3D-printed clay tiles designed to restore coral reefs

Architects and marine scientists at the University of Hong Kong (HKU) have jointly developed a novel method for coral restoration making use of specially designed 3D printed artificial ‘reef tiles’ for attachment by corals to enhance their chance of survival in the Hoi Ha Wan Marine Park in Hong Kong waters.

The artificial reef tiles are specially designed to aid coral restoration by providing a structurally complex foundation for coral attachment and to prevent sedimentation, one of the major threats to corals. They provide anchors for corals of opportunity, i.e. dislodged coral fragments that are unlikely to survive on their own, giving them a second chance to thrive.

The 128 pieces of reef tile with a diameter of 600mm were printed through a robotic 3D clay printing method with generic terracotta clay and then fired at 1125 degrees Celsius. The design was inspired by the patterns typical to corals and integrated several performative aspects addressing the specific conditions in Hong Kong waters.In addition to the novel design of the tiles, the materials used are more eco-friendly than the conventional use of concrete and metal. The tiles were printed in clay and then hardened to terracotta (ceramic) in a kiln. The team plans to expand their collaboration to new designs with additional functions for seabed restoration in the region.

Skip Google for Research

As Google has worked to overtake the internet, its search algorithm has not just gotten worse.  It has been designed to prioritize advertisers and popular pages often times excluding pages and content that better matches your search terms 

As a writer in need of information for my stories, I find this unacceptable.  As a proponent of availability of information so the populace can actually educate itself, it is unforgivable.

Below is a concise list of useful research sites compiled by Edward Clark over on Facebook. I was familiar with some, but not all of these.

this was under a puppet history video

A member of anti-riot police who has arrested a student shoots directly at an Iranian citizen when he notices he is being filmed.

In the city of Ardabil, Iran, security forces of the Islamic Republic attacked a school and 7 students were seriously injured. The students were taken to the hospital, but unfortunately one of them died due to internal bleeding.

“X bodily fluid is just filtered blood!” buddy I hate to break it to you but ALL of the fluids in your body are filtered blood. Your circulatory system is how water gets around your body. It all comes out of the blood (or lymph, which is just filtered blood).
