Italian designers create jellyfish-inspired device to clean up rivers

The Jbin is an electromechanical system designed for trash collection in water bodies. It consists of several components including a communication cap, paddles, and an anchor. The paddles rotate due to water flow, creating a vortex that traps trash. Polluted water is purified by bacteria in a filter. LED lights on top indicate when the bin is full or needs maintenance. The device can rise to the surface for cleaning. Additionally, Jbin emits ultrasonic sounds to keep fish away.

What is the primary function of the paddles in the Jbin system?

• To provide structural support

• To emit ultrasonic sounds

• To rotate and activate a helix

• To collect trash directly

How does the Jbin system purify polluted water?

• By boiling the water

• With bacteria inside a filter

• Through a mechanical sieve

• By using a chemical filter

What do the LED lights on the Jbin indicate?

• The speed of water flow

• The bin's fullness or need for part replacement

• The water temperature

• The battery level

What happens when air is pumped into the Jbin device?

• It starts emitting ultrasonic sounds

• It releases trapped trash

• It rises to the surface for cleanup

• It sinks to the bottom

What is the purpose of the ultrasonic sounds emitted by the Jbin's tripod?

• To attract fish

• To deter fish from approaching

• To signal the bin is full

• To enhance water flow
