They are mutually exclusive. Tesla's ideas were grounded in real experiments and observations. Kooks live in a fantasy world. Pais is the latter. If you don't have a nose for physics psuedoscience, then ask yourself these questions:

   - Is it an outsider?
   - Is there a conspiracy to explain why their revolutionary ideas are not accepted by mainstream?
   - Do they operate outside of or attack the peer review process?
   - Is there one clear egomaniacal leader with a cult of personality?

There are some truly out there ideas in astrophysics and electromagnetics right now (look up magnetic monopoles, as an example). All the ones worth anything are published in peer reviewed journals.
