I showed this article to my dad, it's very interesting. It apparently hits 100% then uses surrounding heat energy as well, and begins to cool off. Definitely WORTH THE READ

Sounds neat, but i highly doubt the actual diode is anywhere near a simple as that diode they have pictured in the article, i would much rather see what it actaully looks like

Very true, looks like a generic LED. It was also a challenge to say "LED from MIT" without sounding like a sing-a-long song haha

This is very interesting indeed - it would be amazing to have leds that consumed heat to supplement their power supply.

Nice find! well looks like they have their foot in the door, bring on the a big scale unit!

Interesting indeed - somewhat similar to heating something with a heat pump and achieving >100% yield if you compare output to electrical input only.
If something like this ever reaches practical size, you would have to provide a coldsink for continous operation... i'd be quite stunned if i had a flashlight or laser pointer that needed to be switched off because it froze instead of overheated some day

Now we only need a 100% efficiency l.e.d. driver.........................

Now we just need a way to combine several million of these into one device, we might could get a lumen or two out of it! :evil:
Seriously, I have a feeling like this is something that won't scale up too well, but neat discovery nonetheless :yh:

We could use our 445nm diodes as the heat source:evil:Interesting indeed - somewhat similar to heating something with a heat pump and achieving >100% yield if you compare output to electrical input only.
