Poynting Effect, more than one meaning?

[beech]

A thermodynamics book defines Poynting effect--mist in equilibrium above a lake has lower temperature. Work is required to offset the surface tension of the droplets, hence the temperature drops slightly.
On the other hand, internet sources give the Poynting effect as a topic in radio waves.

 

[sokrates]

Poynting Vector is the product of the Electric Field and Magnetic field vector of an electromagnetic wave, which gives the electromagnetic power of the wave at the point it is calculated.

Poynting Effect is related to the analogy you gave. It is a thermodynamical concept.

But I never saw poynting "vector" being mentioned as an effect, so maybe these are not confused very frequently.
