    Gravity flow melted ice,keep the ice coming-temp. is in their favor,2 crains could alternate2 reactors-cooler water that isnt salt,gd haz-mat rig a high temp funnel line to direct gavity flow just a suggestion(est.36-48 hrs to implementation ship-yard crn

    Amazing,after8 days-as for a lack of water sorce-how difficult for a crane to swing two modified water towers(plasma cut tops off get the ice there as this is staging crab boat bar.sea closer if pos. melt one hopper swivel melt another load ice w choppers

    liquid nitrogen would turn it into a large ice cube that could be picked up by helio and put into containment

    A.C OR Jim Walsh or Dr. Gupta.. i have a few questions on the cooling of the spent fuel rods and reactors, how come you cant use liquid nitrogen and water to cool it down to a point that it can be contained until they can figure out how to plug the leaks in the reacters and the spent fuel ponds? would nitrogen have a negative chemical reaction with plutonuim and uranuim. it seems to me heat is a big factor along with the containment of radiation.this could work with long pipeing to and from the reactors .liquid nitrogen will freeze anything

    What consideration has been given cabin air quality on trans-Pacific & Hawaiian air traffic now threatened by airborne radioactive particulates? Filtered cabin air on these flights certainly is at risk, I am sure you are aware in-flight air quality on even the most advanced aircraft is marginal at best. Please investigate the risks and report. Thanks, Kim

    Mr. Cooper,

    Has anyone suggested sending diesel-electric locomotives to the reactors to supply power?

    Most reactor sites have railroad tracks. The locomotives carry their own fuel and are therefore selfcontained.

    The only thing that I do not know is whether their electrical ratings(voltage, phase, etc) match what is needed at the site.

    Please pass this along, if you think it has merit.

    I have seen how really ineffective the use of water being dropped unto the reactors is, especially with the heavy winds and the fact that the choppers are flying at a 'safe zone above the reactors. I understand that it is snowing in parts of Japan. Can't the authorities now use snow instead of water. They'll certainly make a more direct hit and the reactors should cool faster.

    Why can't a hook and ladder fire truck poke a hose through a wall and put water into the areas where it is needed? Can this be done with military robots? Have the robots drag the water hoses into the plant.

    What about all the water they are pumping in? Is it picking up radioactivity and isn't it going out into the ocean – warm and possibly contimanated? Noone is mentioning the water?????

    we have drones that canfly over the site take pics come back be tested for radiation levels on planes when they land and photos analized

    Nuclear solution (maybe): Create an artficial tsunami using ballistics (dropped from planes) in the ocean near the plant. The resulting wave would flood the plant. Collateral damage would likely only occur in areas that have already been destroyed. Also, you're on an island – make sure you leave before pilots refuse to fly. Be careful, stay well, and thank you.

    Is it possible to pump liquid nitrogen into the reactors? Rapid cooling w/no explosions due to inert gas!

    Why are there not cameras on the power plant 24/7 for the people of Japan to see?

    Why isn't Japan using full sized unmanned remote control helicopters to pour water over the damaged reactors and spent fuel rod pools?
    The technology exists and it would allow the helicopters to hover at lower altitudes so they can deliver their paylods right on target.
    I'm sure the US Air Force posesses such helicopters that effectively operate just like unmanned spy drones.

    Why not use a helicopter to drop the end of a firehose on to the top of the building housing the spent fuel cooling pool and then pump sea water in from the ground? A grappling hook could be welded to the end of the hose so it would stay in place.

    Dr. Michio Kaku is brilliant! (Love his shows on Discovery Channel too) Excellent Idea to Solve The Nuclear Crisis in Japan. Entomb the Plants!

    It saves the Japanese Economy, and the rest of us as well.

    and I could leave tonight

    BUT if the distance is a problem then use a crane

    feed the and fasten the hose to the inside of the boom with 50 feet of hose hanging down

    track the crane closer to the target

    lower the boom into position

    lower the hose into the structure

    600 gallons per minute

    36,000 gallons per hour

    Why can't we go in with remote control planes, helicopters or some sort of remote control devise with video or pictures so we get a closer look. With todays technology why can we mechnically fastnen a bracket on top of the building with a nozzle facing down on the exposed fuel rods and just keep changing the hose connection back clear from truck to truck. Even a hydraulic telescoping pipe that could be extended into position.

    Looking beyond this disaster what is this I hear about small nuclear generating units using a technology that is safe and does not produce any radioactive waste? I have heard mention of this but no more than that. Is this just theory that has yet to be proven or what? Is it higher cost than current technology? Sounds like a good subject to look into.

    Has anyone discussed what would happen if the Japanese nuclear reactors are filled with cement, and what the risks and dangers would be if there were another earthquake and it cracks and/or become exposed again?

    The islands in Debai called "The World" are maintained by some sort of earth moving equipment that siphons sand from the sea floor and shoots it onto each island to keep their foundations from eroding. Is it possible that these machines could be commissioned by the Japanese government and situated on the ocean so as to siphon water instead of sand in the direction of the nuclear reactors?

  22. Shawn

    They should try fire boats. I am not for sure how far they are from the H2O, it looks close & is a unlimited supply. The fire boats can shoot several hundred feet and don't have to move. Just an idea!

    What's puzzling to me is the damage to the nuclear reactor structures in Japan, in contrast to the (seemingly lack of) damage to high-rise buildings. I mean these structures are, as I understand it, 5-6 stories.

    Any reason?

    Why can't Japan use solar panels on their battery packs?? Then use inverters for their AC Power!!!!

  25. Dale

    Don't know if anyone has brought this up but how about using an RC Helicopter with a Camera on it. The workers that are in the parking lot could use one or several to get a good look inside those reactor buildings. Then finally we could have a better idea of what's going on.

    The fire apparatus being used at Daiichi is totally inadequate for the task. There are concrete pumper trucks converted for firefighting that have booms that can reach 180' and are remote controlled. These could be borrowed from the US and delivered by C-17 to the Sendai airport, even in its sorry state.

  27. George

    Anderson, suggest to the firefighters to lay out enough hose to reach the top of the reactor building with a grappling hook at the end oof the hose. Have the helicopter lift the hook and drop it over the spent fuel pool and turn on the hose!

    Drop blocks of Ice instead of water. Also consider using lead-tin eutectic alloy (solder material) to drop on Spent Fuel Pool (baseball size balls or a suitable shape that will work). Lead is a shielding material and the low melting point of the alloy may allow sealing of leaks.

    Lots of co-workers from foreign countries were extremely quick to leave Japan. While I can understand how they are scared by the earthquake and radiation exposure, we Japanese have no choice but believe in Fukushima 100,working really hard to avoid further damage despite their own danger of being exposed to radiation.
