A group of researchers at the City College of New York is developing a new way to generate power for planes and automobiles based on materials known as piezoelectrics, which convert the kinetic energy of motion into electricity. They will present their concept later this month at the 62nd Annual Meeting of the American Physical Society's (APS) Division of Fluid Dynamics will take place from November 22-24 at the Minneapolis Convention Center. http://www.physorg.com/news178114279.html Physics Sun, 22 Nov 2009 12:12:30 EST news178114279 The Naval Research Laboratory's Ion Tiger, a hydrogen-powered fuel cell unmanned air vehicle (UAV), has flown 23 hours and 17 minutes, setting an unofficial flight endurance record for a fuel-cell powered flight. http://www.physorg.com/news174662741.html Technology Tue, 13 Oct 2009 14:27:24 EST news174662741 (PhysOrg.com) -- Diesel and gasoline fuel sources both bring unique assets and liabilities to powering internal combustion engines. But what if an engine could be programmed to harvest the best properties of both fuel sources at once, on the fly, by blending the fuels within the combustion chamber? http://www.physorg.com/news168524276.html Technology Mon, 03 Aug 2009 14:10:02 EST news168524276 Nearly undetectable from the ground, unmanned aerial vehicles (UAVs) are widely used by the military to scan terrain for possible threats and intelligence. Now, fuel cell powered UAVs are taking flight as an Office of Naval Research (ONR)-sponsored program to help tactical decision-makers gather critical information more efficiently... and more quietly. http://www.physorg.com/news159188609.html Technology Fri, 17 Apr 2009 12:04:52 EST news159188609 As the global automobile industry considers alternative energy sources to replace the traditional internal combustion engine, Jessie Pacheco, a mail clerk at Camp Pendleton, has been making his rounds to Marines in General Motors (GM) Chevrolet Equinox fuel cell vehicles (FCVs). The Office of Naval Research (ONR) has sponsored the GM FCVs at Camp Pendleton since 2006 with two more scheduled to arrive later this year. http://www.physorg.com/news156600088.html Technology Wed, 18 Mar 2009 13:02:10 EST news156600088 (PhysOrg.com) -- Shock waves are a well tested phenomenon on a large scale, but scientists at the Argonne National Laboratory and their collaborators from Wayne State University and Cornell University have made a breakthrough that reveals the interaction between shockwaves created by high-pressure supersonic fuel jets. http://www.physorg.com/news156088475.html Physics Thu, 12 Mar 2009 14:55:12 EST news156088475 The EUREKA (Belgium) i-StARS project is developing a compact, fully integrated and low-cost start-stop system for cars to replace conventional alternators in mass production. This second-generation starter alternator reversible system (StARS) is intended to enable the European automotive industry to meet new EU emissions legislation and significantly reduce fuel consumption without needing to redesign the engine. Additionally, it will fulfil global demands for more energy-efficient vehicles. Market forecasts indicate some one million vehicles a year will be using these systems by 2010 with a 4% penetration rate worldwide in the automotive market for such micro-hybrid applications in 2015. http://www.physorg.com/news151241951.html Technology Thu, 15 Jan 2009 11:39:11 EST news151241951 The five engines in Song-Charng Kong's Iowa State University laboratory have come a long way since Karl Benz patented a two-stroke internal combustion engine in 1879. There are fuel injectors and turbochargers and electrical controls. There's more horsepower, better efficiency, cleaner burning and greater reliability. http://www.physorg.com/news140883083.html Technology Wed, 17 Sep 2008 15:11:23 EST news140883083
