    Yes. The second law of thermodynamics applies to the extraction of useful energy (work) from heat energy. It does not apply, for example, to converting electrical energy into work or work into electrical energy. Or from converting kinetic energy into spring potential energy. There is nothing that limits, as a matter of principle, the efficiency of that kind of conversion.
