When I was first asked this question one thing came to mind. “Boy, machines sure use a lot of cutting fluids, oils and electricity.” Perhaps these areas that can be improved. That is how I got interested in hydrostatics’ a technique in witch a low viscosity fluid is injected at high pressure on a specially design bearing surface to reduce friction. Hydrostatics have been implemented on hi precision machines such as grinders and wafer slicing machines. But if tuned for friction in less precise machines can they save you energy? Hydrostatics also have the advantage that they do not ware out and do not use oil base lubricants, perhaps there are savings there. And finally upgrading machines with the latest controls and motors which are currently very efficient and can be sized smaller given that you may have lest friction in the system will also help.

Now this merits some research and some number. When I get around to crank this I’ll post it. I will be like carbon footprint equivalent for a CNC machine. And this gets me thinking; maybe it’s not about the net saving but about the intention. All good things start with intentions and there is no telling where this can lead us. Maybe, this can be a key ingredient that can get young people interest in manufacturing; it can become a differentiator.

Any thought on the subject ? What other areas besides machine are there?

Unfortunately, many of us who want to be Green(environmentally protective) really are Green(immature in age or judgment; untrained; inexperienced) when it comes to the impact of our actions. I think the idea of education has to play a huge role in helping us figure out not just how to re-engineer a process to be Green, but why we need to do so.
Fluids are a great start though. It seems like there are so many options that can be pursued to eliminate harmful fluids. I love my job at Slater Tools because we continuously are looking at our Rotary Broaching product, and how to expand the use of this hole cutting tool which uses little to no fluids. My wife Susie works in massage therapy, and the technological changes in fluids is happening there too. Advancements in essential oils have gone from aromatherapy, to supportive care to cancer patients, to who knows?? maybe a cutting fluid replacement some day.
But really, I could look at new ideas to put some Green in my pocket all day long, but it doesn't really help me address the concrete reasons why I need a new idea. I think the more we look at the long term and extended reasons why we do or do not believe something is harmful in manufacturing will really help us advance in the Green initiative. Maybe some oils and electricity are not bad, our bodies are electrical, and there must be something good about oil, I just want to find out more about ... why.

Peter,

One of the reasons I have a lot questions in the piece above is because I know there are lots of questions in on the manufacturing science itself. But what I very certain about is that others are filling in the reasons why we need to move in this direction in all aspects of our lives. I went to collage in the mid 90's to be a "solar engineer" only to find out that most of the literature was written in the 70's and the only interesting engineering challenge in the 90's was solar car racing. After graduation I went into online web marketing (a little programing skill when a long way back then). You could not make a living with green tech in 1999 but that has completely changed today, thanks to many others (including Al Gore) a new generation of people are growing up with a new call to action, 2 of siblings have already started their on green tech companies and that wasn't their original intention in life five years ago.

Now their is a more interesting twist to the use of oil and electricity. If you are running your a business and you have an option to use more or less of a given input, what would you do? To me it is simple economics, once science create the alternative, business will take it, so the pressure is on to provide those options. It's about the money and not necessary "saving trees" for those that see a green movement as something brought back from the hippie movement. If bother to spend the time refining the subject like we have with some many other areas I am confident that we can make substantial improvements.

Talking about educations well "it takes a village" and this the most effective form of village that see us having thus far

I agree wholeheartedly. This is one of those topics I always want to comment about, but feel I lack some meaningful education on, and then I just can't help it. It seems there's never enough time to get totally up to speed. I guess that's life in the village!
