    Got news for ya.

    Most gaffers don't have a certification or license.

    I've had to repair three electrical systems out in Studio City.

    Not fun when you're working with 100 amp breakers (for those shitty incan lights) and the shit is all wired wrong or even half-backwards.

    Thank goodness AC is more forgiving than DC when it comes to wrong wiring order.

    That's not a good idea. The further up the chain, the slower the GFCI cutoff response time (even miniscule as it ay be.) That's why it's built directly into the outlet.

    You're working with the wrong people, for one, for load balancing.

    They're called ELECTRICIANS - something your sound engies, gaffers, and A/V techs very likely don't hold a certification for, let alone completed their journeyman's studies and time.

    GFCI does okay until the entire outlet is soaked. Then it's useless as fuck for protection.

    I can see these mounted on a couch or table getting fully-soaked no problem.

  8. Sounds like it's time for multiple micro-centers on Data Center Managers Weary of Whittling Cooling Costs · · Score: 1

    The concept is simple. We've got car AC units that are 400% efficient, meaning for every one watt of power consumed, 4 watts of heat gets removed from the system it is cooling, within a certain size (the size of the interior of a Ford Explorer, for example.)

    Then you make these into micro centers - insulated rooms, fully-sealed, holding no more than maybe 3 or 4 racks of servers. Have one or two of these cooling that room.
    Hey, suddenly, you're spending $1 in electricity to cool off $4 of used power (and if you have really efficient computers in those racks, probably LESS!)

    What's that PUE at that rate?

    Given that you're stating that the rising heat column would draw cooler air in across the plants, we can pretty much rule out heat, assuming your statement is true.

    If the caps are venting, they're not working and neither is the device.

    There are many other studies out there on this very thing, and I've done similar tests in a much tighter-controlled facility than what these kids had access to.

    Our germination rates in our wifi-enabled area are roughly half that of the germination area on the other side of the facility (and perfectly protected from outside radiation due to the building being one giant cluster of faraday cages.)

    I'll do you one better. I've already done this experiment with far better controls and computer-controlled everything in my research facility. Ive done it with cress, lettuces of various types, and fruiting plants such as tomatoes and peppers. The results are the same. This same setup is also how I test my LED lighting.

    Heat from the router and laptops is very unlikely to have been a cause. The rooms were computer-controlled for atmospherics, and the pictures clearly show the dead zone around the entire setup, not just around the areas where heat would be likely to vent and collect.

    To add, cress has quite a varied range of germination temperatures.

    You go right ahead.

    Any field I've lived near, or creek, with high-voltage power lines, that area is a DEAD ZONE directly underneath, unless there are plants already-established.

    And many of those areas don't even need maintenance like grass-mowing, since all that EM hinders growth.

    That's in Texas (Plano, Dallas, Port Aransas,) Tennessee (Memphis,) California (Redlands and Riverside,) and South Carolina (Dataw/St. Helena Island, Hilton Head Island, Beaufort.) I'm pretty sure you can find similar results.

    Outgassing? My god, people still think this is an issue?

    I run a HUGE facility loaded with PVC, HDPE, ABS, and other plastic channels.

    Outgassing is bullshit until you get into the solvents and adhesives used to join the system together.

    Most routers are screwed together, not glued together, and are almost always made from one of those above-mentioned plastic types.

    If there's an outgassing issue, someone's failing at proper ventilation or using the entirely wrong adhesives/molecular-bonding solvents.

    Uh, I use heated trays for seedlings all the time. Cress has a fairly WIDE range of germination temperatures.

    I think you need to go take some horticulture classes, or get a job doing horticulture, before you go on speaking about something you're totally wrong about.

    The seeds would have to have been right on top of the router for that kind of heat to affect them.

    The control is a regulated room without the routers, providing a known and many-times-over tested baseline.

    The variable is the wireless radiation, in a different room with the same controls, and that being the only variable.

    Heat is nowhere near enough to affect germination of cress. Trust me, that shit can germinate in a fairly wide temperature range.

    Sounds like you failed identifying variables. A control room will not have routers because the control is an area with known tested parameters. The room with the routers is the variable room. They used two routers to provide adequate irradiation levels in the room, as the variable.

    "Or just as likely, they just faked the data. "

    As someone that has performed similar radiation experiments as part of my research into zero-light horticulture, faking this is very doubtful, as I've encountered the same issues. Germination rates in the area of our facility with wireless access are roughly half of that on the other side of the shed that is totally free of radiation in that frequency range thanks to the natural faraday cage (the entire structure is grounded, metal walls and supports, etc.) that the facility provides. You can't even use your cell phone two feet inside the door.
