 There are no passengers on spaceship earth! | The picture includes a quotation from Philosopher Marshall McLuhan: “There are no passengers on spaceship earth. We are all crew”. The picture is a photograph of the quotation included in the exhibition at the Cradle of Humankind in South Africa. Marshall McLuhan was a Canadian philosopher of communication theory. |

The quotation “We are all crew” instills a feeling of unity, so that it is not so much “us and them”, but a sense of “we”. It's not a foreigner polluting the earth, but a fellow crew member!
This webpage, www.efficientpumping.com” offers pumping system design services, and one result is to hopefully increase pumping efficiency, leading to a reduction in energy use, and a potential saving of greenhouse gases. For those crew members on spaceship Earth, this has a positive effect in reducing global warming.
Tomorrow, ask your fellow crew members what they have done, or would like to do, to reduce global warming. But also remember, whether you believe that global warming is a problem, or that it is not important to you, or whether you are a skeptic, is not the only point here. There are also substantial monetary savings to be made from increasing pumping efficiency. For example, pumps that operate away from their best efficiency point may experience not only higher power consumption and energy costs, but cavitation, recirculation and stress from unbalanced forces. These can all lead to increased wear, higher maintenance and unplanned outages which can be costly and inconvenient.
The effect of these problems is reduced when pumps operate closer to their best efficiency point (BEP).
So there are many good reasons to ensure that not only the pumps we use, but the cars we drive, and the machinery we operate all have the best efficiency. After all, on this spaceship, “we are all crew”.
