Top binned Royal Blue Cree XP-E, XP-E2, XT-E, and Lumileds Rebel and "M" LEDs that I'm working with in the lab are pushing 55% conversion efficiency electrical to optical. Green OTOH is always about 1/3 of this, and red is 1/2 to 2/3. These are the efficiencies for current densities in the range of 0.35 to 1.0A/mm^2, which is the typical range of test to absolute maximum currents. Die temperatures at about 70-85 deg C.
Soraa LEDs might be reaching about 66-75% conversion efficiency (LED die only, not incl. phosphor). I will be sampling some soon to test this.
This is becoming a truly remarkable and world changing technology.
Part of the problem is low interest rates, set by the central economic planners at the Fed. 0% for short money is an emergency level, yet it's been 6 years of this shit. Interest rates should be HIGH, around 5-7% for intermediate term money would be good.
The.gov needs to just END all "aid" for paying for college. Then people would stop borrowing to pay for college. The price would collapse, and vast numbers of administrators and economically useless liberal arts ideology degree programs would vanish. There is no need to borrow to pay for college, unless the price has been artificially inflated. The same with home prices. High interest rates would reduce home prices to levels more in line with people's incomes.
There is something very wrong with the moral compass of a society that accepts the premise of luring people to commit crimes so they may be prosecuted while we cheer.
People who are on the verge of misdeeds, and where this is known to authorities, should be given warnings to change course lest they commit an act that warrants their removal from society.
Then it should be made a crime to entice people to cross the line.

You are engaging in deliberate intellectual dishonesty.
Libertarians do not reject laws. Someone selling food made from non food-grade oil could simply be charged with the crime of fraud. If actual medical harm was done, then they could also be charged with reckless endangerment, or in the worst case that someone died, manslaughter.
They would also be subject to civil lawsuit(s) for damages. In fact, such an act would warrant severe, most likely business liquidating damages just for the psychological stress and possibility of harm they subjected patrons to.
THAT is respect for private property rights. It starts FIRST with the individual's right to life, liberty, and property. Violate that, and there should be hell to pay.
You can be sure that 2000 pages of regulations aren't necessary when two or three simple lines in the law book are sufficient--provided that law gets enforced impartially no matter the wealth of the offender. One or two business getting liquidated and their owners going away for fraud charges will have the other busineses clamoring to establish a private standards consortium in a hurry, complete with self-motivated compliance and public posting of their independent lab assessments.
Well then, there's no problem caused by top-down control and institutionalization that can't be fixed by more top-down control and institutionalization, eh?
are the Rahm Emanuel's of the world.
I can't help feeling, ever since this started getting a lot of attention, that entry of Ebola into the USA was a fully planned consequence of our intentional complete inaction.
So you want the government to control the performance of your internet connection, and wireless phone? Because they are going to give you a free and open platform, plus yearly doubling bandwidth, right? After all, they have so much incentive to do so.
If you have been on this planet at any time during the past few years, you might have noticed that the first priority that any government has is making sure all your digital communications go through THEIR taps and get or stay unencrypted, so they can record your every move and search for any modicum of an excuse they can find to send a SWAT team over to your house to shoot your dog, blow your infant's face off with a flash grenade, haul you off to prison, and suffer no repercussions from their deadly mistakes.
And you are asking for more of it. Literally ASKING for more of this fucking totalitarian BS.
Most oil company people don't see it that way, or course. I'm not an oil co. employee, but I sympathize much more with their position than yours.
Most of the oil people I've encountered were extremely concerned about the well-being of the planet. But even more significant was the fact that they understood that civilization was riding on their backs, and so they were doing a job that must be done lest we descend into literal darkness.
Producing oil is extremely difficult. Most people simply have no idea. They may look at offshore oil platforms (only when they are undergoing a rare catastrophe, on the news), but not even remotely grasp just how expensive and difficult it is, and how many hard working people it takes to supply the consumers of 88Mbbl/day with the oil that they DEMAND.
Some oil folks with high calibre intellects, have gone off to try to help the process of developing viable alternatives to fossil fuels. Others are just doing their jobs. And the executives are just fulfilling their obligations to their shareholders. They don't make particularly high profit margins. The largest companies do make remarkably large profits on an absolute basis, which people like you think should simply be confiscated from them.
Maybe you and your ilk should just go ahead and try it. And then maybe those oil workers should just stop pumping the oil (not that they'd have much choice, as their company would go bankrupt shortly after becoming not profitable. Then we'll see if you can live in the world that results.
The fact of the matter is that WE buy the oil and WE burn it. No oil company forces us to do so. If you really care so much about the planet, stop buying and burning petroleum, or any utility supplied electricity or natural gas for that matter.
It is actually WE who should be made to pay higher taxes for burning the crap and putting the CO2 into the atmosphere. Or royalties that would get paid back to us creating a much higher REAL MARKET PRICE for oil while not significantly increasing our cost or allowing the money to get wasted by bureaucrats--a concept people might wake up to if only they had the ability to climb out of thier conditioning for even a second to envision some other approaches to price the commons that don't involve the currently failing model of government regulation/corruption and artificial, legislatively created "markets."
What is it with you people who take a situation where a market failure is obviously and explicitly the result of government regulation, and call it "de-regulating... gone too far?"
I've always known that the biggest obstacle to adopting sustainable energy sources would be government regulations protecting entrenched interests.
But we don't know if that is all there is to it. What does the brain do about it? Nothing? Does the brain just allow its equilibria to be swayed?
There is HUGE evidence that it does not just allow drugs of nearly all types to permanently alter its equilibria, but instead reacts to perturbations by adjusting various feedback effects so as to somewhat cancel the effects of the drug. This is the basis of the development of tolerance. The processes often involves *other* neurotransmitter pathways than the one targeted. The mechanisms can involve processes leading all the way down to the genes. There may even be higher order effects whereby gene expression is itself affected. Despite there being evidence of these phenomenon, there is little understanding.
Then what happens when the drug is removed? Are you worse off than you were before? Anyone who thinks they know is either ignorant or lying.
The truth is that it is extremely complicated.
We know only the tip of the iceberg.
Worse, we market dumbed down summaries about the known information about how they work, leading people to remain mired in overly simplistic (mis)understandings of how mood and mind are related to the physical brain.
In my country, that bastion of freedom known as the USA, they simply take your fucking money and your property whenever they want, just by saying you got it from drugs. It doesn't matter if it's illegal, or contrary to the 5th amendment, because that's just a stupid old piece of paper. And besides, they get to decide what words mean.
This is key. People have to understand that this is a pre-industrial economy. But worst than that, an ignorance society as well. They pose no threat to us, in terms of reasonably being able to attack or invade the continental USA.
That is of course, unless we are profoundly stupid. Basically, at this point, letting any non Us citizens from the countries infested with this religious extremist cancer enter the USA from an international flight, unless they have a damn good basis for coming here, is stupid.
Likewise for Ebola epidemic countries.
Next, we need to just abandon the f*cking middle east, Isreal included.
Humpty Dumpty is broken, and we are never, ever going to put it back together again. It's a FOREIGN CULTURE, nothing like our own.
It's very revealing, just how far "democracy" has progressed to a quasi-religion of its own, that we stupidly assume that if we just force those people to vote for their leaders, then suddenly they will become a liberal democracy, and everyone will be running around becoming social activists for liberal causes.
No No No No a million times no.
We have no idea what we are even doing in our own countries, which are on the brink of near catastrophic lurches downward into an abyss of totalitarianism and economic stagnation for reasons which are far too complex for any politically ideologically identified people to even begin to comprehend.
But if we keep spending our seed corn by attempting to police the world of people that are just not compatible with us, we stand a good chance of precipitating a similarly horrible outcome here, since there are plenty of people here who would be just as happy to implement their little version of hell. And I'm not referring to just one side of the political spectrum.
That is really the problem. How many people understand that if they were subject to certain societal conditions, that they too could act like ISIS, or the secret police of East Germany, or Kim Jong Un's inner cult, or yes, the Nazis? It's in ALL OF US to be like this. No one is enlightened. We just delude ourselves that we are, which is easy, because hardly any of us have ever experienced real stress of the kind that can crack you up, or the absolute need to conform in order to survive, lest you be tortured or have your head rolling down a hill.
There wasn't much implied by my comment. About all I can say is that the authorities are certainly stupid enough to try something like outlawing Bitcoin, but more likely they will create layer upon layer of new regulations that no one understands. The end result will be further ambiguity, which is perfect for the.gov because the objective these days seems to be to have so many laws with so many interpretations that you can basically bust anyone for anything if don't happen to like them.
I personally think there should be free and competing money systems, and governments should use other means for generating income, that don't require totalitarianism to enforce, as is the case with the current tax system(s).
I don't think it's as simple as wealth controlling the power structure. Certainly there are a lot of wealthy people with a lot of power, whether directly or behind the scenes, but there are also many wealthy who are just as much at risk of being victimized by the situation as you or I.
Making profits is evil! We should get free infinite bandwidth and healthcare. The government should make it that way. And by the way, don't mess with my personal liberties.
As long as most people are stupid enough to exist in such states of cognitive dissonance, then the situation is simply hopeless.
But you win too if you can actually grasp the implications of this truth. Not that there is any obvious practical solution. But if you get this then you can clearly understand why our current governing structures are such a threat to free society (free society != society without rules). And you will see how narrowly constrained is the thinking of political "progressives," "conservatives," and ironically, even libertarians.
If you have a science/engineering mindset, you may begin to realize that there is something seriously amiss with the situation:
We are trying to control society by using blunt force, when we haven't even the crudest working predictive model for human behavior, much less collective behavior.
It takes a great deal of arrogance, ignorance, and cognitive dissonance to persist at advocating the "state." It becomes virtually impossible if you get this. It's kind of like an "awakening." Once you see it, you can never unsee it.
Don't get confused by people who tell you that if you don't have a way to fix it, then there's no use pointing out how wrong the status quo is.
When something is inherently wrong, it is absolutely correct to cease doing it. Regardless of whether you know what to do instead. Why must you do anything at all?
No. Nearly every state has made it a crime to defend yourself against a police officer, even if that officer is threatening your life while violating your constitutionally guaranteed rights.

Then you'll get arrested, they will demand your Facebook password, then lock you up indefinitely when you can't produce it.
Or if they can't do that now, they will eventually. Basically where we're headed folks is, the government can do anything it wants to you, any time.
This simply follows from asking the government to do everything for you.
But by no means have we reached the global minimum!
There is something very wrong with the moral compass of a society that accepts the premise of luring people to commit crimes so they may be prosecuted while we cheer.
