The GlidArc I has at least two diverging electrodes immersed in a fast gas flow A high voltage and relatively low current discharge is generated across a gas flow between the electrodes. The discharge forms at the closest point, spreads as it glides along the electrodes, and disappears. Another discharge immediately reforms at the initial spot. The path of the discharge is determined by geometry of the electrodes, flow conditions, and characteristics of the power supply. The discharge performs its own maintenance on the electrodes, preventing chemical corrosion and erosion. The electrodes do not need to be cooled so the energy is directly and totally transferred to the processed gas. The voltage is as high as 20 kV for currents from 0.1 to 5 A per discharge. Multi-discharge systems can be installed easily in large gas lines. 

Any gas or vapor can be directly processed. Droplets, mists, and powders can be present. Gases of any initial temperature are accepted. The pressure drop in the reactor is negligible. In terms of capital and operating costs, the GlidArc-based processes are inexpensive.
