Click on image to enlarge. 14 November 2012—Researchers at the University of Rochester have found an efficient way to produce hydrogen fuel from water using sunlight. A light-powered hydrogen […]
Burning oil is a one-time, irreversible act that leaves nothing of value behind and produces greenhouse gases and pollutants that harm us, Cobb writes. By Kurt Cobb, Guest blogger / November 7, 2012 Kurt Cobb is the author of the peak-oil-themed thriller, ‘Prelude,’ and a columnist for the Paris-based science news site Scitizen. He is a founding member of […]
NEARLY a decade after the adoption of federal renewable fuel standards led to a sharp increase in production of ethanol, some producers in the Corn Belt are considering making a different fuel. The fuel, butyl alcohol, or butanol, is worth more to refiners because it has more energy than ethanol, is easier to handle and more of […]
Ampulse combines low-cost thin-film fabrication with conventional crystalline silicon. PHIL MCKENNA Thursday, March 15, 2012 The cost of solar panels has fallen dramatically in recent years, but it’ll need to drop further still if solar power is to compete with electricity from coal or natural gas. The industry needs to find something cheaper than […]
Crystal Solar’s approach simplifies the manufacturing of silicon wafers and eliminates some expensive equipment. KEVIN BULLIS Tuesday, September 18, 2012 The Korean company Hanwha SolarOne has shown the first commercial-sized solar panel to use a novel technology for producing silicon wafers, which are the most expensive part of a solar cell. Developed by the Santa […]
Despite the business woes of many startups, the technology could have a surprisingly bright future. KEVIN BULLIS Wednesday, October 10, 2012 Cloudy days: Miasole, a leading maker of thin-film solar panels, manufactures its products at its plant in California. PR Newswire When the Chinese energy giant Hanergy decided last week to buy Miasole, a Silicon Valley-based […]
