US Navy Secretly Filed Patents for Anti-Gravity Technology Traced to Nazi Bell Weapon

Project Chronos | Hitler's Last Weapon
"Around 2017, the US Navy quietly filed a handful of strange patents. Warping gravity for flight, bending gravity into a weapon, cloaking a craft by spinning charged matter. Every one of those technologies traced back to DLA. This couldn't be a coincidence. There was only one explanation that made sense. The US Navy was building the Nazi bell."
The episode reveals that in 2017-2018, the US Navy filed multiple patents for advanced propulsion technologies including gravity warping, cloaking, and a cone-shaped craft capable of air, water, and space travel. The patents were initially rejected as fiction until the Navy's chief technology officer claimed they worked and that China was developing similar technology. All patents were attributed to aerospace engineer Salvatore Pais, who now works for the US Space Force, and allegedly trace back to Nazi bell weapon technology from World War II.

About this episode

The Y Files host AJ examines claims that Nazi Germany developed an anti-gravity weapon called Die Glocke (the bell) during World War II and traces alleged connections to modern US Navy patents for advanced propulsion technology. The episode explores how ancient Indian king Bhoja wrote about mercury-powered flying machines in 1010 AD but deliberately withheld construction details due to mercury's toxicity. AJ details how the Nazis allegedly attempted to build a bell-shaped device powered by counter-rotating mercury cylinders that could warp time and gravity, though project leader Hans Kammler and the bell itself disappeared at war's end. The episode reveals that NASA engineer Harold Calfman successfully built a mercury-powered ion engine in the 1960s that operated for 11 years on the SERT 2 satellite before the program was abandoned due to mercury poisoning of workers. In 2017-2018, aerospace engineer Salvatore Pais filed multiple US Navy patents for gravity-warping, cloaking, and advanced propulsion technologies allegedly based on spinning charged matter, with the Navy claiming the technology works and that China is pursuing similar capabilities. Most dramatically, the episode exposes how Apollo Fusion, Inc. nearly commercialized mercury-powered satellite engines in 2018 that would have released 20 metric tons of mercury annually into Earth's atmosphere before a UN treaty closed the loophole in 2022. AJ ultimately concludes that while the Nazi bell story lacks solid documentation and likely originated from a single journalist's unverified source, the recurring pattern of mercury-based propulsion attempts throughout history demonstrates humanity's repeated failure to heed ancient warnings about the metal's catastrophic toxicity.
