Jumping electrons inside crystals emit cold bright light
HERE’S THE INTERESTING PART
Incandescent bulbs wasted most of their energy on heat, so we invented a way to cut the middleman. Light-emitting diodes force electrons to jump across a tiny semiconductor gap, releasing pure photons without the sweaty byproduct. It is highly efficient, deeply cynical technology that slowly replaces the warmth of the world with sterile brightness.
One discovery leads to another.
