The germans are not happy about their incandescent bulbs being taken away:

This is actually possible. I have a book on non-linear optics. Frequency doubling is possible with high efficiencies (>50%). Normally this uses dichroic filters, so I am not sure how this would work with broad range frequencies. A common green laser pointer is an example of this. The basic principle of frequency doubling is not really (very) complicated. In any optics system there will theoretically be some second harmonic generation, although normally this is negligable. However, by amplifying the desired second harmonic and suppressing the original frequency, conversion is possible. To preemptively answer your question, two photons do indeed condense into one, which is not that complicated to understand since the photons are already coupled with the transmitting medium. Indeed, transmittance is actually just absorbance over multiple dipoles (where the wavefuction has not collapsed) and synchronised emittance. (that is why light travels more slowly through glass) For practical frequency doubling devices, it is almost always a mutliple pass optical system. If such a lamp were possible, presumably just the filament unit would be replaceable, while the more expensive optics would be a permanent fixture. Now to go off on a random tangent... spontaneous frequency doubling in a vacuum is not possible because of photon spin conservation, but spontaneous frequency tripling is... (although so negligible it cannot be detected)

Something else to consider is hydrocarbons, which are relatively chemically inert, similar to fluorocarbons.

If Obama was pro-life he would be very convincing. That was an excellent speech. I wonder if he realises the dark irony of what he read.

What about candoluminescence ? Like the thorium mantle used in camping laterns? Could tungsten filaments coated with a thorium and cerium oxide coating to increase their efficiency? Could coating the tungsten filament with a thorium dioxide coating prevent evaportation of the tungsten? Since thorium dioxide is a ceramic, it is not vulnerable to evaporation at high temperatures close to its melting point. With the photonic crystal filaments, would it not be impossible to somehow fill the tungsten lattice structure with translucent thorium dioxide ceramic to prevent evaporation and degredation of the vulnerable fine structure? I found this, that some of you may find interesting: http://www.lamptech.co.uk/Spec%20Sheets/IN%20WC%20DuroTest%20120-65G30IRC-E26.htm

Quantum physics understands the mathematics that desribe the predicted behavior, they just do not know the underlying cause, if there even is a cause, or whether it is just an inherent law of nature.

Helium is the only noble gas that does not have 8 electrons in its outer shell. And hydrogen does form a metal-like state under extremely high pressure. An argument certainly can be made that hydrogen has chemistry in common with both halogens and alkali metals. But really, hydrogen is its own unique group. This is one of the problems when you try to classify different unique sets of properties into defined groups. The periodic table is like racism against chemical elements.

I am of the opinion that the medium through which photons travel is a type of electromagnetic energy itself, composed of long wavelength photons in a state of flux and equilibrium. This energy behaves as "virtual" energy because self-interference prevents it from permanently imparting energy. The carrier is referred to as "vacuum energy", and has a far higher energy density than matter. My view is that in the absence of a medium, a photon would travel infinitely fast, or from a different perspective variations in density of the vacuum energy would be like curved space. In the absence of vacuum energy, the entire universe would be much smaller.

No, actually a permanent magnet does give off real photons. They are extremely long wavelength, and it is dependant on the movement of the magnet. If you moved a bar magnet yesterday, and plan to move it back to its original position tomorrow, it is currently in the process of emitting real photons, at least theoretically. Normally these photons will almost entirely be "virtual", it is only when there is an actual interaction with the magnetic field that they will become "real". It may be difficult to conceptualise, but these photons are fundamentally no different than any other photons.

I had this idea for a new type of electric motor. (see diagrams in attachments) I have not actually built a working prototype. Would it work? Or specifically what I am asking is this: I know that the current flowing towards the magnet can result in a perpendicular force. Is it possible for current to flow away from the magnet (as indicated in the diagram) without inducing an equal and opposite perpendicular force? The new type of homopolar electric motor is similar in principle to the faraday motor. Unlike the faraday motor, however, this new design can easily be adapted to utilize multiple turns in the wire; in other words it can use coils of wire, rather than only a single wire. This motor has the advantage of running on simple direct current, without the need for any sort of commutators, either internal or external. In addition, the design does not require any conventional brushes. Pivotal electric contact points are still required however, but these have some advantages over brushes. Conventional electric motors cannot be designed to only use pivotal contact points without problems of the coil frequently getting locked up, caused by normal variation in the mechanical load. It should also be noted that even if the wire is held in place, with the magnet allowed the freedom to spin, there will not be any circular motion induced on the magnet. This seeming asymetry can be explained by the fact that the circular motion induced on the copper wire is relative to the external circuit (which is away from the magnetic field), not the magnet. Also note that the critical L-shaped section of wire must be on one of the polar sides of the magnet, and the wire must be diagonal to the magnetic axis. Simply having a toroidal coil which surrounds the magnet will not cause any induced circular motion in the coil, because the winds would be aligned with the magnetic axis. The copper wire must be rigid enough to maintain its shape. The only freedom of motion allowed to the L-shaped section should be mobility around the magnetic axis, while maintaining its relative distance and alignment with respect to the magnetic field. Unfortunately, this motor design cannot work in reverse as an electric generator. Obviously, the more practical application of this design is that it can allow the faraday motor to utilize multiple turns in a coil, an therfore gain the required efficiency to become practical for commercial operation. In the well known Faraday motor, one of the contact points must be around the radius of the magnet, otherwise a straight wire will be subject to opposing mechanical forces, as the wire tries to flip to be perpendicular to the magnetic axis. If the wire segment is constrained, only free to revolve around the magnetic axis, there would then be no induced motion, as the opposing mechanical forces in opposition are equal in magnitude, and the vectors (at any given instant) are parallel to eachother and the allowed mechanical motion. For the Faraday design to utilize a coil would require countless contact points, making such a potential design both impractically complex and unreliable in actual operation. The Faraday motor is only a demonstration of electromagnetic principles, with absolutely no practical application. Simply thinking only in terms of "magnetic poles" is not adequate to understand the operation of either this design or the Faraday motor demonstration.

These organic semiconductor polymer strips could eventually replace fluorescent lighting. They have a much better quality of light, and are comparable in efficiency to current LEDs. They contain multi-walled carbon nanotubes and operate best on 80 kHz frequency current. http://www.gizmag.com/fipel-alternative-fluorescent-lights/25287/ http://www.sciencedirect.com/science/article/pii/S1566119912004831

I was thinking about the idea of using molten tungsten as the incandescent source, contained within some translucent ceramic. Thorium dioxide is a translucent white ceramic with a melting point of 3390 C (3663 K). Tantalum nitride is a dark brown colored ceramic with which melts at approximately 3360 C. It is insoluble in water. Unfortunately nothing seems to quite match tungsten's 3422 C melting point. or perhaps someting like the Nernst lamp. If the filament was immersed in a molten ceramic, it would probably prevent evaporation of the filament so that it could me operated much closer to its melting point.

But there is not much point in switching if the evenings are cold most of the year. The CFLs can give off UV, which may be undesirable in many situations, and (most) CFLs give off an inferior quality of light. Again, the better quality of light, the more expensive it is. This misguided notion that everyone switching to CFLs will reduce energy consumption is based on a number of false assumptions. The big 3 light bulb manufacturers were the ones pushing this, and all the gulible environmentalists jumped on board without asking questions. There are quite a number of common situations where switching to CFL bulbs will result in more energy consumption, not less. An efficiency mandate was a terrible ill-thought out idea. But then again it was drafted to increase profits, not save the environment. The light bulb manufacturers essentially drafted the legislation. GE spent more money on political lobbying than they paid in taxes. They are trying to go after China and Mexico because that is where all of these less expensive incandescent bulbs are made.The real secret to the light bulb phaseout is government sanctioned monopolies. Guess who holds the patents on LED technology? Yes, there are a number of very small companies (with limited research budgets) but none of them will be able to ramp up production anywhere near what the big 3 will.GE, Phillips, and Osram Sylvania stand to make enormous profits once they have succeeded in getting the government to take consumer's other options off the table.

"The greatest destroyer of peace is abortion because if a mother can kill her own child, what is left for me to kill you and you to kill me? There is nothing between." — Mother Teresa "Abortion and racism are both symptoms of a fundamental human error. The error is thinking that when someone stands in the way of our wants, we can justify getting that person out of our lives. Abortion and racism stem from the same poisonous root, selfishness." — Alveda King

another article, confirming that ambient heat is transformed into light, resulting in a cooling effect: http://physicsworld.com/cws/article/news/2012/mar/08/led-converts-heat-into-light In principle, it should be possible to use room temperature heat as a free energy source. Only technical barriers exist.

When it comes down to it, it is just not possible to grant women the right to an abortion without simultaneously taking away the rights of the fetus. Just like rights were taken away from business owners and apartment owners in order to give other people "civil rights". One has to question whether it is really a right when, in order for it to be granted, someone else has to be denied their rights. As far as I am concerned, slavery, the "civil rights" movement, and abortion are all the same. In each of these three instances, one party claims a right at the expense of another. Most women who are seeking abortions for their convenience never even bothered to make sure the man was wearing a condom. While 72% of women who were getting abortions had not used condoms with their sexual partners, 46% of the women had not bothered to use any form of contraception! More than 86% of abortions are done for the woman's convenience – in other words they didn’t want the child or felt they couldn't afford a baby. Less than 1% of abortions are performed because of rape or incest. ( source: http://www.guttmacher.org/pubs/journals/3429402.html ) Let me ask this question: Who should be the one penalised for the poor choices made by the mother?

Under slavery the Negro was brutalised and denied personhood. Now it's the fetus. The abortion-lobby seeks to make the fetus the woman's slave. Abortion is the Liberal version of racism— but so much worse!! I don't believe in restricting free speech. But if we do have hate speech laws, I think there should be hate speech laws protecting the fetus.

For those of you who do not already know about it, "The Silent Scream" was a classic pro-life video where a medical doctor explains in detail the procedures used in abortion. By today's standards it is a really slow and boring film (nearly a half hour long), but it was well made, and is still often referred to amongst pro-life activists. Abortion is a silent injustice. What is the true cost of a woman being "liberated" ? Sometimes I wonder just how many little human fetuses have to be sacrificed on the altar of women's rights. So sit back and enjoy the videos comments welcome. Perhaps these old videos will stimulate some good debate.

I support small island nations. I think there should be both a radical left wing and a radical right wing nation, so we can see what the actual effects of both ideological extremes are and compare them.

You can "grow" the economy as much as you want, but the simple fact remains that if the population grows faster than the economy, living standards will decline.

Isn't that what supporters of abortion are all about when they claim they are "pro-choice" ? It's called sterilisation, and should be used on women who repeatedly get abortions over and over again. Let's remember that even though we may never agree about what a woman's rights actually are, a human being's right to live is indisputable.

So what? If the woman wants to get an abortion, a vacuum hose still has to be shoved up her vagina. I don't see the problem. If a woman is so insistent on killing her unborn child, the least she should be obligated to do is face a picture of her fetus. If she does not even know what her fetus looks like, how can she really make an informed decission in this life-or-death matter?

This would be more than offset by a large labour supply desperate for employment, willing to work for low wages, which would undercut the wages of other construction workers. This is exactly what has happened in the southwestern United States. Besides, even if immigration did temporarily increase construction wages, it would be a one-time fix. Not really a sustainable way to add to the economy. The immigrants might contribute cheap labor to the economy initially, but eventually they have children and someone has to pay the costs of educating them, medical treatment, and dealing with the increase in crime from juvenille gang-bangers.
