Self-Charging Power Cell Converts and Stores Energy

Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. The development eliminates the need to convert mechanical energy to electrical energy for charging a battery.

New Solar Panels Made with More Common Metals Could Be Cheaper and More Sustainable

With enough sunlight falling on home roofs to supply at least half of America's electricity, scientists today described advances toward the less-expensive solar energy technology needed to roof many of those homes with shingles that generate electricity. Their report was part of a symposium on sustainability at the 244th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, being held here this week.

Advances in Decades-Old Dream of Mining Seawater for Uranium

Scientists today reported progress toward a 40-year-old dream of extracting uranium for nuclear power from seawater, which holds at least 4 billion tons of the precious material. They described some of the most promising technology and an economic analysis. Their reports were part of a symposium at the 244th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, being held here through Thursday.

Cleaner Fuel for Cruise Ships and Other Big Vessels From Ingredients in Detergents, Medicines

Scientists today described development of a new fuel mixture to ease the major air pollution and cost problems facing cruise ships, oil tankers and container ships. These vessels tend to burn the cheapest and most highly polluting form of diesel fuel. Their report was part of the 244th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, being held here this week.

Ecologist: Genetically Engineered Algae for Biofuel Pose Potential Risks That Should Be Studied

Algae are high on the genetic engineering agenda as a potential source for biofuel, and they should be subjected to independent studies of any environmental risks that could be linked to cultivating algae for this purpose, two prominent researchers say.

Fueling the Future with Renewable Gasoline and Diesel

A new process for converting municipal waste, algae, corn stalks and similar material to gasoline, diesel and jet fuel is showing the same promise in larger plants as it did in laboratory-scale devices, the developers reported here today. It was part of the 244th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, which continues through Thursday.

New Biorefinery Finds Treasure in Starbucks' Spent Coffee Grounds and Stale Bakery Goods

With 1.3 billion tons of food trashed, dumped in landfills and otherwise wasted around the world every year, scientists today described development and successful laboratory testing of a new "biorefinery" intended to change food waste into a key ingredient for making plastics, laundry detergents and scores of other everyday products. They described the research at the 244th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society.
