Why the US Army electrifies this water

  • Publicado em 21 Ago 2022
  • The Chicago and Sanitary Ship Canal is the path that invasive carp would take to reach the Great Lakes. So to stop them, the US Army Corps of Engineers has installed an electric barrier. Although for obvious reasons, I didn't get to see it close up. [The interviewee is project manager Jeff Zuercher, whose name caption got missed out! Apologies, Jeff.]

    One interesting thing not mentioned: the local paramedics have been given a 'no rescue' order. If you foolishly go into or near the electrified water and become injured, no one will come save you. The risks to the rescue personnel are too high.

    That electric grid in the water is terrifying and I'm sure effective. I say terrifying because I had a friend years ago killed by being electrocuted in water. Faulty wiring on the boat dock, he dropped something in the water, went in to get it, horrible way to go. I wasn't there but I still get emotional thinking about that whole mess.

      @Greg Chambers so sad to disappoint you but electron do have a mass of 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton. It has a negative charge, I hope you've meant it, because being electrician and saying that nonsense scares as hell.

    • Lloyd Evans

      @Greg Chambers Electrons have negative charge, yes - but not negative mass. They do have some mass, just a very small amount - it takes 1840 electrons to equal the mass of a single neutron or proton. Hence why the atomic masses of elements are not whole numbers, because if measured to sufficient accuracy, the mass of the electrons in the atom make a small but detectable contribution.

      @Steven Strain Electrons are pushed and pulled by the steam turbine generators at 60 times a second (alternating current). Nuclear plants use extremely dangerous uranium to boil water to steam to turn the turbines. Generators and transformers work on electromagnetic fields. Water is the conductor here, but distilled water cannot transmit electricity. River and lake water do, but salt water is the best conductor as far as water goes.

    It's so sad the damage that invasive species can cause because they were introduced as a quick fix to a problem. I'm sure that most Aussies know about Cane toads, but they were introduced to deal with cane beetles. Unfortunately their toxins kill a lot of native animals and they now can be found all over eastern Australia. Humans can make such a huge impact with small decisions.

      European common carp didn't "enter" Australia, people took them there, same as they did in the USA as far back as the 1800s. Carp have been reared as food in Europe for centuries and misguided businessmen thought breeding and selling them was an easy way to make money. What they didn't take into account was that in warmer waters they spread like wildfire.

      @867diesel the bigger you are, the more voltage you get. It’s “voltage per inch” of surface area exposed to the electrified water. So a small fish is absorbing not much electricity, but a whole person is absorbing the same electricity as probably hundreds of tiny fish

    While this video is great- it doesn’t mention a huge issue, which is mis-identifying common carp (naturalized in the US) and Buffalo (similar to a carp, native to the US and extremely similar to carp) as the serious invasive species of silver carp or bighead carp. This has caused a witchhunt for these mostly harmless species, simply because they are carp as well. So many people will just kill any carp they come across because they think any carp is invasive, and its terrible when this occurs.
    In that sense, while the video is great for calling out this issue of asian carp in these waters, I think you should’ve said something specifying that there is this other issue as well, as I can guarantee that people will see this video and further be influenced to believe all carp are the issue and catch and kill them, which is just not correct.
    So please, on the chance that you catch a carp, please know that if its not an asian or bighead carp, there is absolutely 0 reason to kill it. In fact, its best to release them as they are incredibly fun to catch and don’t hurt the ecosystem at all!

    Carp problems?
    Years ago I watched two guys with a flat bottom John Boat. They built an air thruster fan which used a 4hp horizontal petrol engine. Tiller steering.
    They had crossbows with spools of heavy test braided line. They were arrow fishing for carp in two feet of water. The air thruster was wakeless. No startled carp. In coves they shut the engine off and moved by means of a pike. In two hours they speared many nasty carp. The lake had been a sewage impoundment. No fish were suitable for consumption. However white stripers were slowly becoming more prevalent. Summer time temps, carp stay in shallows. Proper game fish go deep.

    For anyone interested, a similar barrier has been proposed for the Suez canal in Egypt, to prevent fish from the Indian Ocean come to the Mediterranean. This migration is apparently facilitated by rising sea temperatures, and invasive species are already making a dent on the fish of the great Med. Most of them are inedible too (or even toxic to humans) so this is also a potential economic disaster for millions of people.

    Could just design a system with a small contained section that can fit the boats (like a lock) and the ability to pump all of the water and fish out to the carp side. Feels like pumping a bit of water out when a boat comes through might be cheaper than electrifying the water the whole time.

      @DarkCoreX Did you even watch the video? The canal is artificial, and poses a threat to ACTUAL ecosystems by potentially providing the means for invasive fish to reach the great lakes. Destroying the canal would prevent that with far greater certainty than this electrical solution, with the added benefit of preventing the loss of human life. The ONLY argument to keep the canal extant is its economic utility, but the potential to make money should never outweigh concerns of ecological damage and preventable loss of life.

      This is just my opinion. I think this electric program is stupid. Why not build a fence or net under water at the gateway to the canal that no fish could get through. It would have to come above the water a few feet, but look at the lower cost and higher safety issues!

    What about a lock system right at the end, where boats would go up an elevator, so to speak, right at the connection point.

    Why not make locks on either side? Once the boat is in, just zap the hell out of the water. Then even if the electrical system fails, you won't risk the fish getting through. And for the water, just have large pipes that are constantly electrified to kill anything that gets in.

    Hi Tom Scott, We have something similar but different in the Netherlands. There is a sluise or lock between a saltwater and freshwater that is supposed to stay separated. They originally pumped the salt water out of the bottom and pumped freshwater back in before opening the lock, but now they use bubble walls too keep the water separated. It looks really cool, and can be another interesting place video.
