UNSW researchers set world record in Solar Energy efficiency, by converting 40% of the sunlight power into electricity.
Rainbows exhibit the colors we’re all familiar with when they’re not at their highest position in the sky. As the Sun sets, rainbows arch higher and higher without much of change in color. However, once the Sun dips below the horizon, the increased path length of sunlight alters a rainbow’s appearance. Image credit: Phil Thomson; Phil’s Web site
