Giant Tesla Coil From 1931
Reported in the Popular Science Monthly way back in 1931
Mr Harvey Wilson with his giant Tesla Coil (Popular Science Monthly 1931)
A Mr Harvey Wilson of Springfield Missouri built himself a huge Tesla Coil so that he could study electricity.
He stated that this machine gave out 32 inch sparks from the electrodes.
Despite the tremendous voltage of these sparks they are deemed harmless to human beings because there is actually a very small amount of actual electric current running through them.
Harvey explains that the electricity hat is needed to run this giant Tesla Coil from the a transformer which in turn is attached to the regular 110-volt circuit that runs the lights in the building.
He made the coil of the transformer by winding 32 miles of wire by hand – can you believe it?
He used a homemade condenser unit which he built using old photographic plates and tinfoil that had been dipped in caster oil.
He also built the rotary spark gap which he uses to interrupt the circuit and the whole contraption is driven by a quarter-horsepower electric motor.
