Congratulations goes out to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura. Some 20 years ago, they invented the blue light-emitting diode, an energy-efficient and environmentally efficient light source with revolutionary implications.
Here's how to turn a bar of titanium into a ring with LED-illuminated jewels that light up when they're near a power source. One: fall in love. Two: a bunch of other stuff. Three: boom, magic-ring.
Being outside gives us a sense of freedom and spaciousness, and as far as some German engineers are concerned, that means increased work efficiency. That's why they've invented a "dynamic luminous ceiling" that simulates working outside during a clouding day.

The best way to help alien visitors land on Earth would be to provide decent lighting around safe landing zones, figured Sevcan Yardim, a recent graduate from the Middle East Technical University in Ankara. So she got hold of some bamboo — a rarity in Turkey, but great for energy efficiency — laced them with LED light…
