Cement, a vast source of planet-warming carbon dioxide, could be transformed into a means of stripping the greenhouse gas from the atmosphere, thanks to an innovation from British engineers.

The new environmentally friendly formulation means the cement industry could change from being a “significant emitter to a significant absorber of CO2,” says Nikolaos Vlasopoulos, chief scientist at London-based Novacem, whose invention has garnered support and funding from industry and environmentalists.

The new cement, which uses a different raw material, certainly has a vast potential market. Making the 2bn tonnes of cement used globally every year pumps out 5% of the world’s CO2 emissions – more than the entire aviation industry. And the long-term trends are upwards: a recent report by the French bank Credit Agricole estimated that, by 2020, demand for cement will increase by 50% compared to today.

Seasteads are permanent, stationary structures specifically designed for long-term ocean living. Entrants into the contest were provided with a 3-D model of TSI’s patent-pending base platform, on which they built creative architectural designs for a new society of ocean pioneers. The specifics of the design, aesthetics, and intended use were entirely up to each designer.

Seasteading.org recently had a contest for designers to construct a seastead using 3-D modeling software. Above and below are some of the winners. Enjoy!
