Perpetuum mobile of the second kind published in a respectable journal:

Electricity generated from ambient heat across a silicon surface, Guoan Tai, Zihan Xu and Jinsong Liu, Appl. Phys. Lett. 103, 163902 (2013). ABSTRACT: "We report generation of electricity from the limitless thermal motion of ions across a two-dimensional (2D) silicon (Si) surface at room temperature. (...) This finding provides a self-charging technology for energy harvesting from ambient heat."

An earlier version of the paper:

http://arxiv.org/pdf/1207.6599
"However,, this finding does not agree with the second law of thermodynamics, which limits the utilization of the random thermal motion of ions to be spontaneously collected to produce electricity. We cannot explain why either this experiment or the previous experiment of graphene did not agree with the traditional theory. More research will be required to fully understand this phenomenon."
