Scrubbing Out Sulfur

Pacific Northwest National Laboratory researchers have developed a reusable organic liquid that can pull harmful gases like carbon dioxide or sulfur dioxide out of industrial emissions from power plants. Power plants could capture double the amount of harmful gases in a way that uses no water, less energy, and saves money.

Cooling Challenge Yields A Better AC Unit

Coolerado Corp. of Denver, CO is the first winner of the UC Davis “Western Cooling Challenge.” Recent federal tests showed that their five-ton commercial rooftop unit should be able to air-condition a typical big-box store with less than half the energy needed by conventional cooling units.

Warming Ocean Triggers Release of Greenhouse Gas

Scientists at the National Oceanography Centre, Southampton, UK, have found that the warming of an Arctic current over the last 30 years has triggered the release of methane - a potent greenhouse gas - from methane hydrate stored in the sediment beneath the seabed.

Energy-Efficient Sewage Plants

High-rate digestion with microfiltration is state-of-the-art in large sewage plants. It effectively removes accumulated sludge, and produces biogas to generate energy. A Fraunhofer Institute study reveals that even smaller plants can benefit from this process.

Absolute Positioning Sensor for Solar Tracking

The T7 absolute inclinometer from US Digital (Vancouver, WA) utilizes a solid-state sensor to give high-accuracy tilt readings over a 360 degree range, and is ideal for concentrated solar power (CSP) and concentrated photovoltaic (CPV) industries.

Using Plastics to Make Solar Cells More Cost-Effective

Scientists are striving to develop organic solar cells that can be produced as easily and inexpensively as thin films. A major obstacle is coaxing these carbon-based materials to reliably form the proper structure at the nanoscale. The goal is to develop cells made from low-cost plastics that will transform at least 10 percent of sunlight into electricity.
