Solar-Powered Vacuum Could Suck Up 24,000 Tons of Ocean Plastic Every Year

With more plastic than fish expected in our oceans by 2050, cleaning up this mess seems like an impossible task. But a team of inventors from Sussex, England have developed a novel solution. The SeaVax is a solar- and wind-powered ship that can suck up plastic waste.


The inventors at Bluebird Marine Systems LTD unveiled their proof of concept at the government-funded Innovate UK show in London in November. The inventors are entering prototype phase, the Express reported.

The ship purportedly works by funneling plastic waste as it moves forward. According to this mockup posted to the Innovate UK website, once built, the vessel will be around 144 feet long and fully autonomous. Deck-mounted solar panels and two wind turbines will feed power to electric pumps and filters that can suck up plastic solids and micro plastics. An onboard shredder rips and breaks up larger pieces of debris.

The builders calculated on their website that the finished robovac will be able to generate enough energy to treat an average of 89.9 million liters of seawater in a year, translating to 22,400,000 kilograms of plastic from a body of water that has high concentrations of surface solid plastic, such as river estuaries.

"Working in a fleet, these autonomous robotic boats could keep plastic buildup contained and significantly reduce the existing ocean gyres in around 5-10 years, cost effectively," the inventors said.

The captured plastic is temporarily stored in a cargo hold that can carry around 150 tons of weight until it can be off-loaded or recycled, the inventors said.

"With our system all sizes of rubbish, from huge fishing nets to deadly micro particles, can be swept or sucked up, ground down and stored in SeaVax's tanks," project director Chris Close explained to the Express.

The project has reportedly cost £138,000 (roughly $198,000) and a year to develop.

There are various ocean cleanup projects already underway, but Dr. Marcus Eriksen, research director at 5 Gyres Institute, explained to EcoWatch that many of the open ocean techno-fixes have died down in the last five years.

It's "mostly because the science of plastic pollution tells us plastics fragment quickly, are mostly small particles widely distributed across the globe and are highly toxic after time at sea—more akin to a smog of plastic rather than a consolidated patch," he said. "Recovery is much more challenging than we thought, and the ocean is rapidly beaching it and sinking the smallest particles."

Dr. Eriksen also pointed out that by-catch and the unintended killing of passively floating organisms that can't swim away is a big issue around any cleanup contraption.

Another issue, he said, is the "PR challenge of not letting post-consumer cleanup distract the attention of the public and policymakers from circular economy thinking, like upstream design innovations and policy intervention that prevent the problem in the first place."

For what it's worth, Bluebird Marine Systems said their finished SeaVax will feature automatic shutdown in case marine life is detected, as well as an SOS beacon to alert rescue workers of any marine life-threatening situations.

The company also said on their website, "We agree with most others, that we must begin to look closer to home, to try to prevent our rivers from feeding the oceans in the first place—and we should use less plastic for packaging."

Open-ocean clean up devices are better for capturing persistent plastic products like fishing gear that's designed to last years or decades, Dr. Eriksen noted.

"Catching that before it fragments into microplastic is worthy," he said. "The biggest advantage to these clean-up contraptions is deployment upstream. That's where the waste really is the worst. You'll get your biggest bang for your buck, and you will save our seas from the greatest source of contamination. The further upstream you go, the more success you will have."

According to the Express, Bluebird Marine Systems has already received interest from people in India trying to develop a clean-up solution for the polluted Ganges river. There was also interest from Nigeria and Australia who might want to use the device for oil cleanup.

The Past 5 Years Were the Arctic's Warmest on Record

The Arctic is still warming at twice the rate of anywhere else on Earth, and the region's air temperatures in the past five years between 2014-2018 have exceeded all previous records since 1900, according to a peer-reviewed report released by the U.S. National Oceanographic and Atmospheric Administration (NOAA) on Tuesday.

The agency's 13th annual Arctic Report Card also concluded that 2018 was second only to 2016 in terms of the region's overall warmth.

3 Key Dangers of Solar Geoengineering and Why Some Critics Urge a Global Ban

By Justin Mikulka

A Harvard research team recently announced plans to perform early tests to shoot sunlight-reflecting particles into the high atmosphere to slow or reverse global warming.

These research efforts, which could take shape as soon as the first half of 2019, fall under the banner of a geoengineering technology known as solar radiation management, which is sometimes called "sun dimming."

Report: Current Climate Policies Will Warm the World by 3.3˚C

This past October, a widely disseminated United Nations report warned that far-reaching and significant climate impacts will already occur at 1.5˚C of warming by 2100.

But in a study released Tuesday, researchers determined that the current climate polices of governments around the world will push Earth towards 3.3˚C of warming. That's more than two times the aspirational 1.5˚C target adopted by nearly 200 nations under the 2015 Paris agreement.

The Lesson From a Burning Paris: We Can’t Tax Our Way Out of the Climate Crisis

By Wenonah Hauter

The images from the streets of Paris over the past weeks are stark and poignant: thousands of angry protesters, largely representing the struggling French working class, resorting to mass civil unrest to express fear and frustration over a proposed new gas tax. For the moment, the protests have been successful. French President Emmanuel Macron backed off the new tax proposal, at least for six months. The popular uprising won, seemingly at the expense of the global fight against climate change and the future wellbeing of our planet.
