EarthTechling Solar Power Notches A Victory In Minnesota EarthTechling Still, it said, the “bills passed into law were a good first step in answering Governor Mark Dayton's call to transition to a cleaner energy future that creates thousands of...
A team from Lawrence Livermore National Laboratory claims to have found a method of saline water electrolysis that can both capture CO2 from the atmosphere and use that carbon to neutralize ocean acidification.
Arrays of tree-like nanowires consisting of Si trunks and TiO2 branches facilitate solar water-splitting in a fully integrated artificial photosynthesis system
Lawrence Berkeley National Laboratory (Berkeley Lab) scientists have developed the first fully integrated nanosystem for artificial photosynthesis, in which solar energy is directly converted into chemical fuels.
“Similar to the chloroplasts in green plants that carry out photosynthesis, our artificial photosynthetic system is composed of two semiconductor light absorbers, an interfacial layer for charge transport, and spatially separated co-catalysts,” says Peidong Yang, a chemist with Berkeley Lab’s Materials Sciences Division, who led this research.
“To facilitate solar water- splitting in our system, we synthesized tree-like nanowire heterostructures, consisting of silicon trunks and titanium oxide branches. Visually, arrays of these nanostructures very much resemble an artificial forest.
“In natural photosynthesis, the energy of absorbed sunlight produces energized charge-carriers that execute chemical reactions in separate regions of the chloroplast,” Yang says. “We’ve integrated our nanowire nanoscale heterostructure into a functional system that mimics the integration in chloroplasts and provides a conceptual blueprint for better solar-to-fuel conversion efficiencies in the future.”
The new NASA Sustainability Base was designed by William McDonough + Partners to embody the spirit of NASA while fostering collaboration, supporting health and well-being, and exceed the requirements of LEED® Platinum with systems that will...
Last week, EPA released the fifth drinking water infrastructure needs survey and assessment. This survey indicates that $384 billion is needed to invest in things like pipes, treatment plants and storage tanks to meet the needs of 73,400 water systems across the country over the next 20 years. This huge need represents challenges to delivering safe drinking water to homes and businesses, especially as we face aging infrastructure worldwide.
The New Orleans Bioinnovation Center is a prototype for nimble sustainability, located at a brownfield site in the burgeoning biotechnology district across from Tulane University Medical School on historic Canal Street.
When New Orleans began to rebuild after Hurricane Katrina, NOBIC was back on track, helped by the state, which—like other states—had discovered the economic potential of attracting biotechnology incubators. The goal was to create a collaborative environment in which fledgling start-ups could grow into successful enterprises and spread the wealth.
The glass and steel structure New Orleans Bioinnovation Center strikes a lucid and gracious balance between hard-core sustainability, tenant harmony, and economic viability. Smith believes EDR's success is a result of creating "people ecosystems" by designing for "a long life and a loose fit."

Homes and buildings chilled without air conditioners. Car interiors that don't heat up in the summer sun. Tapping the frigid expanses of outer space to cool the planet. Science fiction, you say? Well, maybe not any more. A team of researchers at Stanford has designed an entirely new form of cooling structure that cools even when the sun is shining. Such a structure could vastly improve the daylight cooling of buildings, cars and other structures by reflecting sunlight back into the chilly vacuum of space.
Interesting article to read on the growth of wave/tidal power in the North Sea. Is this renewable energy source coming into its own in terms of viability and ROI? The debate over the viability and future of wind power in Scotland is omnipresent.
