UD study assesses ocean use off Delaware, Maryland and New Jersey coasts

The Center for Carbon-Free Power Integration (CCPI) at the University of Delaware has issued a new report about ocean use off the coast of Delaware and parts of Maryland and New Jersey. The study addresses viable places to locate offshore wind farms, taking into account biological, ecological and other considerations. The report includes feedback from interested groups who attended a November 2011 workshop, as well as input from experts.

“This report demonstrates that the ocean is already active with ecological and human activity,” lead-author Alison Bates said. “It shows what government regulators ought to consider in planning for offshore wind development and the beginning of a way forward for offshore wind developers and existing users to accommodate one another.” (more…)

Solar Cells more Efficient than Photosynthesis – for Now

EAST LANSING, Mich. — In a head-to-head battle of harvesting the sun’s energy, solar cells beat plants, according to a new paper in Science. But scientists think they can even up the playing field, says Michigan State University researcher David Kramer.

Plants are less efficient at capturing the energy in sunlight than solar cells mostly because they have too much evolutionary baggage. Plants have to power a living thing, whereas solar cells only have to send electricity down a wire. This is a big difference because if photosynthesis makes a mistake, it makes toxic byproducts that kill the organism. Photosynthesis has to be conservative to avoid killing the organisms it powers.
