Radu Vacarescu has build a Sprain-like electromagnetic motor, using a spiral arrangement of magnets around a rotor, then using an electromagnet to get the rotor past the magnetic stick point. According to his measurements and calculations, he is getting four times more energy out than what is required to push the motor past the stick point. However, the accuracy of his measurements is questioned.
He offers this design as an open source project.
