When the Exploratorium science museum in San Francisco relocates next spring to a new $220-million waterside home, visitors no doubt will marvel first at the spectacular views of San Francisco Bay from the building's perch on Piers 15 and 17.

Less noticeable is the network of heating, cooling, water-use and other systems that assist in achieving the goal of net-zero energy use—a lofty target for a major museum.

The new 422,166-sq-ft Exploratorium will be nearly three times larger than the museum's current facility at the landmark Palace of Fine Arts.

The new building also could be the largest net-zero energy museum in the world, according to Nibbi Brothers, San Francisco, the project's general contractor.

TED Talks 400 years after Hudson found New York harbor, Eric Sanderson shares how he made a 3D map of Mannahatta's fascinating pre-city ecology of hills, rivers, wildlife -- accurate down to the block -- when Times Square was a wetland and you...

KC: The Manhattan Project created a picture of the area before the development of a city, the way Henry Hudson did during his 1609 exploration. After 10 years (1999-2009), the research project has expanded to study the entire city of New York. The Welikia Project analyzes geography and landscape ecology to discover the original environment and compare it to present day. Scientists have learned that world's largest cities once had a natural landscape of freshwater wetlands and salt marshes, ponds and streams, forests and fields with an equally diverse wildlife community. By focusing on the city's biodiversity of 400 years ago and the modern era, information can be gathered about what has changed, what has remained constant, where the city was done well and where it needs to improve. This source is useful because it allows for the visualization of NYC in a way never seen before. Urban environments, such as NYC, have a landscape largely created by humans, so the skyscrapers, pavement, and mass population is far removed from the landscape it once was.

TED Talks Western countries throw out nearly half of their food, not because it’s inedible -- but because it doesn’t look appealing. Tristram Stuart delves into the shocking data of wasted food, calling for a more responsible use of global resources.

No one should be surprised that more developed societies are more wasteful societies.  It is not just personal wasting of food at the house and restaurants that are the problem.  Perfectly edible food is thrown out due to size (smaller than standards but perfectly normal), cosmetics (Bananas that are shaped 'funny') and costumer preference (discarded bread crust).  This is an intriguing perpective on our consumptive culture, but it also is helpful in framing issues such as sustainability and human and environmental interactions in a technologically advanced societies that are often removed form the land where the food they eat originates.
