MIT is at it Again: Creates LED with 200% Energy Efficiency (Outputs More Energy than is Input) - Polidicks

[quote]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.[/quote] [url]http://www.lighting.co.uk/news/mit-creates-led-that-cools-its-surrounding-environment/8627537.article[/url] Fucking hell.

hook up to solar panel infinite energy

im sorry, but what?

[quote]This means that unlike traditional halogen lamps and newer LEDs, instead of producing heat this LED will instead cool its surroundings.[/quote] Turns out, the blue LED's in your computer actually do make it cooler!

how is that even

So essentially it just sucks the ambient heat energy out of the surrounding environment and uses it to produce light? Entirely within the laws of physics, then

Isn't this against the law of efficiency? well not law but you know what i mean.

"New power plant finishes construction: Reporters unable to take photos due to it literally being a giant lightbulb."

Right so it must take in heat energy and electricity, and convert it to light I guess.

Really stupid/sensational title. You don't get energy out of nowhere. Laws of thermodynamics.

I can't help but think that the writer of the article got something wrong here. If it produces 200% more energy than it consumes, that breaks the laws of thermodynamics. Like we're talking perpetual motion machine impossible here, unless there's some other mechanism at work. If it's like 200% more efficient than most modern LEDs that would make more sense.

It's not outputting more energy than it's getting input. It's just using a different source than the plug in the wall to make the light.

OP really means it makes more light energy than electricity taken in. He's forgetting it takes in heat also

Holy hell, one of the biggest problems with electricity is that everything always wants to give off heat and there are about no efficient ways to re-use that heat, it's basically lost. This is amazing.

This title isnt even sensationalist, its just fucking wrong

[QUOTE=DOG-GY;39580195]It's not outputting more energy than it's getting input. It's just using a different source than the plug in the wall to make the light.[/QUOTE] Explain more please, im wondering how this is working

I have a feeling this is false. This is defying the laws of physics.

[url]http://www.physicscentral.com/explore/action/led1.cfm[/url] things to consider: 1) its input and output are tiny (~10^-10 watts) 2) it outputs in the IR range 3) it works by using heat energy from its surroundings this thing's sort of like a tiny fridge which shoots heat rays. think about that for a bit

I may not be a smart man but, uh [QUOTE]instead of producing heat this LED will instead cool its surroundings.[/QUOTE] B-but thermo-- I don't even know anymore.

[QUOTE=areolop;39580248]Explain more please, im wondering how this is working[/QUOTE] It pumps in heat from the environment and uses it to create more light. [url]http://prl.aps.org/abstract/PRL/v108/i9/e097403[/url]

[QUOTE=areolop;39580248]Explain more please, im wondering how this is working[/QUOTE] if it's cooling the area around it, then it must be absorbing that heat energy; heat doesn't just vanish, it has to go somewhere in order for something to cool down. The heat energy held by the air around it must be getting absorbed by the bulb or some attached system and converted into light energy

So if you hook these to an Nvidia card you'll have a LED that outputs the brightness of a sun, yet cools the Nvidia card appropriately? Fucking wizardry if you ask me

The light is outputting more light than its [B] electrical[/B] consumption

[QUOTE=Eudoxia;39580271]I may not be a smart man but, uh B-but thermo-- I don't even know anymore.[/QUOTE] come on man, don't get taken in by this horseshit misrepresentation. you can imagine a tiny fridge, right? now imagine counting the heat it produces out the back as "output energy", and you have a fridge with >100% efficiency. it's that, happening on a tiny scale, in the form of an LED

[QUOTE=Maloof?;39580121]So essentially it just sucks the ambient heat energy out of the surrounding environment and uses it to produce light? Entirely within the laws of physics, then[/QUOTE] That's actually kind of awesome; all we need now is a device that sucks up environmental heat to convert into electricity, and we'd have a machine that could double as a refrigerator and a power generator. Sure it'd probably need electricity to start up, like jumpstarting a car engine, but if it's still within the laws of physics it could in theory keep itself running on the electricity and continue to cool down the surrounding area; almost like a Warlock's Wheel only it works with heat and needs an initial jumpstart to bring the cooling in motion. However, the Wintersmith Wheel would still need to have a failsafe that allows it to be turned off, otherwise things could go belly-up without smashing the damn thing to pieces in an effort to stop it.

It sucks heat from the air and turns that into light as well.
