Revolutionary means of getting power (7)
I believe the answer is:
turbine
This might be a double definition.
'revolutionary means' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'getting power' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for turbine that I've seen before include "Type of engine with internal bladed rotor" , "Power generator" , "Machine or motor for tribune" , "Power-producing motor" , "Rotary motor" .)
