Hows it work?


















----------------------------------------------








'A group of researchers in the US have unveiled an LED which emits more light energy than it consumes in electrical energy.





Researchers
from the Massachusetts Institute of Technology (MIT) unveiled the LED,
which has a conventional efficiency of greater than 200 per cent.





This
means that unlike traditional halogen lamps and newer LEDs, instead of
producing heat this LED will instead cool its surroundings.





Lead
researcher, Parthiban Santhanam of MIT, said: "The most counterintuitive
aspect of this result is that we don’t typically think of light as
being a form of heat. Usually we ignore the entropy and think of light
as work.”'

how the hell is that possible? every time you convert energy from one for to another there is a loss. how  hell are they producing a GAIN?

I'm always suspicious of two things when it comes to tech/science articles.

One: Reporters couldnt tell a transistor from chicken pot pie.
Two: MIT ... Anyone that has done DARPA challenges knows exactly why...

I’m calling BS on this one…

If someone told me that they had proof that bigfoot was flying around in an alien spaceship then I would be more likely to believe them than I am to believe this. That’s because both bigfoot and flying saucers might be real without violating some pretty basic rules of physics.

Now, I’ll admit I’m no physicist or quantum mechanic, I don’t even have a quark wrench. So maybe there is some bizarre loophole in the rules of physics that would allow something like this... but I seriously doubt it. So, if someone can explain how this might work I’ll be glad to listen, but it had better be a really good explanation.

Basically this diode converts thermal energy to light energy with an electric trigger.

the law of conservation of energy is still in effect

More light than energy? Connect it to a solar panel, aim the light at the panel, and then generate unlimited energy. This reminds me of an XKCD comic:

BS. Even if somehow some part of the system is getting colder, some part somewhere is getting hotter.  Net, they are still producing heat.

Sounds like a great alternative for tvs and projectors if they can pump enough energy into them.



Perfect for hydroponics for many plants. I'd just love to have the option.

Law of conservation of energy.....energy can neither be created nor destroyed. I'm no Einstein, but I know physics and chemistry. This goes against everything I learned in school. So I'm tagging this.

Light output is greater than the electrical input, because the additional energy comes from thermal absorption from the surrounding environment; so they calculate only the light output as 230% efficient compared to a normal LED that is than 100% efficient.

It operates at 30 pwatts.  That is 30 trillionths of a watt.  This may not be something that can ever have a practical application.

Buy one of these and 6 solar panels. Build box out of solar panels. Put led in the box and start selling electricity.

They are converting very small amounts of heat into very small amounts of light.
