Research Method
A patent, a demonstration, and a replicated result answer different questions.
Trace the original wording, identify the energy source, and look for independent measurements before deciding what a result establishes.

Starter Research Threads
Ten questions people already bring to Tesla research.
Topic selection follows recurring current-search themes around Nikola Tesla. It is not a paid keyword-volume report; every claim-heavy thread is labeled so that interest never gets mistaken for evidence.

Tesla 'Free Energy': Patent 685,957, Ambient Sources, and the Evidence Gap
Start with the radiant-energy patent, then distinguish a documented apparatus from modern self-running-device claims. Every proposed build needs measured inputs, outputs, uncertainty, and replication.

Did Tesla Invent Radio? Patents, Priority, and the Legal Record
A precise thread on Tesla's tuned-circuit patents, Marconi's work, and why the radio-origin story deserves a timeline rather than a one-line verdict.

Tesla 3-6-9: Quote Trail, Source Trail, or Modern Numerology?
A claim-audit thread for the popular 3-6-9 attribution. Post the earliest citable source, preserve the wording, and separate documented Tesla material from later numerological interpretations.
