Solar-heated bridges, roads
Feb 28, 2010 — In January, we reported on the Solar Roadways project (“Pushing the envelope: Trends in green research and technology,” p. 45), which is working toward using road surfaces as giant...
Spectroscopy detects toxins in veggies
LYON, France – For as long as picky eaters have resorted to hiding vegetables or feeding them to the dog under the table, they also have sought excuses not to eat them. But “They’re icky” doesn’t...
US PV market watch
Feb 28, 2010 — The US financial world was anything but rosy in 2009, with the possible exception of the solar sector. According to a December 2009 market report by GTM Research of Cambridge, Mass., grid-connected photovoltaics (PVs) grew from 320 MW in 2008...
Fad or future: Green market trends
Jan 4, 2010 — Market research indicates that the trend toward sustainability will be growing even a brighter shade of green in the days ahead. One has only to look at the proliferation of LED backlighting in consumer goods, the falling cost and increased...
Flipping the switch: Trends in green applications
Jan 4, 2010 — From stand-alone solar power stations to recycling systems that use machine vision, systems that were futuristic visions not so long ago are real-world applications today. Vis...
Pushing the envelope: Trends in green research and technology
Jan 4, 2010 — Raising efficiency while lowering costs is the trend in solar as well as solid-state lighting. Researchers have been working toward this end in both areas for decades, and there ar...
Stimulating sustainability: Trends in government policy
Jan 4, 2010 — Germany previously was known for its automobile industry. Now it is solar. Not bad for a country with more clouds than sun. The country achieved its title as the world leader in the solar industry largely through its ambitious feed-in tariffs....
Villa Solar Set for June in Madrid
Dec 2, 2009 — At a time when several European countries are proposing cuts to feed-in tariffs, known in the past as a great motivator for the solar industry, cutting-edge research and innovation in sustainable development and renewable energy are ramping up for a...
Big research on tiny technologies
Dec 1, 2009 — IMEC is one busy research center. Headquartered in Leuven, Belgium, the independent research and development center focuses on nanoelectronics and nanotechnology, partnering with companies, universities and other research institutes. One example of...
CT scanner peers into soil and sustainable materials
Dec 1, 2009 — Imagine looking at the inner structure of pretty much anything – and getting ultrahigh-quality, high-resolution images that show it changing over time. Researchers at the University of Nottingham in the UK are doing just that with a...
Nonactive solar materials make a difference
Dec 1, 2009 — In the never-ending quest to lower costs and boost efficiency in solar modules, attention is focused on the active-layer materials such as silicon wafers or copper indium gallium selenide thin films. Nonactive materials, however, can account for...
Peering into a hybrid solar cell
Dec 1, 2009 — Hybrid polymer solar cells are not as common as silicon cells, nor are the efficiencies as high – currently only about 2 percent. But hybrid polymer cells, which are both organic and inorganic, offer two major advantages that keep researchers...
Dual solar sailing projects eye circumnavigation
Nov 1, 2009 — Sailing under wind power has always been green, but two solar boat projects bring the concept to a new level. Both boats are catamarans and plan to circle the globe powered solely by the sun. Currently under construction in Kiel, Germany, is a...
Painting the roof with solar ink
Nov 1, 2009 — Covering rooftops with solar cells came one step closer to reality recently when JA Solar of Yangzhou, China, announced plans to commercialize technology developed by Innovalight, a San Francisco Bay-area company that makes a silicon solar...
Solar dishes popping up in US deserts
Nov 1, 2009 — Next-generation solar dishes called SunCatchers are popping up like desert cactus flowers, with a light and structurally efficient design that can be manufactured on an automotive-type assembly line. The concentrating solar power systems by Stirling...
Venture capital goes green
Nov 1, 2009 — Over the past few decades, venture capitalists have had plenty of waves to ride: computer technology, biotechnology, dot-com technology and nanotechnology. For some of the waves, it was boom or bust – as was the case with the dot-com era – while...
Make green energy, not war
Oct 2, 2009 — A solar farm under construction near the towns of Lieberose and Turnow-Preilack, near Cottbus in Germany’s federal state of Brandenburg, has become the world’s second largest solar power plant– and Germany’s biggest– with the installation of the...
Blue light and carbon capture with MgO
Oct 1, 2009 — Before Jeffrey J. Urban began studies on the concentration, separation and sequestration of carbon, he was greeted with a big surprise. Prior to performing physical characterization, he did “the chemical step,” which, in this case, meant looking at...
Making energy personal
Oct 1, 2009 — A plan sketched out on the back of a paper placemat may one day result in portable, personal power. It all began when Arunas A. Chesonis invited MIT professor Daniel G. Nocera to lunch and asked him what he would do with $10 million from the...
The greening of plastics
Oct 1, 2009 — Plastics have changed the way we live, making possible such items as disposable diapers and lightweight, inexpensive camera lenses. But plastics also can do harm to the environment, especially when their toxic chemicals work their way into the...
US DoE helps flip the switch on LED streetlights
Oct 1, 2009 — Most streetlights in the US are high-pressure sodium, but the many advantages of LEDs are pushing municipalities to make the switch – or at least to think about it. Because it is such a big chunk of change to lay out at the start, the US Department...
Back to green school
Sep 1, 2009 — Renewable energy technologies are everywhere, but nowhere are they more prevalent than on college and university campuses around the globe. Sustainability is the name of the game when it comes to curriculum development, research funding, student...
California community college commitment
Sep 1, 2009 — Butte College of Oroville, Calif., is on a sustainability mission. One goal is to be grid-positive by 2012, and another is to be carbon-neutral by 2015. Well on its way toward achieving those goals, the college recently installed on a campus parking...
Dissolving CIGS for flexible application
Sep 1, 2009 — Solar cell designs traditionally are based on crystalline silicon, but not only has that material been in short supply, the silicon-solar process is relatively expensive. And as the solar industry strives to decrease the cost to make it a viable...
Flexible solar from Canada
Sep 1, 2009 — Small buildings with few electrical demands are prime targets for stand-alone solar power units. That’s the thought behind new solar technology applied to a bus shelter on the campus of McMaster University in Hamilton, Ontario, Canada. The flexible...
