In the 1930s they were examined as a means of powering 'atom
smashers'. van de Graff & Co tried Tesla Coils first, moved on to
belt machines later. (I can dig out a scholarly reference. Or
you could....)

[whether they would have is another matter... 8)>>]

Or three different sized receiver coils, and proceed as
above.

Ah. Excellent. (I missed the light bulb on first reading)
May need a 'secondary' (LV) on the receiver to run the light
bulb. Might be enough power to run a small electric motor,
used with a diode, or bridge. (An advantage Tesla lacked...)
Try same receive coil at varying distances.
Try tuning the receive coil.
Measure voltage and current in 'load' and calculate efficiency
from input power.
(I'd guess any One or two of these would serve... just
throwing out ideas....)
