Tesla Coil Working
An installation representing the working model of Nikola Tesla's Coil Resonant Transformer Circuit, built by Moscow-based "Tesla-FX" group. Lighting bolts appear only on one side due to shortening wires installed for safety reasons; if there were none, the bolts would be omnidirectional from upper torus itself. As the current is of very high frequency, loud siren-like noise is emitted when the device works. Taken with EF 17-40/4L and Sirui T-1205X tripod.
