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.

First Step in Converting Solar Energy Using Artificial Leaf

Two things are needed to produce fuel from sunlight: an antenna that harvests light, and a light-driven catalyst. The most efficient antennae contain bacteria. An international team, headed by Leiden University professor Huub de Groot, modified chlorophyll from an alga so that it resembles the extremely efficient light antennae of bacteria.

Monitoring Plutonium Contamination

Five years from now, scientists will be able to better determine how, when, and why plutonium moves in soil and groundwater. The way to predict how plutonium is transported in groundwater away from a site is by looking at the dominant geochemical processes that control plutonium's (Pu) behavior in the subsurface at environmental levels. But that isn't always so easy.
