The Manta is a hybrid catamaran that will collect floating plastic

Recently unveiled by SeaCleaners, the Manta hybrid catamaran is designed to combat the oceans’ plastic pollution in a brand new way. Using a biomimetic design, a hybrid propulsion system and a power supply from renewable energy sources, the high-tech boat will not only collect ocean waste but process it as well. Poised for launch in 2024, the Manta will operate autonomously 75% of the time without the use of fossil fuels, and it will have the ability to extract between 5,000 and 10,000 tons of floating plastic each year.

Its design allows the Manta to extract microplastics from 10 mm upward and up to 1 meter deep. Depending on the density and closeness of the layers of waste, the catamaran can collect between 1 to 3 tons of waste each hour. Even more impressive, its hybrid abilities means that this catamaran can operate for up to 24 hours a day, seven days a week.

Each boat is equipped with multiple collection systems, including a set of waste-collecting conveyor belts to bring the plastic from the ocean to the boat, three floatable systems to pick up surface waste, two smaller multipurpose collection rafts for shallower and narrower parts of the ocean that the larger catamaran can’t access, and two lateral cranes to pull larger pieces of debris from the water.

According to the designers, led by the company’s founder Yvan Bourgnon, the first mission of the Manta will take place in Southeast Asia. After that, the Manta will operate in Africa and South America but will also intervene in temporarily polluted areas following climatic or natural disasters.

The project is three years in the making and will mark the world’s only work boat capable of managing 100% of the plastic waste it collects. An onboard factory will help sort and treat the collected waste, while an energy conversion unit will convert the plastic into energy with a minimal environmental footprint. A combination of wind turbines, hydro generators and photovoltaic solar panels will produce renewable energy onboard.

To operate the sorting facilities, the Manta will accommodate 22 crew members and 12 passengers, including several scientists and researchers. After three weeks at sea, the plan is to direct the boat toward coastal ports in the area to raise awareness, educate and welcome the public onboard for activities or events regarding plastic pollution. As a result, the Manta will provide solutions to global plastic pollution and also act as an ambassador for the restoration of marine ecosystems and innovative plastic-collecting technology.

New riverside development in China will be an urban renewal

Architects VenhoevenCS have won a major riverside redevelopment in Shenzhen, China . They hope to protect large areas of land from flooding while also creating a vibrant new urban identity for the Bao’an district. The Pailao River Blueway Project constitutes a new biodiverse landscape along the central Pailoa River, an area under rapid urban development where rainfall intensity is increasing. Architects are using this project to design with the water instead of against it. It includes elements such as ponds, green roofs, urban farming plots, wetlands and soft banks, contributing to a natural sponge effect to absorb excess water from the river . Related: 100-year-old railway yard turned into a green space VenhoevenCS also has their sights set on integrating urban regeneration in the area.

Say hello to the new Toyota electric vehicle, the bZ4X

Toyota is trying to win the electric vehicle game with a stylish new SUV loaded with techy features. The all-electric bZ4X will be rolling onto the lots of U.S. auto dealers this spring. If the name doesn’t immediately strike you as catchy, it might help to understand that “bZ” stands for “beyond zero.” The bZ4X is the first of seven in Toyota’s new line of bZ vehicles. That’s seven out of 15 BEVs, to throw another acronym at you. BEVs are battery electric vehicles, as opposed to HEVs (hybrid electric vehicles) or PHEVs (plug-in hybrid electric vehicles). Related: Consider these factors before buying an electric vehicle All these Vs will help speed Toyota toward its goal of carbon neutrality by 2050. Already, Toyota has more than 20 million models on the world’s roads. The company has pledged to invest another $70+ billion in EVs over the next nine years. So, back to the bZ4X. According to Toyota, the new “BEV-dedicated platform, a first for Toyota, was developed wi...

NASA to test the world's first electric airplane

NASA has shared details of its new all-electric plane that is set to take off to the sky this fall. The plane is designed to run fully on electric batteries , departing from the tradition of fuel-powered planes. If all goes well, this will be the first step toward achieving a cleaner, cheaper, and quieter future for aviation. Known as the X-57, the plane is lightweight compared to traditional planes . Its weight helps it use less power over the same distance compared to its equal fuel-powered planes. Further, the plane produces less noise as compared to fuel-powered options. According to NASA, the plane is currently being prepared for initial tests, which will be conducted in the desert east of Los Angeles.

Biomimicry house hints at a solution to the climate crisis

Houses separate us from nature. At least, that’s the idea we’ve had until now. Architecture that uses biomimicry , permaculture and related practices to keep nature in our building spaces offers a green alternative. B+H Architects Director of Biomimicry Jamie Miller is an advocate of sustainable building practices like biomimicry to help with the climate crisis. Biomimicry creates an architectural option that keeps us connected to nature, without removing the biodiversity from the spaces where we live and work. Now the B+H Architects’ newest residential project shows us how a home can blend right into nature itself.

This DIY algae kit is an easy science experiment for kids

BioBombola is a DIY algae kit specially designed to teach kids how to grow their own domestic garden of spirulina – a sustainable source of plant-based proteins. The project is the brainchild of ecoLogicStudio’s Claudia Pasquero and Marco Poletto, who wanted to create a fun and educational way to keep their children occupied during the shutdown in London. In addition to cultivating the nutritious blue-green algae, the kit also helps to absorb the same amount of carbon dioxide as two young trees and provides the home with the same amount of oxygen as seven common indoor plants. Perhaps best of all, BioBombola allows children and adults alike to interact with nature from the comfort of their own homes. Related: Eos Bioreactor uses AI and algae to combat climate change The two researchers got the idea after creating an algae-growing and air pollution data collection project with their children, who were already participating in a home-school program.

This water dispenser uses smart technology for a clean drink

Innovative solutions are essential for removing petroleum-based plastics from our daily life. Bevi, a bubbly, bottleless water dispenser for offices and commercial spaces, is dedicated to offering a variety of drink options, sans the plastic bottle. Bevi currently has two models of water dispensers. The Standup 2.0 is a floor model much like the size and shape of a traditional water cooler. However, Bevi goes sustainable by tapping into the existing water supply. Then it adds technology with WiFi driven smart features. Users can choose from bubbly or plain water, add caffeine or electrolytes and create flavor combinations with each serving. The Bevi Standup 2.0 also dispenses ambient or hot water. The screen displays nutritional information such as the amount of sugar, caffeine and calories in your selection. The countertop model offers a streamlined selection of the same options, but takes up less space. Related: FreeWater is the startup connecting people to fre...
