Ocean energy development with less sound

June 21, 2012 3:48 am | News | Comments

The rise of ocean infrastructure development to tap energy sources such as tides, offshore wind, and natural gas will require more pile driving. But pile driving creates loud, underwater booms that can harm fish and other marine animals. New research indicates that if an individual blow to a pile rises above a particular sound level, fish can be irreparably harmed. This finding has led scientists to recommend the first-ever sound threshold for pile driving based on fish responses.

Cheaper fuel from algae

June 20, 2012 8:11 am | News | Comments

Scientists have revealed an advance toward a long-sought economical process that could turn algae into a sustainable source of biodiesel and other "green" fuels.

Now, a team at Massachusetts Institute of Technology has found a new approach that could reduce the thickness of the silicon used by more than 90% while still maintaining high efficiency.

Green fuel from carbon dioxide and hydrogen?

June 13, 2012 8:19 am | News | Comments

A research team at the Freiburg Materials Research Center in Germany has developed a new system for producing methanol that uses carbon dioxide and hydrogen. The key to helping make their process more efficient is the use of the metal oxides of copper, zinc, and zirconium dioxide as catalysts, enabling the reaction to happen at lower temperatures. Ionic salts may also play a role.

Study: Environmental benefit of biofuels is overestimated

June 10, 2012 12:20 pm | News | Comments

A recent study by two scientists reveals that calculations of greenhouse gas emissions from bioenergy production are neglecting crucial information about carbon dioxide and nitrogen emissions that has led to the overestimation of the benefits of biofuels compared to fossil fuels. They claim the life cycle analysis models of bioenergy production are flawed as a result.
