In writing yesterday's post I lost my train of thought and forgot the punchline. Before eating the gelato and searching for ice cream recipe books I had lunch at the Shake Shack, where I enjoyed the a tasty, thick vanilla shake. It was a true dairy overload day! Okay, now on to today's wit and wisdom...
Thanks to a story on Gothamist I visited the Science Barge on Saturday. The Science Barge is a demonstration project of New York Sun Works, a non-profit that promotes "sustainability by building and testing ecologically responsible systems for the production of energy, clean water, and food, and by scientifically observing and measuring human impacts on the local environment."
The barge itself is a sustainable urban farm that is touring the city's waterfront parks over the next couple of years. Power for the barge comes from solar panels, wind turbines and biodiesel and waste vegetable oil. Water comes from captured rain and purified river water. They are hydroponically growing cucumbers (that looked great), tomatoes, peppers, lettuce and basil. A recent addition is a school of tilapia. All that is done with no waste water and no net carbon dioxide emissions.
New York City's population is expected to grow by a million people over the next twenty-five years. All those extra people gotta eat. NY Sun Works, has estimated that the rooftop space in the city is sufficient to grow enough vegetables to meet the city's needs. Whether that is practical is another matter, the point is with a little creativity and ingenuity a lot more food could be sustainably grown within the city.
The Science Barge is docked at Pier 84 (at 44th Street) through June. In July the barge moves to Riverside Park (at 72nd) and then onto Stuyvesant Cove Park (23rd St) in September. Tours are free.

The Science Barge
A project of BrightFarm Systems, the Science Barge is a prototype of a sustainable urban farm built for New York Sun Works in 2007. The 1,300-square-foot greenhouse sits atop a steel barge docked in Yonkers, N.Y. It uses soilless, or hydroponic growing techniques, and is powered by biodiesel, wind and solar energy.

What is the Science Barge?
The Science Barge is a sustainable urban farm powered by solar, wind, and biofuels, and irrigated by rainwater and purified river water.
What does it do?
We grow fruits and vegetables in the city with no carbon emissions, no net water consumption, and no waste stream. The vegetables grown on the Science Barge require seven times less land and four times less water than field crops.
How does it work?
The Barge uses a system called recirculating greenhouse hydroponics. This means that our plants get all of the necessary nutrients through the water, as opposed to getting them through the soil. Arable soil is a very precious resource in our increasingly populated world, and is rarely available in cities; therefore, alternatives must be created to conserve what we have left.
By using only collected rainwater and purified river water to irrigate our crops, the Barge does not tap into water sources that are necessary for providing drinking water, etc. In the greenhouse, this water can be used over and over again, allowing us to use much less than a farm on land.
We are able to produce more fruits and vegetables in less space because our plants are getting all of the nutrients they need directly, so they do not need to spend energy creating intricate root systems as they would in soil. This way, plants can by grown much closer together, and grow much faster.
We power the greenhouse with solar, wind, and biofuels – energy that is carbon neutral, so we’re not contributing to global warming.
Why is this a good idea?
More than half the world’s population now lives in cities. Delivering food to them relies on a transportation system that pollutes the air and water. Conventional farming exhausts fresh water supplies and pollutes streams and rivers with fertilizers. Traditional energy plants contribute to air pollution and global warming. If cities can produce some of their own food, energy, and water then this burden will be lighter. Also, in a changing climate, food security will be compromised in certain parts of the world. Urban agriculture protects people while it protects the environment.
What are you trying to demonstrate?
That growing food in the city is good for the environment and good for people. In a world of climate change, rapid urbanization, and increasing pollution, urban agriculture can help us live more sustainably.
How do you define sustainable?
To us, sustainability means producing what we need without damaging the world around us.
Why should Yonkers care?
Unless we become a more sustainable city, we can expect prices for food and energy to continue to rise, and we can expect traffic congestion and air pollution to get worse. The Barge is a great place to learn about how we can support a more sustainable future.
How are you getting the message across?
We run a very active public education program, with school groups from Westchester, New York City and the greater New York area visiting during the week, and the general public on weekends.
Why a barge?
Although the systems on the Barge were designed for rooftop farms, a touring barge makes us more visible and accessible to the public. A barge is a great place for an urban farm for the same reasons a rooftop is; it receives direct sunlight and more wind for the turbines and can be installed in urban areas.
