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.

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.

Sight

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

Artist Team: Michal Pajakiewicz, Magdalena Rolka
Artist Location: Moscow, Russia
Energy Technologies: piezoelectric generators, photovoltaic thin-film

Sight is installed on the front part of the design site, responding to the unique relationship the location has to its industrial past and the Little Mermaid.

Sight uses the image of the eye as an indicator of the sea level and as a reminder of climate change that will affect us all. The changing environment will affect the visibility of the “eye.” As sea levels rise, the eye will gradually be less visible and will eventually disappear under the water. Until this time, the area will be a wetland—a station for birds and other seacoast species. It will serve the citizens and guests of Copenhagen as a place of rest, relaxation, and meditation.

An angled mirror is constructed on a steel frame. The reflective film is perforated in a form of flaps, equipped with piezoelectric modules. This makes the picture sensitive to weather effects and reduces wind impact by harnessing its energy. On the reverse of the plane is a large photovoltaic array.

Below the angled structure, an image of a child’s eye is constructed pixel-by-pixel with a change of depth from zero to nearly two meters. In the shallow parts, where underwater currents accelerate, the bottom is covered with piezoelectric modules. In deeper parts, the bottom is covered with a local bright stone and local sand. The steep vertical surfaces dividing areas of different depths are reinforced with gabions.

Oscillating Platforms
Submission to the 2014 Land Art Generator Initiative Copenhagen design competition

Artist Team: Felix Cheong
Artist Location: Toronto, Canada
Energy Technologies: wind sails, oscillating water column, Wells turbine

Oscillating Platforms invites the surrounding waterway to enter the site, creating a flooded area within the Sønder Hoved Pier into which a series of freeform, floating platforms are anchored. These platforms, reminiscent of inverse ship hauls, have masts and sails integrated into the design, allowing them to catch the prevailing winds coming from the west. In addition, they are meant to be habitable surfaces that visitors can use as viewing platforms out onto the water.

The platforms act as oscillating water columns that convert both wind and tidal energy into electricity. The design utilizes a modified version of an oscillating water column. The device consists of a pressurized air chamber, which is partially submerged in the water. The energy of the waves and the motion of the platform (resulting from the force of the wind harnessed by the sails, as well as the activity and weight of the occupants) forces captured air through a Wells turbine at the top of the water column. As the water level relative to the platform descends, it draws in air from the exposed top of the water column, also powering the turbine, which rotates in one direction regardless of the direction of airflow.

Oscillating Platforms is playful as well as functional, inviting interaction with people of all ages at any time of the year.



Golden Roots
Submission to the 2014 Land Art Generator Initiative Copenhagen design competition

Artist Team: Ronny Zschörper, Franziska Adler
Artist Location: Münster, Germany
Energy Technologies: biomass, piezoelectric paving

Golden Roots contrasts the urban environment of Copenhagen with the experience of unspoiled nature, suggesting a childhood walk through golden fields of grain. The installation recalls Denmark as a sparsely populated, agrarian country, where its inhabitants maintained a close relationship with nature. A system of paths and bridges guides visitors through a constellation of crop circles, bringing the calm countryside to life in the city.

The experience of being enveloped by nature is achieved through circular fields of rye, which has a natural maximum height of two meters. Red poppies, so familiar in the region, provide a splash of color and biodiversity. The fields are periodically harvested to generate high-energy biomass as well as to provide materials for the construction of observation towers, which change every season. Rye bales coated with potassium silicate are used to create towers of up to 18 meters tall when maximum crop yields are achieved.

Paths and bridges allow visitors to walk within and to rise above the circles of rye. In addition to the energy production through biomass, each crop circle (connected by the paths) contains a piezoelectric floor, transforming the kinetic energy of people into electric energy.

Natalie Mossin and Simone Kongsbak from Smith Innovation in Copenhagen discuss how we can creatively integrate renewable energy into our cities. How can we make new energy-generating interventions that people would like to be a part of and live next door to?

More from Natalie Mossin on Danish renewable energy and the cooperative movement in Denmark:

The overall objective of a sustainable society is, in the end, a collective objective. Taking over ownership of energy production is not an end in itself. It is the taking ownership of the collective solution that is interesting. The initiatives of individuals should be a part of that. The Andelsbevægelsen, or cooperative movement, in Denmark is a really strong part of our culture and it shows beautifully how each individual can take ownership in the collective solution. Each person has a role and influence, but all are acting for the common good.

Natalie Mossin is also head of the Danish Architects’ Association (Arkitektforeningen).

The airplane industry has been a notorious consumer of energy and a large contributor to atmospheric CO2 emissions. The struggle to make this industry more environmentally sustainable has been a daunting task. But current climate concerns have led to the development of amazing solutions to our energy struggle. New innovations in the field are providing remarkable solutions, courtesy of: Saritsu (Smart Intelligent Aircraft Structures) and Solar Impulse.

Modeled from birds’ wings, the wings of Saritsu’s plane have a new “skin”—made from a combination of materials consisting of metals and soft silicone or silicone foam, making the overall plane lighter and “consume even less energy” (Braw 2014). Utilization of these lighter wings on a mass scale could lead to a signifigant decrease in atmospheric CO2 output caused by flying. Saritsu in collaboration with Airbus claims if used largely this technology “would cut 42m tonnes from the world’s annual aeroplane emissions of 705m tonnes” (qtd. by Braw 2014). Or as an additional alternative, a completely solar powered plane could cut emissions altogether.

Solar Impulse has created a completely solar powered plane which “has unlimited endurance” and “can fly for weeks and months without stopping to fuel because it collects its energy from the sun” says Solar Impulse’s co-founder André Borschberg (qtd. by Braw 2014). The solar energy it collects during the day is enough to power it during dark hours as well. Solar Impulse’s planes have already successfully flown for 26 straight hours, and the company plans to fly one of their solar powered planes around the world next year. Though Solar Impulse’s planes are only single-seater planes and will not create a significant impact on the aviation market at the present time, completely altering the aviation business is not Solar Impact’s goal. Rather the company seeks to create an aviation energy ambassador and example of what future airplane energy can look like.

These new aviation technologies are just the beginning of what we will begin to see in the near future. Climate change has necessitated the need for new innovations in the energy sector, and we will be surely floored by what climate change will inspire us to innovate next.
