	How do we know What he 'must' have been referring to.

	cf above.  Did Tesla say:

	Heating is not generally considered a 'photoelectric'

	Or humidity being driven in and out of the frame
	(if wood)
	(which inductors was he using?)
	(or of any of his test equipment.)

	Check NIST papers,  Likely been done.
