FIVE MILLION VOLTS
Safe in their observing balcony are these spectators watching man's greatest effort to rival natural lightning.
Five million volts of electric potential is behind this lightning stroke which is shattering an elm log. Over 12,5000,000 kilowatts of electric power were used.
This is power enough to operate over 250 great radio transmitters like the 50 kilowatt stations.
If the current in this lightning stroke were continued for an hour the cost would be more than $5000,000.
