    Considering we've got multiple decades of growing plants in everything from full gravity to microgravity, 1/6 gravity is a fucking simple task and has likely already been done.

    Done. It's more trivial than you think with LED.

    Hey, I have a novel idea. Why not power the LEDs via STRAIGHT DC ONCE IT'S AT THE BATTERY? LEDs *ARE* DC devices, after all.

    I feel so alone in this whole thread. Not a single one of you seems to have a clue. The downside of being a horticultural research director with a heavy focus on optoelectronic horticulture.

    I've grown EVERYTHING under LED. Cannabis grows and produces just fine.

    http://imgur.com/A55Ib,UzbUL,8JyQz,og8sk,t0ona - there's some proof.

    Lumens is fallacy and you should feel bad for using an architectural lighting standard in the place of a horticultural standard. Photon flux density is what matters, not lumens, which is stuck as GREEN LIGHT.

    LED experts will tell you lumens don't matter because lumens is BULLSHIT when it comes to plant cultivation.

    Quit reading words from idiots on cannabis forums.

    "That isn't to say that you can't grow with led just that 1000w HPS will grow stronger and healthier plants than 1000w LED,"

    That's an outright lie.

  6. Re:How ridiculous. on Nuclear Powered LEDs For Space Farming · · Score: 4, Informative

    A. You're rating LED efficiency by lumens - WRONG. Photon flux density. Remember, lumens are for humans.

    B. "Now LED's are at about 100 lumens per watt" - WRONG AGAIN. We have 5500K white LEDs with 150+ lumens per watt, and Cree has already broken 220+ lux/w - LAST YEAR.

    C. "So you need about 1,300 watts to light up one square meter to the same intensity as sunlight. Very roughly." Sure, but you're implying most of our food crops even need that sort of intensity - they don't.

    D. "Solar cells and inverters and wiring have an end-to-end efficiency of around 10%" Yea, if you use cheapo garbage. The stuff powering my research facility, end-to-end, pushes roughly 22%.

    E. "So we need about 13 meter-square panels at right-angles all the time to the Sun to get 13,000 watts during sunny days on the Moon." I see you totally ignore the fact that our moon has no atmosphere worth mentioning, so that photon flux density is actually much higher versus on earth, you also forget that the moon is closer to the sun then we are roughly half of the time, so again, the photon flux is even greater.

    F. "So we're back up to about 20 meter-square panels to light up one meter. To light up 50 square meters, one person's worth, that's ONE THOUSAND SQUARE METER STEERABLE PANELS." Except again, you're implying that plants need such intense light to grow. That's wrong. Totally wrong.

    G. "And oh, where are you going to get the water for 50 square meters of whatnot growing?" Plenty of hydrogen and oxygen on the moon, plus we've found water there. We can make fake snow by just expelling compressed hydrogen and oxygen in a shared jet nozzle (it's how we make snow during the summer on mountain ski resorts) so I bet making water from scratch components would not be that difficult. On top of that, we've got hydroponics systems that can drop water requirements as much as 99% for many crops.

    Your numbers fail to take into account how plants grow and just how much space is needed.

    And as an aside - I do this professionally. I'm going to have to say your words are sorely lacking in knowledge on the relevant subjects.

    "Having a static development target means x360 and ps3 games look better then their equiv gen pc cousins ever can/could."

    I am sorry, but you're full of shit. When the 360/PS3 came out, we already had GIGS of RAM in our machines, with far more advanced GPUs (The PS3, released in November 2006, ran a modified 7800GT, that same month saw the 8-series GeForce GPUs come out) more hard drive space, and more. The limitations of consoles forced developers to LOWER texture/model/level/detail quality and come up with rendering tricks to make games work with such limited hardware.

    Almost every single comparison between a console game and the equivalent PC version shows the PC version way ahead of the console in detail, effects, and more, even when the PC version is a port directly from the consoles. Why? MORE AND BETTER HARDWARE ON THE PC END.
