Cool Lasers

I’ve been reading a lot of science articles in the mornings as anyone who follows me on Twitter @nealasher or Facebook will be aware, but this one I have to put here.
As an SF writer you’re always in danger of being tripped up by the science geek who will point out your errors. Back in The Line of Polity(I think) I used ‘laser cooling’ for a space ship and someone – in a review I believe – dismissed this as a ridiculous idea.

In micro electronics heat often causes problems and engineers have to put a lot of technical effort into cooling, for example micro chips, to dissipate heat that is generated during operation. Austrian physicists have now suggested a concept for a laser that could be powered by heat. This idea may open a completely new way for cooling microchips.
