Cheap, Efficient, Flexible Solar Cells – From Nanopillars

There's a new way to fabricate efficient solar cells from low-cost and flexible materials. The new design grows optically active semiconductors in arrays of nanoscale pillars - each a single crystal - with dimensions measured in billionths of a meter.

Mercury Rises With Summer Heat

Smog is made up of an array of air pollutants, including mercury. One Ryerson University researcher has found that summer is the peak season for this atmospheric toxin, and that higher levels of mercury species exist in the urban atmosphere as compared to rural regions.

Geothermal Heat Extraction Process Takes Advantage of New Liquid

Scientists at the Department of Energy's Pacific Northwest National Laboratory have come up with an innovative approach that can safely and economically extract and convert heat from untapped geothermal resources. The heat recovery method makes the most of low-temperature “hot rock” resources.

Capturing Carbon Dioxide In A Bowl

The accidental discovery of a bowl-shaped molecule that pulls carbon dioxide out of the air could offer new possibilities for dealing with global warming, including genetically engineering microbes to manufacture these CO2 “catchers.”

Virtually Engineering Energy Conversion Plants

Photovoltaic and wind energy plants, hydroelectric power stations, and biogas plants can be complex to design and maintain. In designing a hydroelectric power station, an engineer needs to know what the pressures, temperatures, and fluid flows will be in the facility. Virtual reality makes planning and operation easier.

NASA Satellite Survey Reveals Dramatic Arctic Sea Ice Thinning

Arctic sea ice thinned dramatically between the winters of 2004 and 2008, with thin seasonal ice replacing thick older ice as the dominant type for the first time on record. The new results, based on data from a NASA Earth-orbiting spacecraft, provide further evidence for the rapid, ongoing transformation of the Arctic's ice cover.

A Low-Cost Manufacturing Solution for CIGS-Based Solar Cells

Though the solar industry today predominately produces solar panels made from crystalline silicon, they remain relatively expensive to make. New players in the solar industry have instead been looking at panels that can harvest energy with CIGS (copper-indium-gallium-selenide) or CIGS-related materials.
