Power-hungry supercomputers going green Speed and power have long been the most important criteria when judging a supercomputer's worth as a number-crunching lab workhorse, but energy efficiency is fast catching up. The greenest supercomputers are those that can process the most scientific calculations per second while drawing the least power. [More] rss.sciam.com |
Steven Chu to greenhouse gases: We will bury you The U.S. Secretary of Energy-- channeling former Soviet leader Nikita Khrushchev perhaps?--has one thing to say in this week's Science to the greenhouse gases emitted by coal-fired power plants: We will bury you. Nobel laureate Steven Chu's department has funneled $3.4 billion in stimulus dollars to research and develop the technology known as carbon capture and storage (CCS). [More] rss.sciam.com |
New compound provides a better cage for carbon dioxide Capturing carbon dioxide is simple chemistry. In fact, you may have seen it in your high school chem lab. Remember that tightly sealed bottle of sodium hydroxide, aka lye ? Simply popping the top off that strong base and exposing it to air resulted in a chemical reaction in which the ambient CO2 was absorbed and the lye became sodium carbonate. [More] rss.sciam.com |
