Millions of Jellyfish Invade Nuclear Reactors

oxide7 writes "A nuclear reactor in Japan was forced to shut down due to infiltration of enormous swarms of jellyfish near the power plant. A similar incident was also reported recently in Israel, when millions of jellyfish clogged the sea-water cooling system of a power plant."

    I have a theory that jellyfish are alien invaders, here to xenoform our planet. They love basically everything we do to the planet, from pollution to overfishing to global warming. This is just further evidence, but by shutting down nuclear reactors, the only current viable alternative to fossil fuel power plants, they ensure we use more coal and oil power plants, contributing to the environmental change they love.

      Many Jellyfish and Fish compete in their ecological niche. Because people the world over are over-fishing the sea, it leaves room for more jellyfish to snatch the food the fish would otherwise eat. Furthermore, Jellyfish are also nearly nutrition-less so people do not try to catch them. So, we have a collection of species of animal that have less predation vs. their main competitor and more food to eat, so they tend to thrive. Its not really a good idea for us to continue to ravage the sea life without regard to their continued survival. Coal and Oil plants really don't affect the Jellyfish as much.

      I was with you up to the last point.

      When carbon dioxide dissolves in this ocean, carbonic acid is formed. This leads to higher acidity, mainly near the surface, which has been proven to inhibit shell growth in marine animals and is suspected as a cause of reproductive disorders in some fish.
      ...
      The oceans currently absorb about a third of human-created CO2 emissions, roughly 22 million tons a day. Projections based on these numbers show that by the end of this century, continued emissions could reduce ocean pH by another 0.5 units. Shell-forming animals including corals, oysters, shrimp, lobster, many planktonic organisms, and even some fish species could be gravely affected.

      Most Asian cuisines have Jellyfish dishes. Some US fisheries even export Jellyfish to Asian countries.

      The problem is, preparation of Jellyfish for food is very time and labor intensive, due to the absurdly high water content that needs to be dealt with. Asians eat it, but not as a major dietary protein source like fish. So while it may support some small Jellyfisheries, there will never be huge fleets capable of making a dent in their populations.

    A friend of mine used to work as a deep diving welder. Things get pretty cold when you've got that much water between you and the sun, so they'd pump down warm water from the surface to let the divers stay under for as long as possible.

    Some of the divers discovered they could get even warmer by sticking the hoses into the neck of their wetsuit. After a few weeks of doing so, a number of jellyfish swam near the surface. You can probably guess what happened next -- one of them got sucked into the pump and shot through the hose, straight down the back of his wetsuit and settling right between his legs.

    It took a few days before he was able to walk after that, and probably a week more before he could do it comfortably. I guess he was lucky they weren't a more deadly variety, and that he had a buddy nearby to help him surface and remove his wetsuit.

      Cool story bro

      Your story would go over better if it were not so obviously fabricated.
      1) Deep waters welders: We almost always wear dry suits not wet suits.
      2) When we do wear wetsuits (short shallow dives in warm water) we want the water in our suit to remain constant because our body heat warms it up and it is trapped inside the suit providing insulation. You would be stupid to break your seal to pump in other water as you would loose body heat that way.

  6. US Navy vs Jellyfish by ikedasquid · · Score: 5, Interesting

    Jellyfish clogging marine heat exchangers is a common problem at sea, but is of particular concern for US Naval vessels using nuclear propulsion. Typically the only fix is to open the exchanger and manually clean the stuff out. Some ships have a capability to flush with either low pressure steam or reverse flush with firemain water (although the firemain is now also likely to contain jellyfish). How these multi-billion dollar machines are designed without a method for removing dead jellyfish is beyond my comprehension.

    Historically, we didn't have a population problem. China reflects the population growth of the entire world. Until about 1850, population growth was a stable thing, growing fractionally every century or so. After about 1850, we saw this exponential growth.

    The reason I picked China as the example, is that China has made a conscious effort to control population. One couple, one child. Negative population growth, which should put China comfortably within the land's capability to support their population within the next 100 years or so. (Sorry, no, I haven't researched projected population figures - I'm just guesstimating that 100 years from now, China's population will be (very roughly) about 1/4 what it is today.)

    Roughly half of the rest of the world still practices unrestrained population growth - all of Islam, all of the Catholic people, and much of the third world no matter their religion, politics, or anything else.

    I think it's past time that some of those people were brought up to date on the results of unrestricted procreation.

    the idea that there is insufficient land is bogus as long as we are paying farmers to not grow things. there is plenty of food, the problem is distribution and marketing. we throw away food every day from supermarkets and restaurants, and people go to jail if they try to dig in the trash for food to eat. there is no food shortage, there is a shortage of low-priced food, and that has nothing to do with the supply of land (except maybe as it relates to ethanol). it has to do with things like the Goldman Sachs Commodity Index Fund and other investment banks and hedge funds attempts to manipulate food markets for profit . . . something that is very old, a good 20th century example being the potato market and NYMEX.

    the problem with 'population control' is that someone has to decide what 'sort of people' are 'better' - nobody who thinks they know the answer to that should ever be in any position of power because it is amongst the basest, most primitive and violent impulses of the human species, to 'wipe out the other clan'.

      You're exactly right, that we produce enough food to feed everyone. Inadequate packaging and storage, as well as inadequate distribution channels, corrupt governments, and plain old poverty keeps a lot of it getting to where it needs to go. Much of it spoils before reaching market and much of it gets used as a political and social weapon.

      Just recently the UN FAO said we need to double our food output by 2050, when population is expected to reach 9 billion. Well, ignoring the fact that math doesn't make sense, it's missing the point. We can produce food for 6.5 billion right now. Production will need to increase to meet the demands of another 2.5 billion people, but the problem isn't production and never was. So long as there isn't enough refrigeration, pest-resistent procedures and packaging, and the roads and governments in place to distribute it adequately, production is irrelevant.

      You might be surprised to know that we don't throw away all human waste.

      We buy tandom truck loads (~10 cubic yards) of recycled waste from the waste treatment plant for $125 delivered, consisting of composted wood chips, leaves and sterilized human waste sludge. Many municipalities all over the US sell it. Cost varies from $10 to $15 a yard. This is only slightly cheaper than regular compost, at $15 to $20 a yard. We stack it up and let it "cook off" for another year before using in the garden, although it isn't actually required. This is deep, rich black compost that works perfectly to condition soil for lawns or gardens, and is far superior to standard "compost" you buy due to a higher manure content.

      I have also seen people buy just the sterilized effluent for spray fertilizing fields for animal feed. Very powerful stuff. Many waste treatment plants are expanding their ability to produce, as it is a profitable venture, which is reflecting in the fact that the price has gone up as demand has, at least here in North Carolina.

      So we don't actually waste our poop in America, like others believe. It is rapidly becoming a PROFITABLE product that makes the community money and reduces landfill usage. We still aren't doing this with all human waste, but we are well on our way as it is rapidly gaining acceptance. If my little town of 20k people are doing it, then any city can. I would be shocked if 90% of human waste isn't done this way within 10 or so years, as it makes money, grows great plants, and costs less than landfilling the material.
