City urbanism has some assets of water foam or bubbles. Composed with cells. Each has different shape or size and together create a city without a cars or buildings. City in which are these two components combined in one. Cells are able of hovering, flying and shape changing. This brings many opportunities for people and city urbanism to adapt.
Thanks to the new technologies, such as 3D print, fine energy and waste recycling and Internet of Evereything communication, there is no need of any solid infrastructure. City is simplified to realtime adaptable swarm of autonomous and self-sufficient cells. Transport of people an goods in the city is reduced to minimum, because there is less need. All thing you can print at home, other stuff is delivered by drones. People can travel by their Interspace cells, but short distances are overcome by walking. This makes city more healthier, more nature-friendly and in fact it creates city of short distances.
Interspace cell is fully movable. It is able to hover and fly. With this abilities, the swarms of these cells are composed to various groups. It can establish various city swarms, always movable or even entire flying city. The cells are equipped with the ionocraft propulsion and powered by sunlight. Energy from sun is harvested by powerful graphene-based photovoltaic layers, which are integrated in coating.
Ionocraft propulsion is based on phenomenon called “ionic wind” or EHD - Electrohydrodynamic thrust . This produces thrust in air without any combustion or moving parts.
Ionocraft was widely tested in 1960s as a replacement for helicopters. The project has failed due to energy requirements.
The principle is very simple. It consists of two parallel conductive electrodes. When this arrangement is powered by high voltage, it produces thrust.
This system is popular among "anti-gravity" or "electrogravitics" proponents, due to research of Thomas Towsend Brown, who built these devices in the 1920s and incorrectly believed, that he had found a way to modify gravity using electric fields
But it is not an anti-gravity device. The term "lifter" is more accurate description, beacuse it produces lift using the same basic principle as a rocket
EHD generators are integrated in ribs all around the cell. So it is able to fly in every direction and also levitate in one place.
The hovering cell has basic torus-like shape, which can be modified in size and profile. During the flight, the cell is reshaped in more aerodynamic form.
Interspace Airborne is a complex system, that combines house and car in one cell. Basic torus-like shape is suitable for easy expanding or shrinking. While in the high density city, its size is minimal. In a free landscape, it can expand and and you can use the atrium inside. Its facade has 20 series of parts, which are able to disconnect and connect with another cell again.
Load-bearing ribs made from graphene nanotubes are used as a skeleton. It carries entire load.
These ribs has multiple functions. Except from carrying entire cell, it also forms its shape.
Another advantage of graphene-based materials is an ability of store electric energy. This technology makes from entire cell a big battery.
Between the ribs are stretched graphene-based membranes. This coating has also ability store energy. But much more important function is gathering energy. Graphene is also very capable photo-sensitive material. It can be used as a very effective photovoltaic layer. It works with entire light spectrum and even in low light. With this abilities, there is no need to power supply from any infrastructure.
Skeleton ribs have capability of stretching and shape changing. Graphene-based shape memory materials can extend or bend itself by shape programming.
Ribs are also capable of unplug and connect with another. This is widely used as the system of connecting with another cell.
