How to Transform, with a Capacitor, Thermal Energy into Usable Work
Miranda, E. N.
European Journal of Physics, v31 n6 p1457-1462 Nov 2010
The temperature dependence of the dielectric permittivity is taken into account to study the energy change in a capacitor that follows a cycle between a cold and a hot thermal reservoir. There is a net energy gain in the process that, in principle, can be transformed into usable work. The paper is simple enough as to be used with keen undergraduates who have taken a university general physics or thermodynamics course. Further experimental work and possible technological application are suggested. (Contains 2 figures.)
