Explanation from Petr:
The exhibit is an active relaxation and rehabilitation bath with special features that permit the changeability of water volume (0-410 L) and provides a pleasant form of relaxation due to its continual and smooth changes to the ergonomical shape of the structure. The bottom contour of the bath adjusts in order to conform to the required position and height of the user. The various geometrical changes to the shape enables the bath to be “shortened” for example, creating a backing for the legs in order to maximize on comfort.

For the purpose of saving on water consumption, one can simply change the depth of the bath so it becomes shallow or select a shape that is most suitable for the user. The changes to the shape of the bath floor can be modified & readjusted anytime. Another wonderful trait of the bath is that it is equally convenient for bathing children, because one can adjust a safe depth of bath, reducing risk of drowning as well as being equipped with soft finish of the base. In addition to creating minimal dimensions, the bath itself can be used as a baby changing table. Getting in and out of the bath tub is simple and effortless. There’s no need to climb over edges of the bath. This way, it is beneficial for people with physical disability or those completely immobile.

Uniquely, in this bath we can experience an unmissable feeling of soft, rippling of the bath floor during bathing or when having a massage. This is a new form of relaxation which we can daringly refer to as “kinetic therapy”. The type of technology used forms system of 10 pneumatic pistons (compressed air powering pistons) and includes inclinable segments covered with soft upholstery. This lining creates a pleasant feeling without causing pressure on the body even in the case when the bath is low filled or during the filling or draining of the bath tub. The movable segments are covered by special, highly elastic, hygienic and strong foil (used in the concept of BMW Gina. The geometric shape of the head rest can be partially changed and is also made from movable structures, covered in flexible foil. The type of material`s used are synthetic rock (e.g. ceramics, plastic shroud), glass, elastic foil.

Other systems used are classic hydro/air massaging jets capable of being rotated and powered by electric motor. The connection to mains water supply, water outlet, air and hydro massage jet is through flexible hosing. The bottom of the tub is sealed and the whole base can be raised or lowered over a flat surface of the inner side-panels of the bath. That is how water tightness is ensured.

Everything is controlled electronically with a remote control. As a result, it is possible to select filling/draining of the bath, change water temperature, adjust hydro/air massage settings (duration, intensity, cycle program) and change the shape of the bath floor whit comfortably resting in the bath tub. This is done with the help of sensor button on the display of a remote control. The geometry of the bath can be altered simply by means of accessing touch display screen on the remote control. Naturally, the program remembers previous settings and if the conditions allow, the bath immediately fulfills the command of the user. Simultaneously however, whilst making the change, the height of the water surface, its volume and temperature as well as the total water consumption is electronically monitored.

The filling of the bath is possible through water inlets positioned right beneath the head rest, whilst draining is carried out through the segment located in the middle of the bath tub. If we were to come back to the principle of shaping the bath floor, an alternative method exists, which replaces pneumatic pistons and electrically tilted segments with air pouch system (ballonet). In addition, the foil covering the surface of various segments can also be replaced with a variety of other materials available on the market, that have similar properties.

From the website:
Bushbunker represents a concept that has been designed from scratch specifically as a bushfire bunker, and comprehensively engineered to withstand the severe environmental conditions that a major bushfire produces. It has been designed for maximum survivor ability no matter the intensity or type of fire.

A series of two fire doors is used to separate the entrance/storage area from the bunkers main interior to provide a fail safe, and to create an air lock which protects against the infiltration of radiant heat through the first steel fire door. This is an extremely important design feature, as some of the most severe burns to Black Saturday fire survivors were caused by radiant heat.

To outfit the interior, the design makes use of standard off the shelf components such as steel fire doors, steel frames and sealing, bench seating, compressed air cylinders, battery powered electric lighting, storage shelving, water drums, UHF radio and EPIRB, and fire blankets and first aid. This in turn allows for flexibility in the design, and reduces costs.

The Bushbunker has been designed to comfortably accommodate up to 6 adults for an extended period when equipped with compressed air cylinders. These air cylinders also have the additional feature of providing a positive internal air pressure inside the bunker making it impossible for noxious and poisonous outside gasses and smoke to enter.

Hanging above each seating area is a series of refillable standard 20 Litre water containers which provide a gravity fed source of clean water for drinking, cooling and first aid purposes.

Due to its standardized size and modular construction, and depending on the site conditions of a home, the Bushbunker can be specially incorporated into the structure of a house or home, free standing, set into an embankment or partially or totally buried underground.

mPower consists of 2 units: Generation and Collection.

mPower Generation is a plant-shaped human-powered unit that produces electricity for immediate and future use. Users access their account using fingerprint recognition, stand on two pads at the base of the unit, and shift their weight from one pad to the other every ten seconds. The system, developed to take up the least amount of a user’s time and effort, can be adapted for the handicapped. A small portion of the electricity generated is used to power the interactive touch-screen at the top of the unit, which offers a broad range of informational services pre-customised by each user. The remaining majority of the electricity generated is sent to the city’s main power plant, to be used or stored. At their convenience, users receive payment for the electricity they generated by accessing their account at mPower Collection.

mPower Collection is a unit that, using the same fingerprint recognition technology, distributes payment and allows for account customisation to users of mPower Generation.

mPower taps into our greatest natural resource: people. Rather than expending energy to create more, mPower harnesses the excess energy we generate by providing a platform for individuals and companies to create electricity, make money, and improve lives. By offering payment to individuals, including those that are homeless, in exchange for a few minutes of minimal movement via a free-to-use system available to everyone, economic and environmental sustainability and empowerment is made available by involving citizens in generating what has become one of our most essential needs: electricity.

mPower units are established by electric companies. Businesses pay electric companies to advertise on mPower Generation touch-screens; these ads are geared to individuals who previously expressed interest in particular products/services as per information entered upon account set-up, thus negating . This negates the need for expensive market research, PR and advertising campaigns. Electric companies pay consumers for generating electricity via mPower; these payments are competitive with fees paid by consumers for power provided by the same electric companies.

The base of the unit consists of two pads, each mounted on a hydraulic cylinder. The cylinders are connected by a micro-hydro turbine. When a person steps onto one of the pads, the resulting pressure forces fluid from one cylinder into the other, causing it to rise. The more a person repeats the movement of shifting his/her weight from one pad to the other, the more electricity is generated. This system can be replaced with piezoelectric pads or other technologies as appropriate.

In addition to the exercise users get while generating electricity, they can also benefit from services available on Generation’s interactive network, including news, community events, traffic information, public transportation information, calendar, time, date, music, weather, radio, product and service information, mobile device charging, internet, widgets, city maps, games, phone calling services.

mPower fits into our daily activities and ways of life without disrupting them. Generation and Collection units can be placed on, in, or near streets and pavements, public transportation waiting areas, airports and other areas where waiting is involved, parks and community areas, schools and universities, libraries, common areas in apartment blocks, and countless other places.

The concept of mPower can be modified to fit into homes, casinos, gyms, phone booths, internet cafes, and wherever generated energy can be used as direct power or in exchange for services and products such as climate control, public lighting, charging mobile phones and other devices. Other generation methods can also be implemented, such as walking, pedaling and running, see-sawing, swinging, and using body weight/heat. The possibilities are endless, sustainable, and empowering.

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.”

From the designer :

This project started for me in the broad category of personal transportation. Having seen numerous recreational products win previous design competitions, I resolved to develop a product that would not only be ecologically friendly but also offer health benefits to travelers. After some strong consideration it occurred to me that the large majority of unhealthy, polluters in our society were the millions of people sitting in their cars going to and from work every day. Perhaps many of them would like to commute via man-powered vehicle but simply haven’t found the right solution. I immediately set out to try and found what problems people had with the existing products.

It began by keeping the product parameters in as general a terms as possible so as not to limit myself creatively. I then commenced with the researching of existing bicycle commuters to try and understand what they liked and disliked about it. From there I went on to conduct some local surveying of non-bikers. In doing this I learned of several key problems that could be solved through better design. These concerns included lack of storage capacity, poor positioning, and size and bulk of the conveyance. I feel that after hundreds of hours of thought and months of hard work that my proposed solution resolves these issues

I began my design by solving the problem of user posturing. In traditional bike designs the rider’s feet are underneath them causing their torso to hunch forward in order to reach the handles. This results in unnecessary strain on the lower back, arms, and buttocks, not to mention poor aerodynamics. As illustrated I resolved these issues by moving the position of the pedals behind the rider and moving some of the pressure of their body weight onto the front of the hip bones, using a broad front section of the seat and onto their forearms with supports protruding from the handles. The new riding position helped solve the storage problem by freeing up plenty of useable space beneath the rider. In this newly acquired gap I decided to suspend a large bag for cargo. And as for the storage of the bicycle, after the destination has been reached and the cargo contained within the bag has been removed, it can be expanded and the bike can be folded and placed inside.

By trying to promote bicycle commuting this product not only benefits the user by making them happier and healthier but also society as a whole by reducing the amount of automotive emissions.
