The ocean is filled with eight million tons of rubbish—enough to fill five carrier bags for every foot of coastline on the planet. But a new invention could deal with this problem, one port at a time.
A pair of surfers from Perth, Australia, has invented a "floating bin" that automatically draws rubbish floating on the water into it like a vacuum (真空) cleaner. While the invention may do little to battle against five giant "garbage islands" that flow around the world's major ocean gyres (环流), it could stop waste from leaving harbours and marinas, for example. Peter Ceglinski and Andrew Turton said their device could spell the end of polluted seas.
The concept is simple: A bucket connects to a water pump, drawing in any floating trash inside a removable net bag. There is also an optional oil-water separator system inside the pump. It can remove oil from the seawater before spitting it back into the ocean — pollution-free — through the other side of the pump.
The water filtration (过滤) system is much like what you'd find in a fish tank, but it has the potential to clean up an entire ocean. The seabin can run 24/7, according to its website. And, amazingly, Peter and Andrew say they have never caught a fish or sea animal in their pumps in four years of testing.
The Seabin Project aims to improve on the traditional and sometimes expensive — harbor cleaning methods of having a person physically remove trash from the water or sending boats equipped with nets to collect it. While it's not as extensive as 21-year-old Boyan Slat's plan to clean the entire Pacific Ocean in 10 years, starting in 2020, the seabin's creators said their device is something that harbors can start using to clean our oceans now.
They're starting "close to the source of the problem in a controlled environment," Seabin's website states. "It's a big mission, but it can be done. In fact, we're doing it right now."
