True.

Terman says:
"Radio waves are produced to some extent whenever a wire in open space
carries a high-frequency current."

Kraus says:
"Thus, time-changing current radiates and acceleerated charge radiates."

A joule is a unit of work or energy in the MKS system. A joule is the
quantity of energy needed to transport one coulomb of charge between two
points of one volt potential difference.

Incidentally, "average power" is the kind of power we ordinarily use.

Radio waves as Terman uses above are of the energy which escapes from
the near field of the wire and is unlikekly to be recaptured by the
wire.

It's called "vector addition," not "interaction."

A bit more on the lack of "interaction" between two waves...

A bit more on the "interaction" between two waves...

From "Optics", by Hecht: "Briefly then, optical interference
corresponds to the *interaction* of two or more light waves
yielding a resultant irradiance that deviates from the sum
of the component irradiances." (emphasis mine)

Since the "interaction" between two waves is good enough for
Hecht, it is good enough for me.

Please take your objection up with Eugene Hecht.
