Scientific breakthrough makes LEDs way more efficient

[Retro]

Did you know that even the best LEDs are only about 40% efficient? This is because a lot of the light that they generate gets reflected back from the surface or absorbed as heat. Now scientists have discovered how fireflies have such high efficency with their light emissions and applied that knowledge to LEDs, creating much more efficient ones. Watch the video for the fascinating details of how scientists once more learned from nature.

Fascinating stuff; just goes to show, we still have a lot to learn from Nature. Test tubes and laboratories are essential, and we should utilize them to uncover the efficient workings of the natural world.
The more you watch and study the natural world, the clearer it becomes that efficiency thru the conservation of energy is paramount.
