The increased use of renewable energy sources, particularly sunlight, is highly desirable, as is industrial production that is as CO2-neutral as possible. Both of these wishes could be fulfilled if CO2 could be used as the raw material in a system driven by solar energy. Japanese researchers have now introduced an approach to this type of process.
In a recent issue of Impact Assessment and Project Appraisal, Richard K. Morgan of the University of Otago, New Zealand, reviews the progress of the EIA, with particular emphasis on the last 15-20 years. He also assesses whether EIA is ready for future challenges.
The identified critical threshold for dangerous climate change saying that the increase in global temperature should be below 2 degrees Celsius seems not to have helped the climate negotiations so far. New research shows that negotiations based on such a threshold fail because its value is determined by Nature. Climate negotiators should focus on other collective strategies.
Stony Brook University engineers have won a national award for an innovative energy harvester that has the potential to save millions of dollars in energy costs for railroads while reducing carbon dioxide emissions.
Scientists at The University of Manchester have identified how a plant hormone can affect the rate of cell division in vascular tissue in plants. The findings demonstrate how the hormone controls plant growth to produce more biomass which could be used to make the next generation of biofuels.
Anthropogenic climate change leads to melting glaciers and rising sea level. Between 1902 and 2009, melting glaciers contributed 11 cm to sea level rise. They were therefore the most important cause of sea level rise.
With nearly 25 years experience analyzing energy use in China, the China Energy Group has tailored a variety of resources to help local Chinese officials turn government mandates into practical how-to guides for understanding their energy usage and reducing their carbon dioxide emissions.
The University of British Columbia (UBC) announces the international patent filing for a Battery type Solar/Light conversion cell. This unique generator and storage approach allows both solar power generation and storage within a single cell. Based on photosynthesis, it can be implemented using abundant and readily replenished and renewable biomaterials.
DayStar Technologies, Inc. has entered into a Letter of Intent with Premier Global Holdings Corporation to acquire 100% of its outstanding shares. Premier Global Holdings Corporation has rights to proprietary patent pending Solar conversion unit that is a solar power generation and storage unit within a one unit.
After cellulose, xylan is the most abundant biomass material on Earth, and therefore represents an enormous potential source of stored solar energy for the production of advance biofuels. A major roadblock, however, has been extracting xylan from plant cell walls. Researchers have taken a significant step towards removing this roadblock by identifying a gene in rice plants whose suppression improves both the extraction of xylan and the overall release of the sugars needed to make biofuels.
A new method designed to create expanded construction nodules from mixed plastic waste may replace the expanded clay traditionally used in light concrete that is not used for structural part of a building and often contains air bubbles.
