  1. Re:What about privacy? on Libel Suits OK Even If Libel Is Truthful · · Score: 1

    While I am not sure if this should be considered libel, I don't think the defense 'well it was true!' always triumphs as a legal defense. What about rights to privacy?

    Right to privacy is a different issue.

    The key point is that the trial court here has not considered any evidence yet. It made a purely legal ruling under Massachusetts law, and it was wrong because it failed to take into account the actual malice law.

    No, the key point is that the legal principle that truth is an absolute defense against a charge of libel is under attack in Massachusetts.

    Well, that's because the LEDs actually are missing (large) components of the spectrum! :-)

    Even when your eyes are tricked into believing the light is white (by equally stimuling the three kinds of color-sensitive cells), the light reflected off of objects isn't "correct". Imagine two green objects. One has true green pigment, the other has a mixture of yellow and blue pigment. Both look the same under incandescent light, because the light from a glowing filament emits a full spectrum .

    No!

    Incandescent light is extremely blue deficient. It's not at all "full spectrum".

    Colors look approximately right under incandescent illumination because your eyes are extremely good at color-adjusting the signal to the brain to compensate for the ambient light, and "most" things you tend to look at don't have sharp spectral bands. But in the case you describe, where a green color is synthesized from a blue and a yellow reflectance band, it will look very different under sunlight and incandescent light. (Look up "alexandrite", for example)

    The article sounds pretty damning-- if they move bad reviews down based on whether you advertise on the site (or even, apparently, actually write bad reviews if you don't advertise), that's extortion.

But there's no signal in radar, and even the carrier would be gone when they looked again to follow up, so to a SETI search, it would be tagged "noise"-- most likely a side-lobe of a transient terrestial source, possibly a satellite.

  18. Is it possible to model feedback loops? [Re:Wro... on Why Sustainable Power Is Unsustainable · · Score: 1

    Water vapor produces a positive feedback element-- the hotter it gets, the more water vapor in the atmosphere, and the higher the water-induced greenhouse effect.

    But, seriously, does that necessarily follow? One could also argue that the more water vapour in the air, the more clouds there are, which could conceivably increase the albedo.

    Of course. The original comment was about the greenhouse effect-- that is, infrared absorption-- of water vapor, so that was what I was talking about. As for other feedback effects, the post you quote continued: "But it's just one of many feedback effects, positive and negative."

    Since the top of clouds over 18,000 feet are almost all ice, and not water vapour, and ice has a very high reflectivity, it's at the very least arguable to say that the two effects might offset.

    Yep, that's the "negative feedback effect" mentioned.

    Note, however, that the negative feedback effece reduces temperature increase from the greenhouse effect, it doesn't eliminate it. (because if it eliminated it, of course, the feedback itself would be zero.)

    Of course, maybe they don't; I don't profess to have any data one way or the other. I'm just saying this is the type of reasoning that drives me nuts; it could be true, it could be false, but the AGW crowd takes one side, doesn't always provide data, or ignores data that refutes their position, and calls anyone who disagrees with them a nutter.

    Well, let's see, what would be the correct approach? Maybe, do a detailed physics-based computer model, and validate it with detailed measurements? That is what climate scientists do. That's pretty much their job description.

    ...I'm skeptical of AGW because I've read so many forecasts ("Tuvalu will be completely underwater in three years! Antarctica is melting!", etc.) when...

    Again, as I said previously, the characteristic failing on that side is not bad physics, but is a tendency toward hyping worst-case scenarios. Which I find almost equally annoying. There's a cherry-picking process here, though-- the press picks up and hypes the most extreme predictions, so if there's, say, ten thousand predictions, the single one that's wacky gets amplified, and the more moderate voices get ignored. Have you actually read the IPCC report? Not the popular media reports and the biased analyses from people with opinions, but the actual documents from the IPCC? If you're talking about predictions, this is the place to start, not whatever hype-of-the-week you got from scrolling around on the internet.

    It's amazing to me how many people want to throw rocks at the IPCC report and how few want to bother to actually read it. It's not the place to go for all the details (although it does have extensive bibliographies), but it's a good place to start, and written at a tutorial level.

    Since water vapor in the atmosphere is a dependent variable, not an independent variable (it is produced by evaporation of water, which depends on temperature), it's mostly a "so what" thing.

    Supratik Guha of IBM told the conference that sales of silicon solar cells are booming, with 2008 being the first year that the silicon wafers for solar cells outstripped those used for microelectronic devices.

    This is particularly worrysome from my perspective. This implies solar cell demand has a HUGE impact on the price of silicon. If demand for silicon solar cells has increased this much, then all these assumptions about silicon solar cells reaching parity with grid electricity within a few years in terms of dollars/watt may NEVER happen.

    Very recently the solar cell market has made an impact on silicon price.

    Not a problem in the long run-- the increased demand for silicon means that new silicon production capability has to come on line. This, however, means cheaper silicon in the long term, since newer plants can use more efficient technology, and also larger plants gather some economy of scale.

    It would be a problem in the short run, but (unfortunately) the economy has put a big drag on sales, and so there's probably much more capacity right now than demand.
