This is the first article in the journal, and it answers the question people ask first: why is a brick project a nonprofit? The short answer is that the brick was never the point.
The bigger objective is self-sustaining ocean communities
One third of the world's people live on the coast. Rising seas will take the homes of hundreds of millions of them in the next thirty years, and most of them cannot afford a ticket to Mars. SeaBrick is a way for coastal communities to build out into the water instead of retreating from it. Docks and platforms first; then floating homes, and in time whole communities. Bricks are just the hardware from which those communities will be built.
A mission like that needs an owner that cannot be bought
A company has to sell, and sooner or later a company gets sold. So on 17 February 2022 SeaBrick Society was incorporated as a Canadian not-for-profit with one purpose;
To promote innovation and standards around environmentally sustainable marine infrastructure building materials.
The Society holds the SeaBrick form and the research. Related companies make and sell what comes out of it. The mission stays where it cannot be bought.
Community ownership, community control
The long-term vision is a decentralized, cooperative manufacturing ecosystem: low-tech production plants that ship in a container, so that communities affected by climate change can build their own floating infrastructure from materials at hand. The means of long-term production belong with the people who need it most. That is what the Society is for, and the rest of the journal is the record of getting there.
