    Can 225vac from Solar flow back to grid?

    This might answer most of your questions. http://www.wholesalesolar.com/pdf.folder/Download%20folder/gridtie_manual.pdf

    Can 225vac from Solar flow back to grid?

    Some meters are one way only. Most I have run across are 2 way (rotary) your 125VAC is half the leg of a 220v line.. it can still backfeed that single phase back into the grid in case of a power outage. automatic shutoff or "islanding" islanding is where the inverter passes through the...

    Can 225vac from Solar flow back to grid?

    Depending on how you have it wired, yes. the transformers work in both directions, and chances are the 220v line feeding your house feeds several others as well at a common connection point. if you have your inverters directly tied to the incomming panel, you really need to install...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    both quince and the packbot can open doors. there must be some situation that makes it not ideal for them to do this to have a human go in, open the door then send the robot in?

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    From what I recall reading, the Quince robots can operate in up to 2Sv worth of radiation reliably, I don't think the 0.2Sv measurement could have caused any problems. I will say I question their choice of the camera lens, it makes for some quite distorted images, maybe it has something to do...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    that 4 Sv/h source is really making the camera struggle.. I wonder what it looked like when they got closer? snow?

    Japan Earthquake: Political Aspects

    I admit that I am a little miffed by the quality and placement of the camera, but you have to remember a few things. 1.) They didn't have to provide anything. 2.) It is eating up (i'm sure) still limited communication channels. 3.) I think they have bigger problems. This is the type of...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    I still hold the view that using IR/thermal imagery from a closer distance could give them a better picture of where the core debris is located and they could possibly modify the cooling plan based on it's location. maybe an on site set of images from different angles could give enough...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    I would have to agree that it seems quite possible. now most of the site is shrouded in a fog, but it was definately coming from just the buildings to begin with, maybe the temperature change brought the dew point down enough, water evaporated etc. also, am I the only one that notices the...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    in unit 4? according to tepco there are no fuel rods in the reactor since it was all offloaded. edit: are they using one of the first ever webcams made with a horribly small picture and huge compression a like 9FPS. if they wanted people to guess and debate over minor things due to low...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    one thing nagging me about all that is wondering if the core of #4 was fully unloaded.. or if they were a little behind and just said oh yeah.. we did it. expecting to have it completed shortly?

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    Personally I would be driving through whatever I needed to to get to that school.. lawns other cars etc. and I'm pretty sure most parents would be the same way. guess it makes me feel a little better I live almost 40mi from the nearest N-plant. edit: I also noticed the local plants are no...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    seems to be the way things go, and because of it we miss out on a lot of great advances. I'm not saying it scales, I don't even think they know as they don't have any way to test it full scale, but if he's been developing similar things to clean up industrial pollution I would say he has a...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    All this talk of AREVA and their treatment plant.. whatever happened to this guy? http://blogs.wsj.com/japanrealtime/2011/04/21/chemist-i-can-clean-fukushima-water-faster/ They are working a close (5 day) deadline to overflowing... maybe they should give it a shot? I'm sure areva won't lend...
