Urine: Waste product or future power source?

Researchers in the UK are looking into the use of urine as the ‘fuel’ for microbial fuel cells (MFCs), which use bacterial cultures to break down ‘food’ to create power. MFCs are a developing technology used to power autonomous robots. Science Daily

Farming Kicked Up Dust in West Africa

Dust from the Sahara desert can warm the atmosphere, increase the production of clouds, and prolong drought conditions. Now, researchers have found evidence that intensive farming is responsible for a significant portion of that dust. Experts are cautious, but the connection suggests that factoring in dust production could lead to better global climate models. Science

Heat Waves Could Be Commonplace in the US by 2039

Exceptionally long heat waves and other hot events could become commonplace in the United States in the next 30 years, according to a new study by Stanford University climate scientists. "Those kinds of severe heat events also put enormous stress on major crops like corn, soybean, cotton and wine grapes, causing a significant reduction in yields," said Noah Diffenbaugh, an assistant professor of environmental Earth system science at Stanford and the lead author of the study.

Aerogel: The Future Material of Today

Aerogel, AKA frozen smoke, at first sounds like something out of a science fiction book, but it has been around since 1931. The product was created by Samuel Stephens Kistler in an attempt to replace the liquid in jellies with gas without causing shrinkage. The material is comprised of 90-94% air with the rest made generally of silica (a non-toxic, environmentally-friendly compound), though other common types are from alumina or carbon [Source: CNET]. This allows the gel to not only be good at insulation but also has its use in cleaning oil spills. Jasmine Greene, Care2 News

Along with food, clothing, water, and air, one of the very basic necessities of living ever has been and ever shall be the home.

Take a peek at current technologies and studies that may serve as veritable crystal balls for what may be in store for future construction projects.

Colorful Approach to Solar Energy

An artist's representation shows how a cost-effective solar concentrator could help make existing solar panels more efficient. The dye-based luminescent solar concentrator functions without the use of tracking or cooling systems, greatly reducing the overall cost compared to other concentrator technology. Dye molecules coated on glass absorb sunlight, and reemit it at a different wavelength. The light is trapped and transported within the glass until it is captured by solar cells at the edge. Some light passes through the concentrator, and is absorbed by lower voltage solar cells underneath. [Note: Graphic is not to scale.] National Science Foundation

Rising Currents: Projects for New York’s Waterfront

March 24–October 11, 2010

MoMA and P.S.1 Contemporary Art Center joined forces to address one of the most urgent challenges facing the nation’s largest city: sea-level rise resulting from global climate change. Though the national debate on infrastructure is currently focused on “shovel-ready” projects that will stimulate the economy, we now have an important opportunity to foster new research and fresh thinking about the use of New York City's harbor and coastline. As in past economic recessions, construction has slowed dramatically in New York, and much of the city’s remarkable pool of architectural talent is available to focus on innovation.

An architects-in-residence program at P.S.1 (November 16, 2009–January 8, 2010) brings together five interdisciplinary teams, including Architecture Research Office (ARO), to re-envision the coastlines of New York and New Jersey around New York Harbor and to imagine new ways to occupy the harbor itself with adaptive “soft” infrastructures that are sympathetic to the needs of a sound ecology. These creative solutions are intended to dramatically change our relationship to one of the city’s great open spaces.

This installation presents the proposals developed during the architects-in-residence program, including a wide array of models, drawings, and analytical materials.


Organized by Barry Bergdoll, The Philip Johnson Chief Curator of Architecture and Design. The exhibition is made possible by The Rockefeller Foundation and is the first of five exhibitions in the series Issues in Contemporary Architecture, supported by Andre Singer. Rising Currents @ MoMA
