Copper-based Solar Cells:
Good for the Environment, Good for the Consumer
Copper has long been used in solar heating/hot water systems, where it is commonly used in heat exchangers. Now, it promises to become equally valuable in photovoltaic (PV) systems. These systems produce electricity through the action of sunshine on certain semiconductors, including so-called thin-film materials and the currently most promising material: copper indium gallium diselenide or CIGS.
The Presidential Dollars
Golden Collectibles or the Next Coin of the Realm? The U.S. Mint is betting it’s got it right this time. The Mint placed into circulation the first of its new golden dollar coins featuring, for the initial issue, George Washington.
Copper Helps Control Deadly Prion Protein Infection
Recent studies have shown that the combination of a copper salt with hydrogen peroxide is an effective way of destroying prion proteins on surgical instruments without running the danger of incapacitating the instrument. This is particularly useful in endoscopes that cannot withstand the currently recommended procedure for prion inactivation.
Copper Makes Beer Better: Control of Hydrogen Sulfide in Beer with a Copper Electrolysis System
Hydrogen Sulfide (H2S), a volatile sulfur compound, is a normal byproduct of the fermenting process. But, research has shown that people are very sensitive to the odor of H2S and can detect this odor as an off-flavor at very low concentrations. Researchers have found that the most effective means to control H2S is by using copper which removes the H2S as copper sulfide (CuS) which can then be removed from the final product.
The New Economy
The transition from an industrial to an information-based economy could increase our reliance on copper.
A Case for the Role of Copper Deficiency in "Mad-Cow" Disease and Human Creutzfeldt-Jakob Disease
It has recently been suggested that copper also affects a newly identified class of ailments known as prion diseases, particularly the case for scrapie in sheep, bovine spongiform encephalopathy (BSE, or "mad cow disease") in cattle.
Maitreya Project: Nickel-Aluminum Bronze Selected for World's Largest Statue
