The Invention Secrecy Act of 1951 is often cited as the "legal black hole" where revolutionary energy and propulsion tech disappears.
How the 1951 Act Works Today
The Act codified the government's power to "gag" any patent that a defense agency deems "detrimental to national security."
The Numbers (as of 2026): There are currently over 6,500 active secrecy orders.
The "John Doe" Orders: These are the most controversial. They are issued to private, independent inventors who have no government funding. If you invent a "zero-point" generator in your garage and file a patent, the USPTO can issue a secrecy order that makes it a federal crime for you to talk about, build, or sell your own invention.
The Penalty: Disclosing an invention under a secrecy order carries a penalty of up to 2 years in prison (or 20 years if it's escalated to espionage charges) and the permanent loss of the patent rights.
The "Energy Suppression" Redline
The most cited evidence for "Tesla-style" suppression comes from a declassified 1971 document (the ASPR 12-Secrecy Order list). It revealed that patents were automatically flagged if they achieved:
Solar Photovoltaics over 20% efficiency (at the time).
Energy Conversion Systems with efficiencies exceeding 70–80%.
The Logic: If an energy source is "too efficient," it is classified as a threat to "economic stability" or "national security," because it could be weaponized or disrupt the global energy infrastructure.
