Some of us live in parts of the world where shark attacks are a real and terrifying danger. Whenever these people go to the beach, they have to be extra careful about their surroundings. Suspended nets are a good way to keep the sharks at bay, but they are not perfect. In addition, many times sharks or other maritime creatures get caught in these nets and die.
The Clever Buoy comes as a solution to this problem. It means to be an effective method of keeping people and sharks away from each other without harming either in the process. Used alongside other shark-sensing systems, this buoy can get rid forever of dangerous safety nets that harm maritime creatures.
This new invention is being developed by Australian tech firm Optus. The buoy is anchored to a box located on the seabed. This box emits sonar signals in the waters around it. Inside the buoy there is a processor that analyzes the reflections of those signals. In this way it looks for shark-sized objects that swim close-by. In other to decrease the chance of false alarms when other animals such as dolphins swim nearby, the Clever Buoy also takes note of the propelling method. It checks to see if the object approaching swims in a shark like manner.
The idea of the project is that a series of buoys could be arranged offshore, running parallel to the beach. Whenever one of them detects a shark, a message is sent t0 the local lifeguard’s smartphone. In turn, the person will sound the alarm and tell all swimmers to get out of the water until the sharks swims away.
This system is clearly more humane and less dangerous than nets. Moreover, the Clever Buoy is easier to install and maintain. What do you think about it?
