Startup plans to cool data centers by converting heat to light

Oh this again? Yeah, not efficient enough to beat out fans in non-vacuum based environments. Come back to me when there is a research paper outlining how doing so is better by any of our understandings of physics first, than some startup trying to raise.

This is cool, but it sounds very far from having a meaningfully helpful prototype, not to speak of a product moving towards production. Very interesting but I don’t think it’s happening soon
