Comment on "How to get mechanical work from a capacitor and a couple of batteries" by E.N. Miranda [Rev. Mex. Fís. E 52, 215 (2006)]

R. De Coss-Martínez, C. Valez-Pinzón, R. de Coss


We show that the diagram describing the process to produce mechanical work from the capacitor-batteries system proposed in the reference Rev. Mex. Fís. E 52, 215 (2006) is inconsistent with the analytical results obtained in that paper. Thus, the correct diagram and the process to produce mechanical work are presented.
