SCIENCE "KNOCKS OUT" LIGHTNING BOLT

Artificial Lightning

no date

A new experimental lightning-rod "knocks out" enough electricity in less than 1/500 of a second to lift the Woolworth Building off its feet.


Two funnel shaped flashes of fire are all that is left of 132 million volt-amperes.

This lightning-rod is designed to protect overhead transmission lines from the ravages of lightning and is expected to save the country millions of dollars a year.

It makes replacements unnecessary and eliminates the patrolling of lines as well as the building of duplicate lines.

Engineers say that if it had been available ten years ago, the world would have saved over 100 million dollars.
