Windshape

Windshape
Submission to the 2014 Land Art Generator Initiative Copenhagen design competition

Artist Team: Manon Robert, Martin Le Carboulec, Marc Antoine Galup
Artist Location: Seoul, South Korea
Energy Technologies: piezoelectric fabric, rotating electromagnetic generators

Wind speed is transformed into energy with Windshape. The 302 poles, each supporting several piezoelectric textile banners, reshape and transform the site according to the natural wind direction.

As the wind can come from any direction and change quickly, the site will never look the same from one visit to the next. To engage the public in the process, the dimensions of each sail panel are imagined at human scale. Visitors will enjoy getting lost in the changing spaces and observing others as they pass between the sails.

Some sails are intentionally fixed in order to create a passage through the site to the entrance and water taxi terminal. The others are completely free, but can be temporarily fixed by users who would like to modulate the space. These outdoor rooms created by the sail rotations can be both intimate and public.

Several factors inform the design of the sail. The main inspiration was a study of windsurfing sails and their fabrication. A succession of different types of layers on the surface of the sails (aramid fiber scrim and mylar protection) provides tensile strength and protects the piezoelectric fabric layer.

The fabric provides an estimated output power density in the range of 1.10–5.10_W /cm2 at applied wind pressures in the range of 0.02–0.10 MPa. In addition, the dynamo system at the base converts rotational energy with an estimated peak output power of 3.5W. LED lights located in the poles softly illuminate the area at night, making it visible from the opposite shore as a reminder of the power of Copenhagen wind.

Long poles standing on artificial wind slopes continually move like a field of reeds according to the direction of wind. Daylight reflections and dim lighting at night invite visitors to imagine a scene from the Little Mermaid.

Lightfoam is an array of 2,400 polished, white bending poles that harvest the energy of the wind with piezoelectric generators. The 20-meter high poles naturally respond to any change in wind direction. Each is embedded with stacks of piezoelectric discs set between rigid backup plates. To increase the intensity of wind, these piezoelectric structures protrude through a platform shaped to form a valley. The framework of poles is free to bend and respond to all forces, such as wind or people. The more they bend, the more electricity they generate.

At night, LED light sources inside each pole allow the structure to glow or dim depending on the amount of energy they generate. As the wind moves, the fiber rods softly sway to create a dynamic effect and memorable scenery.

The site is transformed into a public park where children can shift or climb between poles, people can ride bicycles, or walk alone along vantage points on the slope. As they are enjoying the park, their activities generate additional energy through the poles and pavements.

As families come together on the playground, this active and energetic atmosphere will influence the surrounding island.

The Place of Tomorrow // Aesthetic Representation of Copenhagen’s Future Plan
Submission to the 2014 Land Art Generator Initiative Copenhagen design competition

Artist Team: Amir Shouri, Fereshteh Tabe
Artist Location: New York City, USA
Energy Technologies: piezoelectric fabric, piezoelectric discs

The Place of Tomorrow is a new type of public garden—a poetic, natural space that demonstrates the future of clean energy.

Oscillating textures of fabric shades are framed in homage to Copenhagen’s future energy-plan. As they wave in the wind, the shades make visible the wind’s forces and aesthetically display the real-time production of electrical energy.

As a reflection of the 8,000 workers who once worked in the Sønder Hoved shipyard, the garden is designed under 8,000 linear fabric shades of different lengths. The energy fabric dances freely in the air, while below park visitors enjoy swimming in the clear blue water. Bicyclers move between lounging couples, enjoying the rippling effects of the sun through the fabric above.

The longer fabric shades produce more electricity and are representative of the future (when most of Denmark’s electricity will be produced by wind), and the shorter shades represent the early 21st century (when only 22% of electricity was produced by wind). Overall, 8,000 pieces of electricity-generating fabric benefit from the movement of electrons in nanowires to produce enough energy to power the LED lights of the project and to offset 900 households on a windy day.

Windbrator

Windbrator
Submission to the 2014 Land Art Generator Initiative Copenhagen design competition

Artist Team: Chanin Sheeranangsu, Pattra Wongsantimeth
Artist Location: Bangkok, Thailand
Energy Technologies: piezoelectric ceramic discs

Windbrator is a work of land art for the regenerative metropolis, providing electricity to the city through the natural force of wind. The key is to generate renewable energy from the vibrations caused by the infinite, yet ever changing, supply of wind.

Kinetic force is captured and turned to electric power by the use of piezoelectric ceramic discs that are arrayed around 220,000 piezoballs—the primary module of the artwork. The structural housing consists of 552 sectional 3-meter square quadrate poles that vary in height from 15–35 meters.

The towers are arranged in a plan to reflect the prevailing wind direction at the site throughout the four seasons. At the center is a serene and monumental public gathering space.

Piezoballs—each 30 centimeters in diameter with a transparent outer skin—adorn the top 10 meters of each pole to harvest electric power. Vibration sensors light up LEDs that function as a seasonal calendar as well as a nighttime spectacle.

This event is free and open to the public!

Driven by the Wind, towards a green horizon
Submission to the 2014 Land Art Generator Initiative Copenhagen design competition

Artist Team: Guido Zeck, Ingrid Ackermans, Peter Twisk
Artist Location: Rotterdam, The Netherlands
Energy Technologies: UGE VisionAIR3™ vertical axis wind turbines

The form of Driven by the Wind is based on the shape of the Sealandia, the first large diesel ship in the world that was built on the site of Burmeister & Wain at Refshaleøen. The design is a reference to the site’s history and a symbol of the path to new horizons.

Its composition of vertical axis wind turbines creates a soft moiré pattern that offers a beautiful fairy-tale background for the Little Mermaid. The dense pattern of turbines allows for a greater efficiency of power production as the turbine rotation is augmented by wind vortices created by the adjacent units. The wind-ship “sails” forward to a green horizon and a clean energy future.

An ecological park is incorporated into the design, with a riverbank rich in biodiversity. The rough vegetation and trees provide an attractive public space, and the ecological design contributes to the spatial experience of the area as a whole.

The ship uses a space frame structure, which supports 750 helical Darrieus-type vertical windmills that have their own inherent beauty. A combined staircase and ramp leads visitors to a recycled wood ship platform on the top of the space frame where they can experience unique views over the city from the 32-meter high bow of the ship.

Wind Decoder
Submission to the 2014 Land Art Generator Initiative Copenhagen design competition

Artist Team: António Pliz, Cláudia Branco
Artist Location: Borba, Portugal
Energy Technologies: aeroelastic flutter (Windbelt™)

The Wind Decoder is a climate-responsive artistic work that promotes an understanding of climate conditions and the technologies available to harvest their energies. The work is similar to a hypercube comprised of three cubes where the outer cube is 30 meters high, and the two inner cubes are 26 meters and 22 meters high.

Old constructions found on the site, including steel and a wooden amphitheatre, give dialectic depth to Wind Decoder’s materials. These physical links contrast old and new materials, such as wood and aluminum. The orthogonal lines of the former industrial facilities help define the new form, evoking memory and connecting the sculpture to the history of the site.

The cubic form is associated with stability and balance—two ambitions for future societies as citizens’ environmental consciousness grows. These ambitions are represented by the outer cube. The slightly rotated and twisted inner cubes represent the wind’s dynamic force, affecting its stability—an analogy to the imbalances of the past. Lights provide a visual representation of the production of wind energy.

The vertical planes are filled with 8200 Humdinger™ Windcell™ panels of 1.0m x 1.0m x 0.05m. Independent Windbelts™ with LED’s will perform the light effect. Despite the main wind streams travelling from west to southwest, the cubic form is designed to react to the movement of the wind from every quadrant.

Aetherius

Aetherius

Artist Team: Marilu Valente
Artist Location: London, UK
Energy Technologies: wind-driven hydraulic cylinder generators

Aetherius expresses the poetic potential of the natural resource of wind, as well as its potential to generate energy. Although wind does not have a shape or color, it can come alive and express its powerful elegance through the use of technology. The intervention aims to transmit the beauty of wind through its material manifestation. Aetherius enables the contemplation of nature as a source of beauty.

The installation moves according to the weather conditions—most specifically to the wind speed, frequency, and direction. The wind direction is not always constant. Even though the prevailing wind is westerly, there is always a microclimate created within an urban context. Aetherius responds to this unpredictability.

Two structures each cover a volume of 40 meters long by 45 meters wide by 30 meters high. The undulating façade is supported by two lateral walls that act as an enclosing architectural feature facilitating the organization of public events, such as concerts and markets.

The wind actuates a series of ultra-light wings attached to a pivot that can rotate within limits, adjusting for possible proximity to visitors. This initiates an interaction between the visitors and the structure.

The top of each wing is linked to a supporting beam with springs that have different levels of elasticity. Therefore each wing moves in a different way than its neighbor wing. This results in an ever-changing façade that responds to surrounding environmental conditions.

100*100*100 WIND TOWER
Submission to the 2014 Land Art Generator Initiative Copenhagen design competition

Artist Team: Mitsuhiro Wada, Takanori Ishii
Artist Location: Brussels, Belgium
Energy Technologies: vertical axis wind turbines

100*100*100 WIND TOWER is a 100-meter cube consisting of a myriad of small windmills that can be seen across the Copenhagen Harbor.

Overlapping frames rise up, giving the appearance of an ordered morning mist. This huge volume is empty at first. It is for the citizens of Denmark to populate the tower with individual contributions of spherical, vertical-axis wind turbines that are available in three sizes: 600 mm, 1200 mm, and 2400 mm. Similar to a crowdsourcing model, a family can contribute a small-size windmill, and a company can purchase a large-size windmill.

This community of turbines will offset the energy use of the individual investors and help Copenhagen achieve its Carbon Neutral 2025 plan. Once the tower is completely filled with turbines, its output will rival that of a conventional wind turbine. By 2025, the tower will contain the maximum number of turbines from the citizens of Copenhagen. The result will symbolize Copenhagen’s commitment to a sustainable future.

Between the double walls of the artwork, a gentle ramp extends from the ground to the summit. An observatory at the top offers a view around the city of Copenhagen. A nighttime glow at the top of the tower represents the amount of electricity produced by the artwork. Days with strong winds will produce a brighter glow than days with faint wind.

The turbines are similar to units developed by Japan Environmental Promotion Association. Because of its small size, Wind Tower can operate with wind speeds as low as 2–6m/s. Its spherical shape enables it to react to the wind from all sides.

Blowing Horn
Submission to the 2014 Land Art Generator Initiative Copenhagen design competition

Artist Team: Hooman Tahvildar Akbary
Artist Location: Tehran, Iran
Energy Technologies: Windbelt™, compact wind acceleration turbine, multi-rotor wind turbine

Near the shores of the great Belt, which is one of the straits that connect the Cattegat with the Baltic, stands an old mansion with thick red walls. I know every stone of it, says the Wind.
-The Story of the Wind, Hans Christian Andersen

This new energy monument is oriented toward the most powerful and prevailing winds on the site. Its form gives reference to the large horns that were used throughout history to call across long distances, but it also serves an important utility. By reducing the cone diameter from the mouth, the speed of the wind increases towards the narrower end of the horn—an application of the compact acceleration turbine lens that makes use of the venture effect.

Inside of Blowing Horn there are a series of wind rotors with a single drive shaft—a multi-rotor wind turbine invented by Doug Selsam. By placing multiple rotors onto a single shaft, the amount of energy that is generated on a single turbine is multiplied.

The ship form at the base of monument is designed to act as a channel, which leads wind through a Windbelt™ array on the deck and the outer shell of this new golden horn for environmental energy production.
