Q & A

What were some of Tesla's eccentric habits and phobias as a child?
-As a child, Tesla developed a number of odd habits and phobias, including an obsession with counting his steps and quantifying the volume of his meals in amounts divisible by three. He also had a strong aversion to women wearing earrings and pearls, disliked the smell of camphor, and was repulsed by the sight of hair.
How did Tesla's childhood traumas impact him?
-The traumatic death of Tesla's older brother Dane when Tesla was a young boy had a profound impact. Tesla felt his father blamed him for the incident and always underappreciated him afterwards. This led Tesla to develop eccentric habits and neuroses as he tried desperately to regain his parents' affection.
What was the 'War of the Currents'?
-The 'War of the Currents' was a rivalry between Thomas Edison, who favored direct current (DC), and Tesla & Westinghouse, who championed alternating current (AC). It took place from 1888-1892, with AC eventually emerging victorious over DC for long-distance power transmission.
How did Tesla envision his World Telegraphy System?
-Tesla envisioned the World Telegraphy System as a pioneering wireless communication network. He described receivers that could print messages, play voice broadcasts, and handheld devices that could decode signals - anticipating modern fax machines, radios, and cell phones.
Why did Tesla fail to achieve many of his visions?
-A key reason was lack of sustained funding and support. After initial backing, investors would often abandon Tesla's projects due to impracticality or failure to quickly generate profits. Tesla was also overly ambitious and did not focus on commercializing his inventions.
What was Tesla's 'death ray' weapon concept?
-In the 1930s, Tesla claimed he was developing a powerful particle beam weapon he called a 'death ray'. It would supposedly shoot concentrated beams of particles to destroy enemy planes and armies. The concept was impractical for the technology of the time.
How did Tesla envision delivering free power?
-Tesla discovered the Earth could conduct electricity without wires. He envisioned large-scale wireless power transmission that would provide electricity freely around the globe. But his backers only wanted profitable inventions.
Why did Tesla become so eccentric in his later years?
-Failure to achieve his visions, lack of funding, legal disputes and descending into poverty all contributed enormously to Tesla becoming increasingly eccentric and reclusive in hotels.
When did Tesla pass away?
-Tesla died alone in Room 3327 of the New Yorker Hotel on January 7, 1943 at the age of 86. Over 2000 people attended his funeral at the Cathedral of St. John the Divine in New York City.
Why is Tesla so admired today?
-Though underappreciated in his time, Tesla's pioneering work with alternating current and wireless technology fundamentally shaped modern electric power systems and telecommunications.

Keywords

💡alternating current (AC)

AC is an electric current that reverses direction periodically. Tesla pioneered the use of AC over direct current (DC) for electricity transmission. He demonstrated that AC was more efficient for long distance transmission than DC, allowing electricity to be transmitted over hundreds of miles. His AC patents were instrumental to the widespread adoption of AC power systems used today.

💡induction motor

An induction motor uses AC power to create a rotating magnetic field that spins the motor. Tesla invented the first induction motor while walking with his friend in a park in 1882, drawing a diagram with a stick. This motor design was key to enabling practical applications of AC power.

💡War of the Currents

The War of the Currents was an intense competition between Tesla & Westinghouse promoting AC and Edison promoting DC for electric power distribution. It took place from 1888-1892 and was won by Tesla and Westinghouse, leading to AC becoming the dominant standard.

💡Tesla coil

A Tesla coil is a type of transformer invented by Tesla that can generate high frequency AC electricity and very high voltages. Tesla used large Tesla coils in his Colorado Springs lab in 1899-1900 to conduct pioneering experiments with wireless power transmission.

💡wireless communication

Tesla made major contributions to the development of wireless communication technologies like radio. In 1893 he demonstrated a remote controlled boat, and his 1897 patent for radio technology was an important milestone.

💡Wardenclyffe Tower

The Wardenclyffe Tower was built from 1901-1905 in Shoreham, NY to be the centerpiece of Tesla’s proposed global wireless transmission system. It was to broadcast information and power wirelessly around the world. But funding ran out before it could become operational.

💡Turbine

From 1909-1913 Tesla worked on developing bladeless turbine designs that he hoped would revolutionize energy production. But he was unable to secure enough investment to develop functional turbines, which contributed to his later financial troubles.

💡Death ray

In the 1930s-1940s Tesla claimed to be developing a powerful particle beam weapon he called a 'death ray' that could shoot down thousands of enemy planes and end war. It attracted lots of media attention but was never fully developed or proven functional.

💡Wireless power

A central focus of Tesla's work was on wireless power transmission - using the Earth to conduct electricity so power could be broadcast across distances without wires. He demonstrated wireless power on a small scale but was unable to achieve his ultimate vision.

💡Eccentric genius

Tesla had many eccentricities and obsessive qualities but also incredible creativity and visionary ideas far ahead of his time. His genius was unevenly recognized during his life but his reputation grew tremendously after his death.
