9. The Tesla Death Ray
Inventor Nikola Tesla claimed to have designed a ‘death ray’ capable of shooting down planes from miles away. He referred to this concept as “teleforce,” describing it as a defensive weapon that could project a concentrated beam of particles to destroy approaching aircraft or armies. Despite his assertions, Tesla never built or demonstrated such a device, and it remains a topic of intrigue and speculation. For more on this, see the article “Nikola Tesla’s Towering Ambition” in Smithsonian Magazine: (sciencehistory.org)
