The bicycle is designed to generate energy when riding and this energy can be used as currency to pay for your bus rides. The bike electronically folds into the bus seat storage mode for space and weight efficiency and to fit on the bike stand. Bike stands can be found at the bus stops where the bikes will be stored securely in order to collect energy from the sun and wind. Moreover, it contributes energy to the bus system that was generated during riding and stored in inner batteries. Finally, the energy will be accumulated from all the bus stops into the London Garden network system, which is the Universal Electricity Network of this concept.

This concept has been driven from the need for zero-pollution, efficient and affordable cars for the future community and enjoying the freedom of a ride. The ATNMBL is designed as a self-driving car with artificial intelligence which arrive to you with just a phone call. The standing-height entrance has an electric sliding glass door and upon entering, you will be asked for your desired destination. The comprehensive and innovative voice recognition system of this vehicle along with a touch screen remote and slide up display, it can offer a wide range of tour planning, detailed performance setting and enjoyable ride sharing.

The overall arrangement of the interior of ATNMBL is very much familiar with conventional living room sitting including side chair, a couch and a low table. Up to seven passengers can sit towards each other and can see outside through large floor-to-ceiling windows on both sides. From outside, this vehicle looks like micro-architecture with a large window, pitched room and asymmetrical shape from every view without any reference to past automobile designs.

A considerable amount of typical car space is blocked with the engine and drive train, while, the mechanical components of ATNMBL are simplified and densely packed, providing more interior space. Each wheel contains electric motors which provide all-wheel drive. The power storing mechanism is located beneath the floor; moreover, alternative solar energy can be obtained from the roof-top solar panels. The front and rear end contains an array of tail lights, headlights and sensors.

DRAGONFLY, A METABOLIC FARM FOR URBAN AGRICULTURE

2009 : 800 MILLION OF URBAN FARMERS FOR RESPONSIBLE ECO-CITIES

The world of fast-food and frozen food is over! The urban keen interest of the beginning of our Century turns toward the garden flat bringing back the countryside in our overcrowded cities fighting from now on for a community urban agriculture able to contribute to the durability of the city and to rethink the food production.

On the roofs, terraces, balconies, in the hollow of the non-built public spaces, in the interior yards and the suspended greenhouses, the eco-warrior aspires to escape from its competitive and consumeristic universe imposed by the laws of the market. He desires to cultivate its immediate landscape so as to better take root in the ground by creating his own ecologic and alimentary biodiversity. The consumer becomes from then on producer and the garden inhabitant !

From the Parisian « worker gardens » to the « community gardens » of New York going though Muscovite « vegetable squares », eight hundred million of urban farmers, i.e. more than one human being out of ten, consume nowadays chlorophyllous products from these cosmopolitan kitchen gardens. These new gardens, aware of the emergency to reduce our fuel consumption and the necessity to modify our behaviour facing the climatic changes, decrease thus their environmental impact and build eco-responsible cities on a community way.

2025 : 5.5 BILLION OF CITY SLICKERS FACING THE FOOD CHALLENGE OF THE 21ST CENTURY

According to the PNUD (Programme of the United Nations for the Development), the worldwide urban population will go from 3.1 billion of inhabitants in 2009 up to 5.5 billion of inhabitants within 2025. Looking for a positive energetic assessment, the contemporary city aims within fifteen years at producing cleanly and intensively more energy than it consumes so as to pack this urban exodus! It develops therefore the urban agriculture to become food self-sufficient by recycling at the same time its liquid waste by phyto-purification, its solid waste in fertilizers by composting and by producing energy by biomass, photovoltaic cells and other renewable energies (thermic solar, photovoltaic solar, wind, tide-turbine energies…).

In order to avoid the asphixiation of the planet and the feeding of its 9 billion of inhabitants within 2050, it deals thus with reinventing the traditional energetic pattern between the city and the countryside between western countries, emerging countries and developing countries. This sums up as following: on the one hand import of natural and food resources, and on the other hand export of waste and pollution. The ecologic city aims at reintegrating the farming function on the urban scale by emphasizing the role of the urban agriculture in the use and the reuse of natural resources and biodegradable waste so as to close the loop of ecologic flows.

The urban agriculture can feed the city without any pesticide or chemical fungicide (whose toxicity is proved on the human being : cancer, sterility…), and make it less food dependant of its backcountry or other regions of the world. Organising the distribution of fresh products in short circuits, that means linked directly with the consumer, the urban agriculture complete thus the traditional agriculture. In addition to the nutritive quality of the produced and consumed food, the urban agriculture is also a growth lever of the urban unemployment market and the local economy. It is used directly as a social link in the conciliation of the primary needs of the newcomers with the challenge of their integration in the life of the city, fighting thus against poverty and exclusion. On the sanitary level, this farm approach presents also an interesting potential for the decontamination of polluted grounds and undergrounds as well as for he purification of the polluted atmosphere in CO2.

Due to the fuel crisis and climatical change, the rural agriculture of the western countries must answer to the worldwide food crisis of the developing countries and mainly Africa. Its role is from now on to produce (with an increase estimated of 60% within 2050) all the foodstuffs transportable by boat such as cereals or corn. This is based on the evolution of the science and the most advanced biotechnologies. In addition to this nutritious role, the rural agriculture is newly challenged to recycle its own culture rebus for the green chemistry in order to produce the bio fuel called “second generation fuel” using the energy of non-consumable materials from the plants, that means fibres such as celluloses.

DRAGONFLY, A NOURISHING VERTICALY CULTIVATED CENTRAL PARK

The architecture has to be in the service of this new agriculture and to design this new social desire in this context of ecologic mutation and food autonomy! The Dragonfly project suggests therefore building a prototype of urban farm offering around a mixed programme of housing, offices and laboratories in ecological engineering, farming spaces which are vertically laid out in several floors and partly cultivated by its own inhabitants. This vertical farm sets up all the sustainable applications in organic agriculture based on the intensive production varied according to the rhythm of the seasons. This nourishing agriculture is furthermore in favour of the reuse of biodegradable waste and the keeping of energy and renewable resources for a planning of ecosystemic densification.

Floor by floor, the tower superposes not only stock farming ensuring the production of meat, milk, poultry and eggs but also farming grounds, true biological reactors continuously regenerated with organic humus. It diversifies the cultivated varieties to avoid the washing of stratums of soft substratum. Thus, the cultures succeed one another vertically according to their agronomical ability to provide some elements of the ground between the essences that are sowed and harvested. The tower, true living organism, becomes thus metabolic and self-sufficient in water, energy, and bio-fertilizing. Nothing is lost; everything is recyclable to a continuous auto-feeding!

A BIONIC AND ENERGETICALLY SELF-SUFFICIENT ARCHITECTURE
The architecture of Dragonfly prototype suggests reinventing the vertical building (that outlined the urbanistic booming of New York City since the 19th Century) as structurally and functionally as ecologically and energetically.

To ensure the social diversity and a permanent life cycle (24h/24) in the tower, the mixed programmation is mainly laid out around two poles of housing and work places. Around housings, offices and research laboratories as well as the most private to the most public agricultural and leisure spaces are designed in gardens, kitchen gardens, orchards, meadows, rice fields, farms and suspended fields. The distribution of flows is made around a true safe spine spreading in loop the numerous elevators, the goods elevators and stair wells serving all the levels by separating simultaneously the inputs and the outputs recycled from plants, animals and human beings.

Architecturally, the functional organisation is represented by two oblong towers symetrically arranged in pair around a huge climatic greenhouse that links them and deploys itself between two crystalline wings. These very light wings in glass and steel retake the loads of the building and are directly inspired from the structure of the dragonfly wings coming from the family of “Odonata Anisoptera” whose transparent membrane is very finely nervured. Two inhabited rings buttress around these wings. Their organically chiselled exo-structure accommodates the inter-climatic spaces that receive the agrarian cultures. They buttress.

The whole set forms «double layer» architecture in bee nest mesh that exploits the solar passive energy at its maximum level, by accumulating the warm air in the winter in the thickness of the exo-structure, and by cooling the atmosphere by natural ventilation and by evapo-perpiration of the plants in the summer. Protecting thus the cultures from climatic changes in New York (from -25.5°C in the winter to +41°C in the summer), these plug spaces are useful to reflect on the agriculture not anymore in terms of surface area but really in terms of volume. Actually, whereas grounds nourish orchards, each wall and each ceiling are metamorphosed into three-dimensional kitchen gardens. The interior frontages of the housing and offices throw towards the skyline of New York the cantilever of their hydrophonic balconies with hexagonal section thanks to what it multiplies the culture layers by floors. The vegetation abounds, the earth is swarming of insects and animals are freely brought up in holding tanks by urban consumers with low income. The architecture becomes eatable!

The 2030 Honda’s luxury sports sedan, Zeppelin Concept, was designed with a design direction of “High-tech Dynamic”, inspired from an airship. The feeling of mass has been completed by applying design elements of aerodynamic form from an airship, and on top of that, expressed the distinct powerful image of Honda. Especially the asymmetrical main character line extends from the front hood along the roof line, to all the way back at the rear end. Hexagonal front grille and thick nose volume and the protruding horizontal lamp completes the dynamic face.

The interior was also inspired from the airship, reminiscent of a cozy salon or a first-class seat of an airplane. There is no dashboard in Zeppelin. All the necessary information and other elements needed for driving is displayed on the inter panel of the car, and everything is controlled with only the minimum physical movement due to the use of voice recognition technology. The seat position can be changed freely. That front row seat can rotate 360 degrees and so when the car is not moving, the front row seat and the back row seat can face each other. This makes it possible for a brief meeting, enjoying tea and even working in the car, which could also provide a new experience to the family or a fellow passenger. Due to the display environment on the windshield it was possible to use the angle of windshield and the shape of the A-pillar as a design element of the exterior without any restriction.

[Press Release]
The future headquarters of Antwerp Port Authority will be designed by the London firm of Zaha Hadid Architects. The choice of architect was made at the Port Authority board meeting on 13 January. The new Port House will occupy the site of the technical services building on quay 63.

The Port Authority aims to make its operations more efficient by centralising the administrative and technical services which are now divided between the Port House and quay 63. The new headquarters will also solve the pressing shortage of workspace in the present Port House on the Entrepot quay. Some 500 people will be able to move into the new building when it is completed in 2013.

In addition to offering better accommodation, the future Port House will contribute to further development and upgrading of the part of the city known as Het Eilandje. The brief for the new building specified that it had to symbolise the Port of Antwerp as a world port and economic driver of Flanders and the Antwerp area. It also had to be built according to the principles of sustainability.

In selecting the architect it was decided to use the Open Call for Tender procedure of the Flemish Government Architect’s team. The procedure was launched in December 2007, and nearly 100 architectural firms responded. A shortlist of five firms was chosen:

• Consortium of TV A2O Architecten / Atelier Kempe Thill / Marcq & Roba / BEG from Hassel, Belgium
• Vier Arquitectos from La Coruña, Spain
• Xaveer De Geyter Architects from Brussels
• Zaha Hadid Architects from London
• Rapp + Rapp from Rotterdam

The jury/board of directors finally opted for the proposal by Zaha Hadid Architects, because:

• The design preserves as much as possible of the dignity of the present building as a monument, adding a new object to the site;
• The board and its advisors had confidence in a team such as Zaha Hadid Architects being able to further develop the project so as to achieve a high quality end result that can act as a “shop window” for the Port Authority.

The estimated construction cost is 31.5 million euros excluding VAT and architect’s fees. This includes all the work for an office building with around 12,000 m² of floorspace for around 500 people, together with underground parking for 300 or so cars.

The new building fits in with the Port Authority’s future-oriented investment policy. At the same board meeting it was also decided to purchase four tugs as part of a renewal series of nine. And of course there will be further investments in infrastructure for expansion and renovation of the port. The various Flemish port authorities are currently holding discussions with the Flemish Government about financing for basic port infrastructure.
The new Port House forms part of a programme of improvements to the Port Authority’s own buildings. In addition to various renovation and new construction work that has already been carried out, a public call for tender has been issued for the new VTS (Vehicle Traffic Service) building beside the Zandvliet lock.

Design proposal

The design team from Zaha Hadid Architects proposed a very dynamic architecture that strikes up a dialogue with the Oosterweel road link, with the Lange Wapper bridge forming a backdrop to the New Port House. With its unique design, its facade architecture and its height of 46 metres, the new Port Authority will be an iconic building, visible from many different directions.

The concept is a free interpretation of a beam-shaped volume raised above the existing fire brigade building and supported on three sculptured concrete pillars housing the stairs and lifts. Two of the pillars are situated on the covered inner courtyard of the firehouse, while the third is located beside an external support point and consists of a panoramic lift shaft.
The new volume is oriented North-South parallel to the Kattendijk dock. The head of the building on the South side is a frame that looks towards the city and clearly marks the start of the port area.
The outside walls are made up of glass triangles, some transparent and some reflecting. These do not all lie in the same plane but are rotated slightly with respect to one another, creating an attractive reflecting play of incoming light in a reference to Antwerp’s diamond industry.

The present firehouse will be kept free of building all around, so that the four outside walls will be fully respected. As for the arrangement of the inside spaces, consultations will be held with Flanders Real Estate Heritage and the Monuments department of the City of Antwerp to determine whether open-plan offices (as laid down in the schedule of requirements) are possible, either partly of throughout.

The inner courtyard will be roofed over at the height of the second story so as to create an air-conditioned inside space. This central entrance hall will be considered as a semi-public space, with various enquiry desks (Personnel department, Harbourmaster’s Office, Planning Permission & Environment Permit office and Port Dues payment desk) integrated in the inside wall portals.

A sculptural, sloping roof unites an underground lobby with the covered inner court. Access to the underground car park is an important aspect of the overall concept, with the loading & unloading bays and the refuse handling facilities also located here. The car park has space for 300 or so cars and consists of a single underground level. The design of the square can be arranged so that daylight is allowed to enter. The above-ground layout forms part of a design project that is being carried out in consultation with the city departments responsible, with the main imperative being to “preserve the visual quality of the outside spaces in the Het Eilandje area.”

The open plan offices are indeed very open, so that office staff will have a great impression of space with a view along the various outside walls. The concept for the open plan office also allows for small areas in which to hold meetings, along with separate study offices.

Text from David:
Transportation is a key factor in our urban environments and most of our cities are now developed to match the scale and needs of cars, and car users. This reality raises issues regarding sustainability and environment, energy consumption and quality of life.

So, “How can public and personal transports be redefined in a sustainable way, delivering a sense of personal space and independence to its users?” This was the title of my Master of Science in Design and Transport Thesis, concluded in Coventry University, UK, with Distinction, in September 2008.

In other words, the aim of this project was to develop guidelines and a holistic solution for a new system of urban transport, composed of vehicle and infrastructure, in a sustainable way and adaptable to various urban environments.

To develop the project I needed information about: user’s behaviors and explanations for them; main trends; analysis of existing solutions and identification of their problems; definition of applicable technologies in a sustainable manner in a near future. This information was gathered through an online questionnaire, statistical data from several sources, literary research, internet articles, pictures, video and expert interviews and then compiled in my final report.

Preliminary research indicated that several attempts to tackle the issue of mass transportation are being tested and implemented throughout the biggest cities on Earth. Several solutions exist already, but people always seem to give preference to a personal vehicle of some kind to move, commute or make quick trips. Only when there is no other choice, people seem to engage in public transportation. Personal transport is the preferred mode of use and this is a trend that keeps increasing.

The conclusion of the thesis report was composed of guidelines and design specifications that served as basis for the development of a new type of transportation that is truly sustainable and that meets people’s requirements. This generic solution was exemplified through a typical design project that will act as future reference and that goes by the name of “SCARAB”.

PROJECT DESCRIPTION:
VEHICLE:
- The vehicle allows users to have freedom of use much like a motorcycle but with the convenience of having an enclosed private space and luggage compartments.
- The vehicle can be operated in several different positions depending on speed. It is parked vertically for easy ingress and egress and optimization of public space. When in speed position, the vehicle also tilts when curving or changing direction.
- When circulating in dedicated pathways, the SCARAB is controlled by a centralized computer or by a traffic management centre. Outside of the dedicated pathways the SCARAB is controlled by the user just like any other vehicle.

VEHICLE SPECS:
-The vehicle is composed of interchangeable modules that can be customized by the potential buyer/user.
-Powerpack module composed of a permanent battery plus 3 options for the main energy pack (battery, biofuel ICE or a fuel cell).
-4 wheel drive through electric brushless in-wheel motors with directdrive.
-Wheels with regenerative braking through EW Brakes.
-Drive by wire and tactile HUD embedded in the Lexan canopy.
-Structural elements in Carbon-Aramid composite.
-Embedded sensors, Lidar, radar, transponders, GPS. These serve to exchange information with the system, with other drivers and to have precise location data.

INFRASTRUCTURE:
-Communication nodes spread through roadways and traffic management centres in major conurbations.
-Dedicated paths with electromagnetic transponders embedded in the road.
-Parking facilities with solar/wind power generators.
-High speed/long distance travel provided through a railroad interface (not yet developed).

SYSTEM:
-Renting of the vehicle or modules that allows for a private/public/mixed utilization and transport access for people with less financial resources.
-Doesn’t need new infrastructures (uses the existing roads).
-Is backward compatible with current transport systems and uses current day technologies.

NUVU: RESHAPING THE CITY

Within just a few years, cities all over the world will be at near bursting point. If mankind wants to retain the level of personal mobility it currently enjoys – and if the city is to survive – the only way forward is for a radical rethink of the type of cars driven there. One solution could be a car like Nuvu, designed for the city of the not-too-distant future.

“Nuvu is literally a ‘new view’ at the future of the city car. It is electric, of course, but as far as Nissan is concerned, for tomorrow’s city cars that is a given. No, the most important aspect of Nuvu is the interior design which provides great comfort and space in an intelligent package designed to make best use of our crowded roads and limited parking slots.”

François Bancon, General Manager, Exploratory and Advance Planning Department, Product Strategy and Product Planning Division, Nissan Motor Co., Ltd.

Overview
There is about to be a seismic shift in the urban landscape. Within the next five to seven years, some 55 percent of the world’s population will live in the city, threatening total gridlock. Unless something is done, the irony of the phrase ‘personal mobility’ will be self-evident.

Look around at the cars in a typical city traffic jam today and the vast majority will have only one occupant and four empty seats. Some might have two occupants, a few three. But find one with four occupants or more and you’ll be doing very well.

Today, we buy a family car knowing that we’ll only ever need to use it to its full potential one or perhaps two percent of the time. Tomorrow, things will be different. Tomorrow, things have to be different.

“There is a new generation coming up who, finally, are questioning why we do the things we do. They are asking themselves, for example, why they are buying a large car when they know that for 99 percent of the time they will be in it on their own,” says François Bancon, General Manager, Exploratory and Advance Planning Department, Product Strategy and Product Planning Division, Nissan Motor Co., Ltd.

“It is our job to provide personal transportation that is better suited to people’s needs and to what the environment – in all senses – can cope with.”

Nissan’s vision for the future of urban transportation is encapsulated in Nuvu, a ‘new view’ of the type of car we will be driving in the middle of the next decade. Compact – it’s just 3 metres long – Nuvu is a concept vehicle with unique 2+1 seating. It is aimed at urban dwellers who don’t want to compromise on their personal freedom or their comfort, yet who appreciate that ‘something has to give.’

Nuvu is agile, easy to drive, even easier to park. And it is, of course, an electric vehicle (EV). As Bancon says: “We believe zero emission vehicles are one of the key solutions for tomorrow’s city car.”

Nuvu is described as a moving oasis, a haven of green tranquillity in the urban jungle. To underline this message, Nuvu incorporates a witty representation of its green credentials: across its all-glass roof are a dozen or so small solar panels. Shaped like leaves on a branch, the power they generate is fed to the battery using a ‘tree trunk’ within the car as a conduit. Nuvu also uses natural, organic and recycled materials within the cabin.

Nissan has already announced plans to introduce an all-electric car in Japan and the US in 2010 and to mass-market it globally in 2012. Nuvu is not that car, though it does share some of the technology that will feature in the planned production vehicle. Rather, it is a concept of how a Nissan EV might look in the near future.

In the longer term, Nissan foresees a future based around a line-up of zero emission vehicles regardless of their size, category and usage. Nuvu – or its production equivalent – is just one element of this emission-free future.

Nuvu in detail
The central thrust behind the development of Nuvu is not its motive power but its layout and use of space. Nuvu has been created for a city of the future, one that’s even more crowded than today.

That’s why it’s compact on the outside yet roomy on the inside. Built on a unique platform, it’s just 3 metres long and sits on a wheelbase of 1980 mm but is 1700 mm wide and 1550 mm tall to create a large and airy cabin.

Interior package
These dimensions provide all the interior room needed for the vast majority of city journeys. Nuvu has two regular seats and a third occasional chair that can be folded down when required. But, unlike some two-seater city cars currently on the market, it is a thoroughly practical proposition with an integral luggage area providing sufficient space for a typical supermarket or shopping expedition.

“It is a real car,” says Bancon. “There would be no disadvantages to using a Nuvu everyday. For the vast majority of users, three seats are more than enough most of the time.”

The packaging is designed to give priority to driver comfort with C-segment levels of space and the flexibility to invite one or two passengers on board. Cabin layout places the regular passenger seat beside but largely behind the driver’s seat, allowing the passenger to stretch right out. Ahead of this seat is a third occasional chair which, when not in use, is folded away into the dashboard assembly. But even when the third seat is in use, there remains sufficient legroom for both passengers.

In the interests of saving both weight and space, the third seat has a centre section made from hardwearing yet comfortable netting. This hammock-like approach also has the benefit of allowing cool or warm air to circulate around the occupant’s body for extra comfort.

Shopping bags, briefcases and smaller items of luggage can be stowed behind the driver’s seat while if the driver is travelling solo, larger items can be stowed in the passenger footwall.

City car research
“We did a great deal of research into how people use their cars in the city. We found that for 90 percent of the time, the driver was alone. For five percent of the time there was one passenger and for four percent of the time there were two passengers. You can do the math to find out how often four or more people were in the car!” says Bancon.

“We gave the second seat much more room than normal because when you take one passenger in your car it is usually someone you love and you want to make sure he or she is being carried in outstanding comfort,” he adds.

Natural materials
Many of the materials used inside Nuvu reflect an increasing concern for the environment. The floor is made from wood fibres pressed into laminate sheets and is studded with rubber inserts made from recycled tyres for grip.

To create a light and bright interior, the windscreen and roof merge into one extended panel running virtually the entire length of the car. But undoubtedly the most unusual feature of the interior is the ‘energy tree’ which rises from the luggage compartment floor to the roof behind the driver’s seat.

Solar panels
The energy tree is shaped like a thin trunk. As it reaches daylight it branches out under the glass roof providing occupants with protection from bright sunlight… just like a real tree. And providing a visual reminder of Nuvu’s green credentials, covering the branches are dozens of small solar panels shaped like leaves.

The panels absorb energy from the sun which is then fed back down the energy tree and used to help recharge the battery and provide an extra power boost for the electric motor. As well as being genuinely green energy, it is estimated that the power generated via the solar panels will save the equivalent of one full overnight charge from mains electricity each month.

Driver controls are as simple as possible. All the major functions – steering, braking, transmission and throttle – are ‘By-Wire’ while the steering is controlled by an aircraft-style steering yoke: with just one turn from lock to lock, the steering is very direct for agility and manoeuvrability in the city. Nuvu’s turning circle is just 3.7 metres. Thanks to its wide track and the use of 16 inch 165/55 tyres mounted on lightweight, almost transparent, wheels, ride comfort, stability and agility is of the highest order.

There are two pedals – for stop and go – stalks for minor controls and a digital instrument panel with dials for speed, distance covered and battery range. The instrument panel itself is formed of layers – rather like an onion – and like the energy tree is another example of design inspired by nature. “We call it bio-mimicry,” says Bancon.

Rear view/parking monitor
Two screens on the dashboard display the view behind the car – there are no door mirrors to disturb the airflow, but small cameras – and double as monitors for the Around View Camera which give a bird’s eye view of the car when manoeuvering or parking.

Saving energy was the guiding force behind the use of low-energy LED head and tail lamps, while Nuvu’s heating and ventilation system filters and cleans the city air as it passes through the vehicle. Not only does it produce no emissions at source, but Nuvu actually helps clean up the city environment.

Exterior and interior design
“Nuvu’s design is further clear evidence of Nissan’s continued desire to challenge convention and to explore all the possibilities that the EV could bring us. In many ways it was inspired by our two most extreme EVs of recent times: Mixim and Pivo 2.

“Significantly, though, Nuvu delivers a more realistic interpretation of two of the most important aspects of its forerunners – the ‘Friendly Innovation’ found in Pivo 2 and the ‘Sports Dynamics’ central to Mixim

“The result? We have designed a radical concept car that with just a few changes could go into production tomorrow,” explains Masato Inoue, Chief Designer, Product Design Department, Nissan Motor Co., Ltd.

Developed by designers at Creative Box Inc. – Nissan’s design think-tank – Nuvu’s green house has flowing lines with gentle curves inspired by nature. The distinctive shape of the door glass on either side gives the impression of a hot air balloon that’s being gently inflated by pressure from within, while tropical fish inspired the profile of the side window graphics as a whole.

This contrast between the natural, fluid shape of the greenhouse and the strength implied by the solidity of the lower body gives Nuvu a feeling of quality rarely found in a compact car.

Colour and materials
Nuvu’s visual impact is further enhanced by its unique body colour. Developed by Nissan Design, the shade is officially called Soft Feel Sandy Gold.

Matching the ecological values of an electric vehicle, the moulded plastics and synthetic elements found inside a typical production car have been replaced by natural materials and organic alternatives, such as the wood fibres and rubber from car tyres used for the flooring. The result helps create a relaxed, warm atmosphere within Nuvu’s cabin.

During the design development stage, key targets were to develop an EV that encompassed obvious modernity with engaging ambience and a playful aspect – hence the energy tree. “You don’t need to be a car lover to fall in love with Nuvu,” adds Bancon.

EV drivetrain
Nuvu is more than a styling concept of a future EV. It is a fully working mobile test bed for much of the technology that will be used in Nissan’s production EV to be launched in 2010. For this reason elements of its technical specification are being kept secret for the time being.

The electric motor used in Nuvu is mounted at the rear of the vehicle and drives the back wheels, though neither its exact specification nor the power and torque figures are being released at this stage. A driving range of 125 kms and top speed of 120 km/h are being made public, however.

Li-Ion battery
Similarly although it can be revealed that the batteries used are of the latest laminated lithium-ion type and have a capacity of 140 Wh/kg (watt-hours per kilogram), the total capacity of the batteries and number of modules are not being disclosed at this stage.

Nissan began research into high output Li-Ion cells as long ago as 1992, but today development is carried out by Automotive Energy Supply Corp. (AESC), a joint venture company set up by Nissan and NEC Group.

Unlike a conventional lithium-ion battery with its bulky cylindrical cells, the laminated Li-Ion battery as used in Nuvu has thin laminated cells and fewer components overall. This boosts its power by a factor of 1.5 at the same time as halving its physical size. It also remains twice as efficient as a conventional cylindrical Li-Ion battery even after five years or 100,000 kms of continuous usage.

Another bonus of the compact cell construction is that a thin modular design is possible with a commensurate improvement in battery cooling efficiency. Higher power outputs are achieved through material improvements made to its lithium manganate positive electrode and carbon negative electrode. The use of chemically stable spinal-structured manganese for the positive electrode also helps ensure safe operation.

Its compact size allows the batteries to be mounted under the seats and the vehicle’s flat floor, thus helping to keep the centre of gravity as low as possible.

A quick charge from empty to full should take between 10 to 20 minutes while a full charge should take between three to four hours from a domestic 220V socket.

Typical users
“The people who will be drawn to a car like Nuvu are many and varied,” says Bancon. “It is a cross generational car and not a signature vehicle for one generation.

“There will be common threads, however. They will be early adopters but more importantly they regard themselves as urban citizens. They don’t just work or live in the city; they are part of the city. They want a car that somehow expresses who they are and which reflects their personal ideology.”

Conclusion
Although clearly a concept vehicle exploring aspects of future vehicle design, Nuvu nevertheless embodies many messages for today. Its clever interior provides ample headroom, legroom and comfort for most everyday needs without occupying more road space than it needs.

The use of recycled and natural materials underlines Nuvu’s environmental message and while the energy tree might be considered as a piece of whimsy, the use of solar energy is an entirely sensible and practical technological solution to aid an emission free future.

“Nuvu is a concept car, for sure, but it is an entirely credible vehicle,” says Bancon. “It is light, clean and easy to drive. It is practical and a sensible size, yet it is also embodies an element of fun: the future doesn’t look so bad, after all.”
