# Will we avoid a mass marine extinction?

This week's Question: In a preliminary report from the International Programme on the State of the Ocean, a scientific panel concluded that ocean degeneration is happening much faster than previously predicted, and that the combination of factors currently distressing the marine environment is contributing to the exact conditions that have been associated with all major extinctions in the Earth's history: an increase of both hypoxia (low oxygen) and anoxia (lack of oxygen that creates "dead zones") in the oceans, warming, and acidification. The researchers warn that the combination of these factors will inevitably cause a mass marine extinction if swift action isn't taken to improve conditions. What do you think? Will we avoid a mass marine extinction?

# Capturing and Using Waste Heat from Cars, Factories, and Power Plants

New technology is being developed at Oregon State University to capture and use the low-to-medium grade waste heat from automobiles, diesel generators, or factories and electrical utilities. The new systems should be able to use much of that waste heat either in cooling or the production of electricity.

# Neutron Analysis Explains Dynamics Behind Thermoelectric Materials

Neutron analysis of the atomic dynamics behind thermal conductivity is helping scientists at the Department of Energy's Oak Ridge National Laboratory (ORNL) gain a deeper understanding of how thermoelectric materials work. The analysis could spur the development of a broader range of products with the capability to transform heat to electricity.

# Geothermal Technology Sequesters Carbon Dioxide Underground

University of Minnesota researchers have developed an innovative approach to tapping heat beneath the Earth’s surface. The method is expected to not only produce renewable electricity far more efficiently than conventional geothermal systems, but also help reduce atmospheric carbon dioxide.

# Will “smart grid” efforts succeed?

The White House announced last week that is was planning to forge ahead with "smart grid" plans for the United States. By increasing controls technology and digital information, the effort would potentially update the American electrical transmission system to provide real-time information about the state of the grid. Supporters of the move say that by monitoring power - where, when and how it's used - consumers and power companies could store power overnight, incorporate intermittent generators like wind and solar, and generally get more bang for their buck. Skeptics, however, mention possible drawbacks in bringing IT to energy, including the security and privacy concerns of consumers whose movements on the grid could be traced and tracked by multiple parties. What do you think? Will "smart grid" efforts succeed? Yes or no?
