and essentially demonstrates a method for harvesting the energy of a thermal reservoir through a vibrating sheet of graphene.

>Work can be done while in thermodynamic equilibrium, and a deeper understanding of this will shed light on potential methods for non-equilibrium energy harvesting.

Has this been replicated? Can such a system ever produce a meaningful amount of energy?
