What is with everybody stealing my great ideas before I have them? :-P For instance, yesterday I was thinking about lighting and it occurred to me that you ought to be able to take a laser (very efficient, see link) and pull the same kind of trick used for white LEDs to create a high-efficiency light-source. That is, send the output through phosphors; white LEDs are actually UV LEDs. Turns out, somebody else is already on it! One current problem is that UV lasers aren't as efficient as some others
