史丹佛大學電機工程教授範善輝表示：這些面板包含一層材料，類似沙子中的物質。它就像一種高科技鏡子，既能將熱量從建築物中排出，又能反射太陽光線，並將熱量和陽光都送入 100 公里高的寒冷太空。

Stanford University electrical engineering professor Shanhui Fan said the panels—which include a layer of material similar to what is found in sand—act like a kind of high-tech mirror, both siphoning heat out of the buildings and reflecting the sun's rays, sending both 100 kilometers up into the coldness of space.

我又转念，见日光之下，快跑的未必能赢，力战的未必得胜，智慧的未必得粮食，明哲的未必得资财，灵巧的未必得喜悦，所临到众人的，是在乎当时的机会。

I returned, and saw under the sun, that the race is not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to men of understanding, nor yet favor to men of skill; but time and chance happen to them all.
