Copper nanowires offer an efficient, inexpensive approach to solar energy harvesting
Copper adorns the Statue of Liberty, makes sturdy, affordable wiring, and helps our bodies absorb iron. Now, researchers at Duke University would like to use copper to transform sunlight and water into a chemical fuel.
Converting solar energy into storable fuel remains one of the greatest challenges of modern chemistry. One of the ways chemists have tried to capture the power of the sun is through water splitting, in which the atoms of H2O are broken apart so the hydrogen may be collected and used as fuel. Plants do this naturally through photosynthesis, and for half a century, scientists have tried to recreate that process by tinkering with chemical catalysts jumpstarted by sunlight.Indium tin oxide (ITO) is one material they’ve commonly tried to use. Researchers prefer it for its transparency—which allows sunlight to pass through and trigger the water-splitting reactions—and its ability to conduct electricity. But ITO is far from an ideal material.”Indium is not very abundant,” said Ben Wiley, assistant professor of chemistry at Duke University. “It is similar in abundance to silver in the earth’s crust.” As a result, solar fuel cells using ITO will likely remain expensive and uncompetitive with conventional energy sources like coal and natural gas, he said.Wiley’s lab has created something they hope can replace ITO: copper nanowires fused in a see-through film.

Subsequent stages One and Two involve NGOs and government officials, so the ZOD stage – the only part of the process which doesn’t have bureaucrats in the room – is an important one.

But this health risk has been covered up ever since, denounces the Foundation. “Health authorities have been careful to exclude ILFN measurement and exposure limits from noise regulations”, said its CEO, Dr. Sarah Laurie. “To this date, they continue to deny any problem exists with ILFN emitted by wind turbines, ignoring complaints of victims and their right to be protected against known health hazards from industrial installations”.




“Global sea level has been rising as a result of global warming, but in 2010 and 2011, sea level actually fell by about a quarter of an inch. Scientists now say they know why: It has to do with extreme weather in Australia. The sea level drop coincided with some of the worst flooding in that continent’s history. Dozens of people died and torrents washed away houses and cars, forcing thousands from their homes. Some of those floodwaters simply ran back into the ocean, so they didn’t affect sea level. But a lot of that water was trapped on the Australian land mass. That’s because the continent has an odd geography.” writes Richard Harris [1] reporting on a work recently published by John Fasullo and others in the paper here commented [2].

In this view “greenhouse gases” function much like a blanket or winter clothing.
