Nikola Tesla's original laboratory was recognized as a historical site in 2018

Nikola Tesla’s biggest dream was a worldwide network of wireless power transmission

He built the Wardenclyffe lab and a massive prototype transmission tower to develop trans-Atlantic transmission, but it was never operational. The concept was based on incorrect assumptions about Earth's conductivity, but it inspired subsequent efforts for wireless systems.

J.P. Morgan provided Nikola Tesla with funding for the Wardenclyffe Tower

The structure was part of a project to transmit electricity and communication signals wirelessly across the globe. Shortly after construction began, Guglielmo Marconi beat Tesla to the punch and transmitted a trans-Atlantic signal, preventing Tesla from getting additional funding to finish his project.

Tesla's lack of business savvy and inability to commercialize led to his obscurity

For decades, despite pioneering technologies for large-scale electrical systems and telecommunications, Nikola Tesla had been forgotten to history. Rather than monetizing his work and becoming more well known, his inventor-first mentality saw him sell off lucrative patents to fund new experiments in the short term.

Nikola Tesla embraced showmanship when promoting ideas ahead of their time

He once electrified himself during a live demonstration to illustrate the safety and power of alternating current, and his presentations often featured arcing coils, glowing lights, and bold claims about a future of wireless power.

The world's first AC hydroelectric power plant incorporated Tesla's engineering

Built at Niagara Falls, New York, the plant alternating current electricity was hailed as the future of power generation. Tesla's fascination with Niagara Falls is traced to his seeing a photo of the waterfalls when he was still a child.

When Tesla died in 1943, the FBI seized his property for national security

Although Nikola Tesla had become increasingly eccentric in his later years, the US government wanted to ensure plans for a possible secret weapon didn’t fall into enemy hands during World War II.

Nikola Tesla was born in modern-day Croatia and moved to the US in 1884

His interest in electricity came from his mother, who invented small household appliances during Tesla's upbringing. Upon arriving in America, he began working for and improving upon the electrical inventions made in Thomas Edison's lab.

A quote by scientist Nikola Tesla

"The scientific man does not aim at an immediate result ... His duty is to lay the foundation for those who are to come, and point the way."

Despite their importance to the functioning of the electric grid, these structures are often considered aesthetically unpleasant. To remedy this, some have been transformed into art installations featuring stained glass and colorful lighting, or built with whimsical designs, such as clown faces or giant bodies.

Take a drone tour of a Tesla factory

The first of Tesla's large-scale European manufacturing plants for its electric vehicles was opened in Berlin in 2022. It—along with other facilities in Nevada, New York, Texas, and Shanghai—collectively manufactures solar panels, batteries, and other energy collection and storage products.

The Bomb-proof, Cold War-era New York data center inspiring spy movies

At 33 Thomas Street in Lower Manhattan, New York City, a 45-story concrete tower with no windows stands imperiously over the city. Inside, 18 floors of telecommunications technology have hummed for decades. The building's purpose—to protect US comms from nuclear fallout—and its design have played into spy movie plotlines. Dive into the building's curious role in pop culture with this long read.

Carbon-neutral data centers may be possible if built within wind turbines

Wind turbine towers are typically hollow, housing only cables and a ladder for maintenance access. The excess electricity a wind turbine collects could power a stack of server racks more than 100 meters (328 feet) high within its tower.

The first rooftop solar panels were installed in 1883

In 1883, New York inventor Charles Fritts created the first solar cell by coating selenium with a thin layer of gold. The cell achieved energy conversion rates of 1 to 2% compared to the 15 to 20% of modern photovoltaics.

Space archaeology studies space trash in the context of heritage and social meaning

Some orbiting objects, such as Elon Musk's Tesla, have symbolic or historical importance, despite being functionally worthless. The oldest human-made object in Earth's orbit is Vanguard 1, a grapefruit-sized satellite launched in 1958. The strangest may be an experimental, inflatable space station containing live cockroaches.

Scientists have diverted the path of lightning using lasers

A proof of concept for a laser protection system, which could be used to protect launchpads and airports in the future, was conducted on the Säntis mountain in northeastern Switzerland. Rapid laser pulses heated air molecules, creating a more conductive, 50-meter (164-foot) path for the electrical discharge to travel through.

Discoveries in electromagnetism became the catalyst for overturning Isaac Newton

To maintain the consistency of experimental results involving electricity, magnetism, and light, time and space had to cease being absolute and could change in value to keep the speed of light constant. This cosmic speed limit forced Einstein to revise the existing model of gravity.

The first lithium-ion battery was invented at ExxonMobil

Initially a side project that became a priority due to the 1973 oil crisis, the battery's flammability risks and manufacturing challenges, along with the waning crisis, led the company to shut down its battery program. Other researchers would gradually improve upon published prototype designs in the next decade.

For decades, the US has considered building a permanent nuclear waste repository

All nuclear waste would have been stored at Nevada's Yucca Mountain, but the Obama administration indefinitely stalled the project after intense community backlash. Spent fuel is now stored at more than 80 locations in 36 states, raising safety concerns.

Why only one of the seven wonders of the ancient world still exists

Greek writers recorded lists of great structures that were later codified by Renaissance writers. The definitive list includes the Colossus of Rhodes, the Giza Pyramid (the only existing one today), the Hanging Gardens of Babylon, the Temple of Artemis at Ephesus, the Statue of Zeus at Olympia, the Mausoleum at Halicarnassus, and the Lighthouse of Alexandria.

The District of Columbia is also featured as the state of origin for the telegraph and Morse code. (Some readers may experience a paywall.)

Potential LIGO sites were selected in pairs, approximately 3,000 kilometers apart

The 1,864-mile distance meant gravitational wave signals would be detected no more than 10 milliseconds apart, ruling out many background signals. The sites needed sufficient plots of nearly flat land, proximity to infrastructure (e.g., electricity), and adequate distance from urban areas and geologically active areas to reduce environmental noise.

Leonard Knight built a folk art landmark in the California badlands

Slab City is an unofficial off-the-grid community on the site of a decommissioned Marine Corps base in the Southern California desert. Knight began constructing his enormous and colorful "Salvation Mountain" in 1984. In 2000, it was designated "a folk art site worthy of preservation and protection."
