Nowadays, the problem of Global Warming is on everybody's radar. We have the solution. All the DOE has to do is ask — and pony up many billions of dollars of taxpayer money, of course.

A new 200% efficient LED light has been fabricated in the laboratory. While this sounds like some "free energy" impossible dream, it does not violate the Second Law of Thermodynamics in any way. And, not only does this new LED produce more light than the electricity it uses to generate it, it cools the environment at the same time!
The LED behaves as a kind of optical heat pump that converts lattice vibrations into infrared photons, cooling its surroundings in the process. When an electron and a hole recombine, a visible photon is released and heat is also generated causing the lattice to vibrate more strongly. Under special circumstances, this generated heat will cause more photons to be released, removing that heat from the LED and producing more light. This is why the new LED is 200% efficient and cools itself in the process.
More information on this new 200% efficient LED can be found here.
