Did You guys hear about the new MIT LED???






I would think the guys at MIT know the laws of thermodynamics. Energy efficiency of 200% sounds so fake.
 
Before making such a blatant comment, perhaps you should read the article first, and perhaps even do a little research into using light as work and not heat.
 
No disrespect Blord. I've learned much about the hobby through your posts and comments and plan on calling upon you for my next build. I need a copper heat sink for a WF-502B.

I'll have to side with BLord on this one. 200% efficiency smells of perpetual motion. Getting more out of something than you put into it seems dubious, at best.

With that said, just because something uses electrons to produce work, or emit energy, doesn't mean it must be exothermic (produces heat).

There are many things in nature and science alike that are endothermic. My ex-wife, for example. :crackup:

I thinks its plausible, it draws heat out of the atmosphere, converts to electricity and used to power the LED, much the same as a TEC in a LPM.
 
haha, good stuff. @pschlosser
And who posted this!:

"lolwut no f**kinway?
This article is over a year old and so Jukka Tulkki spoke in 2012 not in 2013 you n00b."

I know someone here did, common guys, fess up...:D

"200% efficiency" is just a sensationalist title. It's not really 200% efficient, as it's taking power from electricity and heat. I would be interested in knowing how much power from heat it's using.

They guys at MIT aren't responsible for the poor journalism, but yeah the 200% efficiency is very fake.
 
It's 200% efficient without looking at the power it takes from the surrounding air...

It's technically wrong but technically correct, it just depends on how you view it.

But anyway, it's definitely an interesting device! But, it does make me wonder what use it could possibly have since the amount of light it produces is so small...
 
I don't think this device's usability as a product isn't necessarily important here, so much as it's impact on the future of the industry as a whole. Now that it's been done, engineers can make it practical.
 
So it and the driver have a built in tec that feed heat directly as electricity back into the diode. I guess this new diode could be 200% more efficient than what we have now... They state using it in freezing applications though... Would be a good future heat displacement. You would only have to direct light exhaust instead of heat...
