Comments Off on American Forests CEO Jad Daley on collaborative forest protection efforts and the tree equity movement

When American Forests was founded in 1875, the United States had no systems for forest governance and management. At the birth of the organization, American Forests pulled together a group of 50,000 people across sectors to establish the first-ever American Forest Congress and the first annual National Arbor Day, which marked the start of the American forest conservation movement. Today, the same coordination and synergistic energy in the United States is needed to bring together the private and public sectors to conserve forests.

NREL’s solar-powered window breaks new ground with 11% efficiency

Comments Off on NREL’s solar-powered window breaks new ground with 11% efficiency

The National Renewable Energy Laboratory (NREL) has revealed its prototype of a solar-powered “smart window,” which has broken new ground by achieving 11 percent efficiency, enough to potentially provide 80 percent of electricity needs in the United States. The NREL smart window is also able to lower building temperatures and generate electricity by changing the window’s appearance from clear to tinted. Not only does this decrease the amount of sunlight entering a building, thus lowering its heat intake, but also turns the windows into photovoltaic panels. Upon shifting to the darker, hazy view, the smart window then starts its energy production . “There is a fundamental tradeoff between a good window and a good solar cell,” said Lance Wheeler , a scientist at NREL. “This technology bypasses that. We have a good solar cell when there’s lots of sunshine and we have a good window when there’s not.” The smart window’s functionality depends upon advanced materials such as perovskite, a calcium titanium oxide mineral that is able to absorb sunlight and generate electricity, and single-walled carbon nanotubes, microscopic structures with incredible strength. While existing solar windows are typically not responsive to changes in sunlight, thus remaining at one set level of transparency, NREL’s prototype breaks new ground by demonstrating a dynamic ability to react to light conditions. Related: New silicon nanoparticles could finally make solar windows commercially viable The window’s ability to transform is made possible by molecules of methylamine, which move in and out of the window depending on the circumstances. When the sun heats up the window, the molecules are absorbed into it, darkening the window. When the sun is not shining directly on the window, the molecules are expelled, which makes the window transparent. In its solar panel form, the smart window has been able to achieve 11 percent efficiency in capturing solar energy and translating it into electricity. The research team at NREL believes that their smart window design could be used to charge mobile devices and on-board electronics such as fans, rain sensors and motors. While research is ongoing, the team is already focusing on how their design could be commercialized and made available to the public. Via Electrek and NREL Images via Dennis Schroeder/NREL and NREL

Comments Off on 19th-century church converted into gorgeous modern lofts in Brooklyn

This 19th-century church in Brooklyn was converted into a modern residential building that lets the original details of the historic structure shine through. The Bushwick church was gutted and turned into a series of daylit lofts available for rent through Nooklyn . Living units are spread over three stories, and they feature beautiful oak floors, antique arched windows, and gold mosaic ceilings. The Victorian Gothic church from the 1890s is located at 618 Bushwick Avenue, Brooklyn. Known as The Saint Marks, the conversion project offers 99 apartments with up to two bedrooms. The units come in different loft -inspired layouts, with large windows and high ceilings , hardwood floors and recessed lighting. Related: A massive London church is transformed into an extraordinary luxury home The developer removed the original spire due to structural instability and zoning rules. They introduced bike storage and onsite parking, central air conditioning in all units. The kitchens feature pale veneer cabinetry and stainless steel appliances. Some of the units, like the one shown in the images, have private decks as well. + Nooklyn Via Uncrate

‘Geomagnetic spike’ 3,000 years ago could offer insight into Earth’s hidden interior

Comments Off on ‘Geomagnetic spike’ 3,000 years ago could offer insight into Earth’s hidden interior

Earth’s magnetic field shields us from damaging radiation from the sun, but its strength and ability to protect us, is variable. Scientists uncovered details about a geomagnetic spike that happened around 1,000 BC that could alter our understanding of the magnetic field and the planet’s interior – and are exploring how a similar event might impact us if it occurred today. Scientists identified 1,000 BC’s geomagnetic spike after investigating copper from slag heaps in Jordan and Israel. They began to explore what Earth’s magnetic field might have been like way back then, and found something surprising: the copper recorded Earth’s magnetic field strength rising and then falling by more than 100 percent in 30 years. Related: Molten jet stream found hurtling through Earth’s core That research was published in 2010 , but University of Leeds lecturer Christopher Davies, in a piece for The Conversation , highlighted other discoveries since pointing to high field strengths around the same time in Turkey, China, and Georgia. Meanwhile, field strengths in Egypt, India, and Cyprus were normal – so the spike may have been only around 2,000 kilometers, or around 1,243 miles, wide. Davies wrote, “Such a rapid change over such a small area marks out the geomagnetic spike as one of the most extreme variations of Earth’s magnetic field ever recorded.” Researchers aren’t quite sure what caused the spike, but the flow of iron in the core could have played a role. That said, explaining the changes that came with the geomagnetic spike requires flows five to 10 times greater than what we observe today. “The prospect that the iron core could flow faster and change more suddenly than previously thought, together with the possibility that even more extreme spike-like events occurred in the past, is challenging some conventional views on the dynamics of Earth’s core,” Davies said. Spikes must be accompanied by weak spots, which is where geomagnetic storms tend to be prevalent. So if a spike happened today, part of the planet could see power outages or satellite disruption because of a geomagnetic storm. But Davies said it’s hard to say if another spike will happen – until recently, the Jordan spike was the only such event scientists had observed. There’s now some evidence a spike also occurred in Texas around 1,000 BC. Via The Conversation Images via NASA Goddard Space Flight Center on Flickr and U.S. Air Force/Staff Sgt. Joshua Garcia

Comments Off on German-French Team Unveils World’s Most Efficient Solar Cell!

A team comprised of the Fraunhofer Institute for Solar Energy Systems , Soitec , CEA-Leti and the Helmholtz Center, Berlin has just unveiled the world’s most efficient solar cell! Boasting an efficiency of 44.7%, the cell breaks the record set by Sharp just three months ago by 0.3%. The four-junction photovoltaic cell is not only dramatically more efficient than the theoretical 33.7% efficiency limit of conventional silicon-based solar PV, but puts the team well on the road to reaching their goal of 50% efficiency by 2015.

Comments Off on NREL Study Finds 32 Acres of Solar Can Power 1,000 Homes

When comparing the advantages and disadvantages of fossil fuels and renewable energy sources, how much real estate each requires to generate electricity is a key factor. While power plants that use coal or natural gas need acres of land to extract natural resources as well as the facility itself, solar can function with surprisingly little. A new report by Energy Department’s National Renewable Energy Laboratory (NREL) has established that only 32 acres is required to power 1,000 homes.
