实现这一目标的关键方法是辐射冷却，这是夜间发生的一种现象， 某些材料（如铝）辐射出足够的热量， 使其冷却到周围环境温度以下。
