Brilliant!

"The potential of light emitting diodes - tiny specks of semiconductor material - to replace Edison's energy-wasting incandescent lightbulb had been recognized since their invention back in the early 1960s. LEDs give off no heat, use little energy, and last almost forever. But progress was thwarted: despite decades of effort, nobody could make an LED that would emit bright blue light, the pivotal component in order to make useful white light LEDs. Then, in 1993, a previously unknown researcher named Shuji Nakamura took the world by surprise. He made the key invention from which has grown the multibillion-dollar industry of solid-state lighting. Bob Johnstone, veteran technology writer and the first Western journalist to meet and interview Nakamura, traces the inventor's epic story, how he invented his LED, and how his lights are changing our world."--BOOK JACKET.
