Ultra-efficient LED puts out more power than is pumped in
- joering2 15y ago"it appears to draw in heat energy from its surroundings instead. When it gets more than 100 percent electrically-efficient, it begins to cool down, stealing energy from its environment to convert into more photons." Am I reading this correctly?? Did they actually find a way to create light AND cool down environment the same time? Could this be some sort of a breakthrough in cooling devices??
- Arelius 15y agoMy guess is that it doesn't scale. It seems to violate the second law of thermodymamics.
