Way to get lift to conserve energy using complex engineering (2-4)
I believe the answer is:
hi-tech
'conserve energy using complex engineering' is the definition.
I can't tell whether this definition defines the answer.
'way to get lift' is the wordplay.
I cannot quite see how this works, but
'way' could be 'e' (Compass direction - East) and 'e' is present in the answer.
'lift' could be 'hitch' (I've seen this before) and 'hitch' is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for hi-tech that I've seen before include "Advanced technology" , "latest devices" , "Sophisticated electronics" , "Using modern construction" , "Style of interior design using features of industrial equipment" .)
