Back in 2007 they did this at room temperature using Gallium Nitride and optical injection.

Perhaps this new electrical injection system would work there too.

This seems to be a duplicate, with better detail, of this Physorg story:-

The interesting question is how do they make their holes and electrons pair up into Bosons (And therefore obey BEC statistics) rather than act singly ( following Fermion-Dirac statistics). The coherence in energy levels possible in Bose Einstein Condensates is what enables their low level laser to function.
How is their Hole/Electron reservoir manufactured differently from the p (hole) and n (electron) 'reservoirs' present in any LED or laser diode.

Ignore the 1/5's I have a stalker who doesn't like accurate analysis (coupled with a bit of wild conjecture ;-)

Yeah. Otto is having a hissy fit and is busy working through all his sockpuppets.

It's funny if you think about it. Some sad, lonely guy sweating away at all that voting business and pretending he's multiple people - and thinking there's anyone that gives a damn (or doesn't notice that it's him on all these accounts).

He thinks that "if you can't win by reason - go by volume" means anything in science.

As if science were some kind of popularity contest.

only at a chilly 4 degrees Kelvin

We will totally ignore that 'degrees Kelvin' thing.

However, there's a big difference between a device that only works at 4 kelvin and consumer electronics. Mentioning consumer applications at this point is like selling commodity shares for resources located on one of the exoplanets we've spotted. In other words, she's jumping the gun a bit. Besides the fact that most people don't have liquid helium in the livingroom, there's health, safety, cost, product lifespan, etc to think about before you can actually use it in a dvd player.

Otto is only mildly annoying. I like his imagination, though a lot of his 'ideas' are borrowed from popular fiction. The problem is that he gets mad when anyone tries to tell him why his favorit fantasy novels aren't realistic. I heard one of our sanitation guys here yesterday talking about how scary "The Day After Tomorrow" is. I didn't say anything because someone who is that far out of touch doesn't really care.

Yes: Its tempting to retaliate on Otto's comments but the guy sometimes says something useful.
He just adds so much anger, and intention to provoke, into his comments that I leave most of them unmarked.

Yeah, he gets way excited over certain topics. He is so adamant that we are 'just around the corner' from so many of the sci-fi ideas from popular fiction. He has a good point when he points out that people in the 1930's would have called you crazy for suggesting that men would walk on the moon in their lifetime. What he doesn't see is that there were 10's of thousands of sci-fi ideas back then that never came to be, and most of the wildest things we have today were never imagined by any sci-fi writer. The bulk of future accomplishments are probably things nobody has imagined today. For example, fusion power may happen, but what if we stumble accross something even better before fusion becomes workable? Maybe fusion power will fade into nothing more than a historical curiosity, like steam powered cars.

if this research is correct looks like LENR is possible.

LENR (aka Cold Fusion) isn't impossible its just very, very, unlikely. But not as unlikely as my car quantum tunnelling into the garage.

All lasers are based on Einstein's principle of stimulated emission. Charged particles, such as electrons, exist in discontinuous energy levels like rungs on a ladder. An electron provided with enough energy can become excited and "jump" up to a higher energy level. Excited electrons can spontaneously fall down to an available lower energy level, shooting off the difference in energy as a bit of light called a photon.

Unfortunately nowadays we still do not know how 'the fall down electron' could create photon (the problem which Feynman could not answer his father), maybe understand the working mechanism could help the research ….
