GlLOBAL CITYOver the years population has grown exponentially creating high density problems such as material and energy waste and conflicts. To reduce density instead of decrease population.. just create a global structure to have more space.The “geostructure” floats around the world without touching the ground . It allows to not occupy Earth’s surface for new constructions, project digital written and images to communicate messages, info and ideas and see in real time what is happening in different parts of the world.The city of the future is a “Global city” all around the planet, a single space where everybody live in. A unique network for a global economy,energy and communication.In the contemporary society people live in different cities of different size creating different needs. In a future “Global city” all around the planet, needs will become common so a common public structure willmanage it. It will provide equal energy in different place of the planet creating a unique system for the whole population.The “Geo-structure” use renewable energy all around the planet creating an international ntelligent system that use solar photovoltaic panels in the warm places of the Earth giving energy also to cold places, and it use wind energy in windy places giving energy to places where there is no wind enough.The real time data transfer modify the city of the future and the people living in it. This create a new kind of space where all data and news are spread on digital screens and holograms changing at the same time human life style. It allows to ommunicate either for private, public or commercial purposes in an immediate way in every part of the planet and this lead to shorten distances. All people in the world is linked by a network of information contributing to create a global knowledge and culture.The city of the future is unique single where everybody are connected and equals among each other leading to the extincion of conflicts and development of a global international culture.
