Haim Dotan Architects helped to design this concentrated solar power flower by Aora, inspired by the shape of a tulip. The first one pictured above was constructed on 0.5acre (2,000sq.m.) of land at Kibbutz Samar. They are now planning on constructing in Spain according to reporting today by Green Prophet.

From the article:

While the plant only produces kilowatts of electrical and thermal energy, and not megawatts like we see at CSP solar plants made by BrightSource or the CSP plant at Kuraymat, Egypt, the idea here is something kind of novel: to create small power plants around or very close to the grid, so that less power is lost along the way, in transmission.

The invention started in the labs of Prof. Jacob Karni at the Weizmann Institute in the 80s.

Each unit would power and heat between 40 and 50 homes by generating 100 kw of electric power and 170kW thermal power.

We’ve written about Fibonacci Series before here on bLAGI. So it does not come as a great surprise to us that the layout of heliostats (solar-tracking mirrors) around a solar power tower could benefit from the natural geometry that informs the physical expression that is manifest by countless of nature’s most beautiful flora, including sunflower, cauliflower, pine cone, cactus, and cabbage.

Thus is the news out of MIT, where researchers have managed to increase the electrical output per square meter of land area around solar power towers like those in operation by Abengoa and Torresol, and the one now under construction by BrightSource.

Above is an idea of what the new arrangement of heliostats will be for solar power towers in the near future (click image to view the source). It seems so obvious doesn’t it? :)

We’re sure that the biomimicry institute would approve.

Happy New Year! We’re kicking off 2012 by launching the latest design competition with $20,000 in total prize award money. Registration is free and you have until July 1, 2012 to submit your design. Here’s a direct link to the official design brief that was just released today: 2012 Design Guidelines

The site is Freshkills Park, New York City’s newest public park. At nearly three times the size of Central Park, what once was the world’s largest landfill will become the City’s largest park. The complete transition will be taking place over the next decades in stages, and the park is designed to be a symbol of sustainable natural ecology within the context of our constructed environment.

Sustainable energy has been included in the conceptual master plan for Freshkills Park from the start. The methane gas that is generated by the landfill below the cap (enough to heat 22,000 homes) is already being sold to a local utility. And the potential for renewable energy generation above the landfill cap is enormous. But this specific context requires special considerations, and the promise of a public park as beautiful amenity creates a unique opportunity to explore creative ways of harnessing natural energy resources.

There have been proposals for wind turbines and solar panels to be installed on the site. But a number of factors may need to be considered before embarking on a standard approach: the proximity to residential neighborhoods, the foundation restrictions of the landfill engineering, the desire to protect the natural environment, birds, and animals, and the promise of Freshkills Park as a place for recreation and enjoyment. We propose that artistic renewable energy installations can provide the perfect answer, by blending utility, beauty, and education, while conforming to the design restrictions of landfill mediation and conserving the local environment.

The monetary prize award to the winners of the 2012 LAGI design competition will not guarantee a commission for construction. LAGI will be working with stakeholders both locally (NYC) and internationally to pursue possibilities for implementation of the most pragmatic and aesthetic of the submitted design proposals.


overview of 2012 competition site boundaries

The site is expansive to allow for maximum creativity. Proposals may cover up to 100 acres and artist teams can choose where to place their design within a 300 acre area (shaded above) that extends over both the North Park and East Park sections of Freshkills Park.

For the 2012 design competition, the Land Art Generator Initiative has also released a modified design brief document specifically for high school students (those age 19 and under) who are interested in submitting their ideas on how to power New York City with art. There will be a $1,000 prize award dedicated to this category.

Education and outreach is a critical part of the LAGI project. We believe in the power of art and creativity to expand public awareness and inspire the future. As a part of LAGI 2012, we will be holding workshop and panel discussion events in New York City during the summer and fall. Please stay tuned here for more information.

Thanks for your interest in the project and we look forward to reviewing all of the amazing submissions in July!

There is some expanded research out of MIT (PDF link) that adds serious weight to the idea that if you install a 3D photovoltaic surface, the increased energy that is generated (when compared to a non-tracking well-oriented flat panel) more than compensates for the added expense of the additional PV material.

This is really great news for renewable energy artists! It means that all of those design ideas that you have about a sculptural form covered in PV may actually be more efficient than a flat panel alternative of the same surface area, despite the fact that some of the PV material in the 3D object will not be operating at peak efficiency throughout portions of the day.

From MIT’s Technology Review:

Marco Bernardi and pals at the Massachusetts Institute of Technology in Cambridge say there is a simple fix that could dramatically increase the performance of photovoltaics. Instead of two dimensional flat panels, Bernadi and co suggest using three dimensional structures.

They’ve simulated the performance of various shapes and tested several of these on the roof of a building at MIT. Their results indicate that 3D structures can increase the amount of energy that can be generated by a given footprint by as much as 20 times. These structures can also double the number of useful peak hours of generation and reduce seasonal variation to boot.

We posted about this idea back in 2009 with a tongue-in-cheek homage to Jean Arp’s 1942 Silencieux. But since then, the 2010 edition of the LAGI design competition has shown the world some truly awe-inspiring examples of what can be done with this revelation to create beautiful and functional objects for our cities.

Windmill Project. Vail 2007

We came across this wonderful renewable energy and land art piece that we’d like to share. It is created by Patrick Marold and was originally inspired by his time in Iceland—the vast landscapes and the long winter nights there. He has since installed the project in various site-specific manifestations in Burlington VT and Vail CO.


Carrying the Windmills to the site. Iceland 2001

From Patrick Marold’s website:

The WINDMILL PROJECT was developed out my desire to map and watch the wind, harnessing its behaviors. While living in Iceland during the long winter nights, I would install this sculptural tool in the pasture and hills. Iceland’s abundance of wind and dark hours provided the perfect setting to develop this idea. The most recent Windmill installation in Burlington, Vermont lasted 14 weeks last fall; and the 2007 installation in Vail, Colorado employed as many as 2700 windmills, covering over 15,000 square feet.

The WINDMILL PROJECT involves placing a mass of light generating windmills in specific outdoor locations. The wind forces each windmill to produce a relevant amount of light, in a sense digitizing the wind. This work of art converts the energy of wind into a responsive visual choreography, exhibiting the rhythm of a mechanical process that is collaborating with the harmony and chaos of wind.


Windmill Project, Town of Vail, 2007. Viewed from frontage road.

There is a video of the installation here. At night, the rotating windmills create a flickering effect on the field of lights, almost like a forest of candles.

Wolt is an interesting and rather artful application of the Humdinger technology to an existing agricultural infrastructure. You can read more about it at the James Dyson Award website where it is listed as an entry along with additional renderings.

From the artist’s description:

‘Wolt’ makes the efficient dual exploitation of modern vineyards possible, by enabling wine and electricity to be harvested. Working on the principle of the ‘Humdinger Windbelt Technology’, it generates electricity by means of a wind-oscillated band instead of using a conventional rotor. The electricity yield exceeds the energy requirements for the wine production and therefore ensures an equable balance of energy within ecological wine growing. ‘Wolt’ is comprised of hundreds of individual elements, which are mounted on to the vineyard posts and linked to each other above ground. This system uses the existing infrastructure of modern vineyards and simply adds more components. ‘Wolt’ has been designed to compete with current wind power production by using cost-saving, economical and robust elements Wine is harvested once a year, but wind energy can be produced throughout the year. ‘Wolt’ therefore offers a lucrative and practical exploitation for wine growing businesses.

We are very honored that Society for Cultural Exchange (the non-profit organization that operates the Land Art Generator Initiative) made the first round selection for the top 25 organizations in the SME/NGO category of the 2011 Zayed Future Energy Prize. Having learned today that SCE did not pass the most recent round of review, we’d like to make mention of our appearance in the first round selection and thank the ZFEP for their consideration of our work towards furthering a beautiful vision of the future of energy. As you can see from the list below, it is a real distinction to have been mentioned in that group of 25 SMEs and NGOs.

Society for Cultural Exchange entered ZFEP 2011 primarily on the merit of the success of the LAGI competition, which has truly inspired the world about aesthetic future energy infrastructure, thanks in large part to the incredible vision of the artist teams who conceived of design entries to the 2010 edition.
