    You haven't been reading slashdot recently, have you? Just last week we had an article about increasing efficiency of the photosynthetic process.

    The 5% efficiency number is due to chlorophyll breaking down and having to be rebuilt, constantly. If chlorophyll didn't break down, the rates of efficiency would experience a drastic increase.

    Use Apple as an example, expect the example to be used further in discussion. Common sense, Mr. AC, this isn't trolling, despite the morons without a clue modding me as such.

    Despite it working for thousands of other devices, Apple touts security as a major part of its platform thing, with tools to help you stop thieves from getting your information.

    This little thing makes every bit of that advertising moot, and once the device itself gets out into the wild (and it will,) Apple and other companies trying to play the security bullshit marketing are going to end up eating crow.

    "Our plants do not maximize energy absorption. Green light reflectivity is actually one of the worst choices that evolution could have made"

    No, that's a distant 5th or 6th place. One of the worst choices is that plants do not constantly utilize the light shining upon them. They use about 5% of what hits any given surface (with figures varying by leaf type,) and the light does not need to be steady, it can be pulsed. AS long as we have a sufficient photon flux density for the times the plant needs it, and it has a proper balance of wavelengths, it will pretty much do what it needs to do.

    This is why light movers work so well.

    "the energy in each photon does not matter so much, as long as it can excite an electron"

    This isn't entirely true. In fact, that energy level DOES matter as certain wavelengths will not stimulate as well as other wavelengths.

  7. Re:Spam on Worlds With Two Suns May Sport Black Plants · · Score: 1

    Well, chlorophyll is very LIKELY poor at absorbing green light due to the magnesium and nitrogen. Also, we have certain other chloroplast types that will work with at least a portion of the green light and give that energy to the chlorophyll, so chlorophyll really doesn''t NEED to be so good at absorbing green light.

    "In fact Green is just about the worst color (lets ignore white)"

    In fact green is a COMPONENT of white. White is a combination of ALL colors in the visible range.

    "And retinal exists and is much better than chlorophyll in terms of using the "right" part of the spectrum to get more energy from sunlight (though I think it's then less efficient at harnassing it)."

    What is this even supposed to mean? Do you mean to say you think that pigments from the retina would be better at absorbing and TRANSFERRING energy to a plant than chlorophyll? Just because it can absorb it doesn't mean it can transfer or convert the energy it receives directly to a plant, it may instead just be re-emitted back in the form of an emission line of lower-energy photon.

    "The green yellow wavelengths from our sun are the most powerful"

    Not really. Blue is more powerful. UV even stronger.

    "Earthy chlorophyll wants infra-red so the leaf bounces the green (and yellow) away."

    Carotene has some absorption in yellow and passes this on to chlorophyll for energy, so this statement is incorrect as well. Also, chlorophyll is more efficient at utilizing blue light. The times chlorophyll want IR is after the Pr reaction where exposure to deep red triggers it to switch to Pfr and prefer infra-red for the next photon, however there's a similar reaction between deep blue and UVA so IR and red might not even be required (I've grown cannabis under pure blue light with zero ill effect upon the plant from yield to quality, so at least some plants don't require it as long as you stimulate the phytochemical processes in sufficient quantity.)

  12. Plants would not be black on Worlds With Two Suns May Sport Black Plants · · Score: 1

    Not without some bizarre biological (and physical) changes.
    First, the plant would need multiple types of molecules with absorption peaks that would combine to cover the entire PAR range.
    Second, the plant would need a way of venting off all the heat so much energy absorption would generate. It would essentially have to become a heat sink.

    I deal with plants and light pretty much every waking minute. These little 'guesses' by these scientists are WAY, WAY off.

    That's exactly what I'm thinking. Sure the iPad may have some innovative uses where games like Bejeweled or other simple time-wasters are going to definitely dominate, and maybe for that market it will be successful. However, when it comes to serious gaming where you need BUTTONS to perform multiple actions at once, unless the iPad comes with a magical gaming attachment, it's not going to be very easy to work with, I suspect, and thus it will be utterly creamed in the serious/hardcore gamer market.
