Imagine cities encircling the globe that would configure themselves to these fractals so that when one ventured into space one would have a home that is beautiful to come back to and live in for all aspects of existence:

The cities would be organized using molecular structure as blueprints so connected dome and spheriod shapes would be the norm.   Half house half oxygen producing, food producing greenhouse.  Creating a sustainable standard for food travel time.

Tropical fruits could be cultivated in colder climates because of these massive dome (geotangent) green houses that again would be constructed using molecules as blueprints.  This particular structure resembles water.

Maybe these domes are to be the future of architecture on this planet as they use 30% fewer material resources to cover the same amount of space as a square building.  And they look kinda cool too.

These could be the homes and businesses...

Cal Earth Domes

These domes can be built in under a day, cost $41,000, and are 90% more energy efficient than a conventioanl dwelling.

One could even incorporate the two with homes attached to greenhouses growing food or decorative plants

these are known as Earthships   www.earthship.org www.earthship.com  www.earthshipbiotecture.com

Or have the trees growing around encircling the house

while plants are grown inside as well.

One could incorporate plants and trees into every aspect of everyday life.  Fast food resaurants could have tropical gardens to eat in.  Homes again could also have tropical gardens.  All businesses would be required to have enough flora inside and outside to provide oxygen and air cleaning power to equalize the amount of pollution they were responsible for.

All polluting industries would be placed in large domes and biological tools would be used to get rid of pollution using indoor constructed wetlands and algae scrubbers.    www.oceanarks.org
