Global Renaissance Project Spiral Unified Field Architecture
We have known for a long time the structural order of the triangle, square and circle, and so we have designed and built structures based on these three archetypal forms. We now know the structural order of the fourth archetypal form, the spiral form, and so can now begin to design and build in structural harmony with Nature. To begin we need only learn how to fabricate a single architectural element. It’s called the Spiral Architecture Element 45. Multiples of this unique building … Read more
‘Smart’ buildings to clean polluted air Design for buildings that filter the air
China-based architect Alexander Balchin has designed a building that can clean polluted air. The tower is designed to filter air for several city blocks outside. Dirty air pulled into a central chimney would be cleaned using systems commonly used in coal power plants. 'The PM2.5 particles can be collected and even reused, as they are almost completely carbon,' Balchin writes. 'This process alone provides eight and a half million cubic meters of clean air per year, enough air for one square … Read more
Algea absorb air pollution Algea farms around highways
Algae consume sunlight and CO2 and spit out oxygen. Therefore places with high emissions are the perfect growing area. This interesting microorganism inspired a group of Dutch and French designers, who proposed to set up an algae farm on top of a highway in Switzerland. It is a brilliant way to filter the pollution in the urban areas. … Read more
