5. Many of Tesla’s inventions were classified.
When Tesla died in 1943, during World War II, the Office of Alien Property took his belongings, Alcorn said. Most of his things were later released to his family, and many ended up in the Tesla Museum in Belgrade, which opened in the 1950s. But some of Tesla’s papers are still classified by the U.S. government.
“I know people have requested things through the Freedom of Information Act, and they are released heavily redacted,” said Alcorn.
As a result of the years of secrecy, many people have speculated about what fantastic inventions might have been suppressed, perhaps to keep them out of enemy hands or, more darkly, to perpetuate the status quo. Perhaps supporting the former theory, Tesla had spoken publically about working on a “death beam.” Those who fear the latter theory often point to his work on harvesting the energy in the forces of nature as something that would upset powerful oil companies.
