Hyderabad: 19 December 2021: Have you heard of electric cannons that fire without gunpowder and use the power of a magnet?
In June 1932, the magazine Modern Mechanix reported on the achievements of science, and in fact continued the work of Tesla and the domestic inventor Filippov. "Silent cannons sending their whistling messengers of death into the sky at speeds far in excess of those now attained by gunpowder shells seem likely for the next war, using for motion magnetic fields so powerful that when short-circuited they cause miniature earthquakes."
Promising developments were, expectedly, forgotten and people returned to gunpowder weapons and gasoline and gasoline-powered vehicles.
