I am looking for a word that captures the spirit of power-to-weight ratio, but in a mostly non-technical sense.
The spirit I refer to is something like efficiency, productivity, bang-for-buck, or even return on investment, but also perhaps frugality and prudence.
Ideally there will be both noun and adjective forms.
The connotation should be unambiguously positive ("frugal" is too close to "penny-pinching"), and also intrinsically positive, so that additional qualifiers are not needed (for example, "efficiency" must be qualified as either "high efficiency" or "low efficiency").
"Efficiency" and "prudence" together come closest, but is there a single word capturing both?
Example usage in sentences:
- "The word of the new camera tripod makes it attractive for professional fieldwork"
- "Environmentally conscious consumers are increasingly demanding word products that minimize waste without compromising performance"
