Dr. Ido Sella and Shimrit Perkol-Finkel , two marine biologists solving one of the least ‘sexy’ problems in the world.
The problem is concrete. Not many people know this but concrete this rock, solid, grey, boring structure is great to build houses but is terrible for the ocean. Marine life is suffering the fish is no longer around the oysters and corals are disappearing and the concrete is lifeless for decades. Concrete is the most consumed material in the world after water. And that’s where these guys come in to solve the lifeless concrete problem.
They spent the majority of their lives researching, studying, diving and learning about the oceans. They spent 20 years doing this so far. After many years, they came up with an amazing technology. That turns concrete from this. It’s a unique unit and built with new added materials. It is designed with tiny holes for the small fish to live in them. It is eco-friendly and it’s even stronger than normal concrete. So when you put this new concrete in the water for months the most amazing thing happens. Small fish live around it. sea weed grow on top of it. Corals and oysters appear round it and marine life thrives. And all of this brings the concrete to life.
Oysters are growing on the designs so what you’re seeing here is biology that grows on the concrete and it actually makes the concrete stronger and it’s called bio protection. Lifeless oceans could turn into an amazing eco-system for humans and the animals alike.
That’s why these guys are designing ports, breakwaters, sea beds, and seawalls that are built with the ocean in mind. Concrete is not a sexy problem and solving it can be tough, expensive, challenging and take decades. So far they installed their concrete in five different countries in five different waters. And the results are amazing. We cast them and design them and they are placed in Brooklyn bridge park in New York. Where they bring life to this urban environment. Here they create hot-spots for biology.
And when they install missions more of these around the oceans they will change the world one block at a time. Source: Nas Daily (From Youtube)
