Discussion Overview

The discussion revolves around the concept of "good efficiency" in products, exploring its definition, relevance, and the various forms of efficiency that exist. Participants question the term's usage and seek clarification on its meaning in different contexts.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant asks for clarification on the term "good efficiency" and its meaning.
  • Another participant suggests that "good efficiency" is not a recognized term and emphasizes that efficiency has many forms and measures.
  • A participant defines efficiency as the ratio of useful output to total input, providing an example with a light bulb, and suggests that "good efficiency" implies improving this ratio towards 100%.
  • One participant requests references to the term "good efficiency," indicating skepticism about its validity.
  • A link is shared to a source discussing efficiency in relation to the Honda Civic hybrid, but the context of "good efficiency" remains unclear.
  • Another participant expresses uncertainty about the term "good efficiency," stating it seems subjective and highlighting the distinction between different types of efficiencies, such as net and gross efficiency.
  • Concerns are raised about the inclusion of reliability or availability in discussions of efficiency.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the term "good efficiency," with multiple competing views regarding its validity and definition. Some participants question its use, while others attempt to define it in relation to general efficiency.

Contextual Notes

There is a lack of clarity regarding the term "good efficiency," with participants noting its subjective nature and the potential for different interpretations based on context. The discussion also highlights the complexity of efficiency as a concept, including various forms and measures.

What is the good efficiency of a product? How do you understand the term "good effiency"?
 
Engineering news on Phys.org
Can you tell us where you have seen the term "good efficiency?" That is not a term used that I know of. You are undoubtedly referring to efficiency, of which there are MANY different forms and measures of efficiency.

If you can, please provide a bit more information on what it is you are looking at.
 
I would say efficiency is quite simply the ratio of useful "stuff" over the total amount " stuff" available.

For example a light bulb has x amount of energy (electrical) available. It uses y amount of energy to produce light, therefore the efficiency is x/y x 100%.

Good efficiency is about improving this ratio towards 100%

Edit: Silly me, it should be y/x * 100%

Honda Civic hybrid? Not very good efficiency[/color]!

:biggrin:

I have never heard of "good efficiency" as a technical term. There is just efficiency, which is readily 'quantifiable'. However, there can be efficiencies of components or systems, and one can talk of 'net' or 'gross' depending on what is incorporated in the formula for efficiency.

"Good efficiency" sounds like a subjective term, where 'good' is simply an adjective.

Then there is the matter of 'reliability' or 'availability'.
