Yes
The kettle will be less efficient because it won't be benefitting from the effects of convection currents. It will use considerably more energy.
Actually, the water inside is heated mainly by conduction. A person nearby is heated by both convection and radiation.
No, voltaic cells (most of what you call "batteries" are actually voltaic cells) work by oxidation and reduction. "Isothermal convection" is a term with which I am unfamiliar that seems like an oxymoron; if everything is the same temperature (isothermal) then convection won't occur, because temperature differences are what drive convection.
If the glider has a roasing chicken inside, it will cause some convection waves, this will lift the Glider up.

Convection. The hot water at the bottom of the pot rises to the top.
Heat transfer from kettle wall is both convection and radiation but convection play the major role on the temperature below 100 oC. Air expand on contact of hot surface and float upward since it is lighter than surrounding air cause stream of air come into contact of the kettle surface result to rapid heat loss.

I learned what convection means in science class.
no it does not.
The only one I can think of off the top of my head, is a kettle boiling water :) Hope this helps! : ) : )
