Toward Home-brewed Electricity with "Personalized Solar Energy"

    A rooftop solar panel converts sunlight to electricity. In a new study, an expert describes progress toward an efficient and inexpensive method for storing and distributing solar energy in the home.

New scientific discoveries are moving society toward the era of “personalized solar energy,” in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities. That's the topic of a report by an international expert on solar energy scheduled for the November 2 issue of ACS’ Inorganic Chemistry, a bi-weekly journal. It describes a long-awaited, inexpensive method for solar energy storage that could help power homes and plug-in cars in the future while helping keep the environment clean.

Daniel Nocera explains that the global energy need will double by mid-century and triple by 2100 due to rising standards of living world population growth. Personalized solar energy - the capture and storage of solar energy at the individual or home level - could meet that demand in a sustainable way, especially in poorer areas of the world.

The report describes development of a practical, inexpensive storage system for achieving personalized solar energy. At its heart is an innovative catalyst that splits water molecules into oxygen and hydrogen that become fuel for producing electricity in a fuel cell. The new oxygen-evolving catalyst works like photosynthesis, the method plants use to make energy, producing clean energy from sunlight and water. “Because energy use scales with wealth, point-of-use solar energy will put individuals, in the smallest village in the nonlegacy world and in the largest city of the legacy world, on a more level playing field,” the report states.

Cold and Bubbly: The Sensory Qualities that Best Quench Thirst

New research from the Monell Center finds that oral perceptions of coldness and carbonation help to reduce thirst. The findings could guide sensory approaches to increase fluid intake in populations at risk for dehydration, including the elderly, soldiers, and athletes.

J.R. Macdonald Lab receives nearly $8 million DOE grant renewal

MANHATTAN -- A nearly $8 million grant from the U.S. Department of Energy is supporting the "bread and butter" physics research at Kansas State University's James R. Macdonald Laboratory. The grant is a three-year renewal award, "Structure and Dynamics of Atoms, Ions, Molecules and Surfaces." "This big operational grant is our bread-and-butter," said Itzik Ben-Itzhak, university distinguished professor of physics and director of the J.

New Method for Reporting Solar Data

A straightforward new way to calculate, compile, and graphically present solar radiation measurements in a format that is accessible to decision makers and the general public has been developed by researchers at the University of Texas at Austin and is described in the Journal of Renewable and Sustainable Energy.

Trapped Sunlight Cleans Water

High energy costs are one drawback of making clean water from waste effluents. According to an article in the journal Biomicrofluidics, a new system that combines two different technologies proposes to break down contaminants using the cheapest possible energy source, sunlight.

Report: Policies to Spur Renewable Energy Can Lower Energy Costs

The South could pay less for its electricity in 20 years than is currently projected if strong public policies are enacted to spur renewable energy production and use, according to a report released today by researchers at the Georgia Institute of Technology and Duke University.
