"[Brian] Korgel and chemical engineering professor Keith Johnston have found a method to make stable microscopic nanocrystals out of silicon that can emit light. And by toying with the size of the silicon nanostructures, they can change the color of the light that shines through. It can make essentially faster memory and generate less heat and radiate less power.""
Gosh that takes me back... or is it forward? That's the trouble with
time travel, you never can tell."
