Top 10 inventions are contributing to the 'salvation' of the ocean, the number 3 created by a new girl in grade 6!

ECOncrete - Marine ecological concrete

Did you know that concrete is the second most consumed material in the world, after only water? Not only that, concrete has a very bad influence on the ecosystem. When exposed to long sea water, concrete will release harmful chemicals to nearby living organisms.

Therefore, a company based in Israel has developed ECOncrete. This type of ecological concrete has the same effect as ordinary concrete but is made up of other environmentally friendly materials. In addition, they have a structure with many holes to simulate corals, allowing undersea fish to live inside.

Wrap the can of edible water

Surely everyone will remember the image of marine creatures dying from plastic waste, birds pinched by rubber bands, or the most famous is the video of a turtle with a straw in the nostrils.

To increase public awareness and reduce the negative impact of rubbish, SaltWater Brewery - a company based in Florida, USA - has created a completely new version of beer can. Organic materials allow them to dissolve quickly in seawater, leaving no toxic chemicals behind. In addition, if the marine creatures have accidentally eaten, it will not cause any negative effects.

Robots detect and filter plastic from water

Anna Du, a freshman in grade 6, was able to create a machine with unexpected effects. The robot also helped Anna to reach the final of the Discovery Education 3M contest in the Children's Science field.

The robot is composed of two main components: a navigation system to swim in the water and a high-resolution infrared camera to find microscopic particles. From the outside, the robot looks like a pile of discarded plastic pipes, but in fact, it works very effectively, quickly clearing micro-particles of water in the water.

Currently, you can buy books and donate funds to support Anna Du's project at KickStarter website.

Seabin ocean trash

This 'trash' feels like a 'black hole' in the middle of the sea, but instead of sucking everything, it just sucks the garbage floating on the water. This model has now been widely applied and proved extremely effective in filtering and removing plastic waste on the coast. Seabin is even used to filter oil from the surface of the water thanks to the special inner filter.

Seabin can filter nearly 2 tons of waste per day.

Seavax suction boat

The vacuuming boats are still in beta. In the future, the system of Seavax boats can surf on the open sea, go anywhere to suck garbage there and have a compartment of about 150 tons of waste. In addition, because they can be powered by electricity from solar and wind power, they are even more suitable for environmental purposes.

Ocean Cleanup's huge garbage filter system

The Ocean Cleanup cleanup project is the result of 5 years of development by a Dutch scientist. His filter system, nicknamed Wilson, is composed of giant nets, attached to plastic pipes floating on the surface of the water, and collects all kinds of waste under the sea.

Wilson is currently in the process of operating near Pacific Waste Island and is expected to reduce waste by 50% here.

Giant sunblock for corals

Sunlight contributes to life but can also make organisms disappear. The intense sun causes the water temperature to rise, leading to an increase in the acidity of the seawater and will eventually wipe out the near-surface reefs, such as the Great Barrier - the home of the Nemo fish in the popular Disney blockbuster. belong.

Biological sunblock made by new Australian scientists is made from calcium. They are both durable and easily biodegradable, keeping the ocean cool and reducing the exposure of corals to sunlight.

Artificial corals

Artificial reefs simulate the shape of real corals with gaps, holes for organisms to attach to and live inside. This material will create a better living environment, contributing to creating food sources, increasing the quality of seawater for the redevelopment of fish, shrimp, crab . populations.

In vitro fertilization for . corals

Corals are an extremely important part of marine ecosystems, so there are three inventions on this list to protect them. The third idea sounds strange, confusing but extremely effective.

Scientists can take samples of coral larvae in the Philippines and Great Barrier coral teeth, then propagate them with in vitro fertilization. The number of larvae after fertilization can reach millions, are taken back to the dying coral reefs and carefully protected from ocean currents, sunlight and El Nino phenomenon.

Hoola non-plastic food wrap

Forget disposable plastic films, you'll want to use Hoola to wrap food. This product was developed from a material called Notpla (Not Plastic), a combination of seaweed and other plants. Hoola can wrap the whole water inside without tearing, and is edible and completely environmentally friendly.
