Moontanman Posted June 27, 2011 Posted June 27, 2011 New alloy converts heat directly into electricity By Ben Coxworth The heat given off by electronics, automobile engines, factories and other sources is a potentially huge source of energy, and various technologies are being developed in order to capture that heat, and then convert it into electricity. Thanks to an alloy that was recently developed at the University of Minnesota, however, a step in that process could be saved - the new material is able to convert heat directly into electricity. http://www.gizmag.com/alloy-converts-heat-into-electricity/19025/?utm_source=Gizmag+Subscribers&utm_campaign=8b45e8a4ee-UA-2235360-4&utm_medium=email
swansont Posted June 27, 2011 Posted June 27, 2011 The story is a tad misleading. http://blogs.scienceforums.net/swansont/archives/9049
Moontanman Posted June 27, 2011 Author Posted June 27, 2011 Thanks swansont, i am going to just quit posting news and read your stuff... no just kidding, it was misleading thanks for pointing it out.
John Cuthber Posted June 27, 2011 Posted June 27, 2011 News flash from 1821 http://en.wikipedia.org/wiki/Thomas_Johann_Seebeck discovers thermoelectric effect. Old alloys convert heat to electricity too.
swansont Posted June 27, 2011 Posted June 27, 2011 News flash from 1821 http://en.wikipedia.org/wiki/Thomas_Johann_Seebeck discovers thermoelectric effect. Old alloys convert heat to electricity too. In the journal article they claim that there is some superiority over Seebeck-effect devices, at least under some conditions. e.g. thermoelectrics working better with large temperature differences, but this will work with a small gradient, as long as it incorporates the phase change temperature.
