RINCON, Josué; AMAYA, Iván  e  CORREA, Rodrigo. ASYMMETRICAL CAPACITOR: EXPERIMENTS AND MODELING. Rev. ing. univ. Medellín [online]. 2012, vol.11, n.20, pp.227-238. ISSN 1692-3324.

This research article describes experiments using several Asymmetrical Capacitors prototypes (AsC) with the objective to reproduce this unusual physical phenomenon, as well as to show its exceptional characteristics. Some results are published for the first time. The operating voltage was increased up to 31kV using a DC generator. The AsC levitated in every experiment, simultaneously generating a gas current from the lowest superficial area electrode. Although this phenomenon has been known for over one century, its scientific basis remains unknown and there isn't a model that properly explains its behavior under different conditions. It was proved that it works as a conventional electrostatic separator because it eliminated solid particles from a gas sample either confined in a container or flowing, with the advantage of low energy requirements. In the same way, at operating conditions, it produces ozone in a controlled way, as in the corona effect.
