This underwater robot cleans ships to cut emissions and protect marine ecosystems
- The build-up of marine plants and animals on ship hulls is an age-old problem.
- This ‘biofouling’ can increase fuel consumption by up to 40% and boost emissions.
- It can also transport species to new environments where they cause havoc in the local ecosystem.
- But now a robot has been invented that cleans ship hulls every time they anchor.
- Its makers say it will bring huge environmental benefits.
