One of the most powerful military navies in the world – the Chinese Navy appeared an enemy, which lacks the brain and even vertebrae. We are talking about flocks of giant jellyfish, which in large quantities fall into the cooling system of ship power plants, putting them out of action.
For this reason, the engineers of the Institute of Oceans and Fisheries (Dalian, Liaoying province) are developing a jellyfish shredder, which will become an insurmountable barrier to the path of marine invertebrates. The device is a network with cells covered with steel blades. Towed by a ship, she cuts into small pieces of a pack of jellyfish, clearing the path behind large ships .
The rapid growth of the jellyfish population is a problem not only for the Chinese Navy. Reaching sometimes the size of a large chair, they pose a danger to large industrial facilities and, above all, nuclear power plants, where seawater is used as a coolant. A huge number of jellyfish literally turn water into jelly, putting power plants out of order. So in the Philippines, millions of people were left without electricity as a result of the shutdown of a 1000 mW power plant due to the ingress of 50 tons of jellyfish into the cooling system.
Ironically, China has created this problem for itself, destroying annually up to 100 million sharks that feed on jellyfish. The explosive growth of their population is also largely promoted by overlimit fishing – China’s share in the world seafood market is 35%.
