They turned heat into light using electricity. That may not be what people were thinking when reading the title/article, but I find this very cool, and I did not previously know it was possible.
- ars 15y agoIt's not quite as exciting as you might think. Heat into electricity is easy with a thermocouple. Electricity into light is easy with an LED. And heat into light happens automatically with black body radiation. It's not nothing though - it's pretty neat to use black body radiation to boost existing LED light output.
