    #30 I agree entirely, Milos, Science and Engineering aren't always just about the "big" stuff, but just as often about understanding and improving the "little" things in life -- like, as you point out, how deep-cycling cell phone batteries reduces their working life.

    #34 Peter> "I'm trying to establish that the term "value engineering" is not a universally understood term.."

    Ah, Peter, if you had only said that at the beginning of your first comment, my eyes would not be glazing over with this exchange.

    To be clear, I agree with you that the term may not have a single universally-accepted definition. But then how many such terms do?

    I believe it sufficient that I used the term in one of its commonly accepted meanings. I am sorry if you mistook what the piece might be about. But it seems to me that the title clearly indicated the article was about "small solutions". Moreover, the lead image reinforces that point, especially in the simulated drawing title box, where it actually describes the object that will be the focus of attention. And if those were not enough to warn you off potential ennui, the first highlighted statement left little doubt.

    "Engineering isn't always simply about the design of a product but just as often about the planning and execution of the building of that product..."

    1. Meaning of “value engineering” in the English Dictionary:
    "The process of reducing the cost of producing a product without reducing its quality or how effective it is:
    Substantial value engineering had to be done to control costs." (http://dictionary.cambridge.org/dictionary/english/value-engineering)

    2. "Value Engineering (VE) is concerned with new products. It is applied during product development. The focus is on reducing costs, improving function or both, by way of teamwork-based product evaluation and analysis. This takes place before any capital is invested in tooling, plant or equipment." - from article: Value Analysis (VA) and Value Engineering (VE): Definitions and Benefits on advice-manufacturing.com (http://www.advice-manufacturing.com/Value-Analysis.html)

    3. "Value Engineering is a systematic analysis method which, when properly applied to a product, process, or service, will reduce costs and increase profit margins. It involves creativity and challenges existing procedures, revealing successful new strategies. It is also known as Value Analysis. The results and techniques are the same." - from McGill University Value Engineering Workshop

    4. "Value engineering can be defined as an organized effort directed at analyzing designed building features, systems, equipment, and material selections for the purpose of achieving essential functions at the lowest life cycle cost consistent with required performance, quality, reliability, and safety." - from the U.S. General Services Administration (GSA) website

    #29 No, @Phil Friedman, I'm not trying to build a straw man. I'm trying to establish that the term "value engineering" is not a universally understood term.

    Rather than being mundane, it's particularly domain-specific. So, for those of us who are not in engineering or government or nautical construction, we're far more likely to impose our own definition than yours. In such a situation, it helps to clarify the intent.

    Your article is technical, and it requires a certain level of knowledge and comprehension. I don't have that and, if I'd known at the outset that it "may be of interest to engineers and tradesman who deal regularly with construction- and manufacturing-related problems and issues," I'd have focused my attentions elsewhere.

    #24 No, Peter, you're not just saying. Your seeking to build a straw man argument by assuming a definition of "value-engineering" that serves your own purposes.

    To wit, a commonly accepted definition of value engineering is, "Value engineering (VE) is a systematic method to improve the "value" of goods or products and services by using an examination of function. Value, as defined, is the ratio of function to cost."

    The particular example I chose here illustrates the performance of a particular operation necessary during the construction of a high-tech military vessel, under a NAVSEA government contract, at a cost far below what was expected or budgeted. Sorry, if that strikes you as too mundane to be of interest, but frankly that is the reaction of a writer who talks about such things, not that of anyone who is a shop-floor veteran, engineer or otherwise. In this context, I am happy to ...

    #24 Just guess Peter, I could write an article on how to fight against hydrogen embrittlement and the environmentally-enhanced cracking of military equipment, including naval ships and fighter. This seems like a very important technological breakthrough, but it is not. Social media is not the ground for such "so-impressive value-engineered solution". Finally, an article like this one by Phil has great practical value and certainly represents a practical and useful example of a successful engineering in a specific field. Science and engineering are not only in national laboratories and large research centers. The work of engineers is also practical. Just my 2 cents.

    Nah, @Phil Friedman, that ain't gonna work.

    I've written about grazillions of "value-engineered solutions" that have nothing to do with any actual engineering. It's one of those, well... marketing phrases intended to make something seem oh-so-impressive.

    It could be about improving operations with new technology that is engineered to simplify interactions, accelerate transactions, and improve productivity because, yes, it's value is engineered-in. Or about a ship whose hull design is so advanced that it slips through water with less drag than a dolphin and, as a result, uses less fuel, increases speed, and reduces onboard manhours, all due to the fact that it's value-engineered.

    I'm just sayin'.

    #8 Thanks, @Todd Jones, for reading and the kind words. Plugs for the intake holes were placed in the female tool by working from the CAD drawings. A male plug placed in a female tool leaves a hole in the molding when it is removed from the tool. Same for the waterjet drives, which were inserted through holes in the transom. We built special purpose alignment jigs for the intake grates which had a vertical spike that extended up into the hull and which had to kiss a laser light beam from a jig on the transom in order for us to know that the waterjet units could be buckled up to the intake ducts/grates.

    A lot of measuring, laser projecting, etc. However, you need to keep in mind that the only really tricky part was to assure that the drive would couple properly to the intake ducts because the engines were coupled to the drives via Cardan shafts (a long jack shaft with a constant velocity universal joint at each end.

    I will tag you, as requested, for subsequent installments of the series. Thanks and cheers!

    #7 Milos, I appreciate the suggestion and already planned to do so -- eventually. What I've discovered, however, is that simultaneously sharing a piece in a number of groups breaks up the "trending" stats among the group notices and tends to retard distribution in the main feed. (LI worships trending and so gives better distribution to what the Algirithm sees as more popular articles.)
    So better to wait for sharing into groups until the initial rush of views and likes is complete and the piece sits on the LI "long tail". Cheers!

    Thank you @Netta Virtanen for sharing this, and to @Juan Imaz for writing this article. Lots of research went into this post!

    I've owned a 2009 and currently drive a 2010 Prius. It has nearly 150,000 miles on it, and still runs like new. The first thing you notice is how quiet hybrid-electric cars are. Many times, I will hear some strange new noise coming from someplace, and then notice it is the car next to me!

    The second thing you notice is the acceleration capability when in "Power Mode." This should be the default setting.

    One thing, and this is a personal opinion, is the decreasing sales of the Toyota Prius. Researchers are attributing some of this to the other vehicles out there, but so far no one has mentioned the aesthetics of the car: It is quite ugly. The "fangs" at the rear are just too - um - radical for me.

    I may switch to the Chevrolet Volt. But the current version looks like a Honda Civic. What's a "green car fan" to do?

    On a more positive note:
    Don't forget the amazing hybrid technology going into the LMP1 (Le Mans Prototype) race cars from Toyota and Porsche and others. Racing always pushes the technology and will eventually find their way into every day (hybrid) cars.

    Thank you @Juan Imaz for sharing your insightful post. Disruptive innovations do not try to bring better products to existing customers in established markets. They should offer a new definition of what’s good, simpler, more convenient, and less expensive products that appeal to new or less demanding customers, but definitely not yet for Hybrid cars (fuel/electricity), even if I drove very sporty ones too. Hydrogen solutions could be more relevant for the next decade, in term of Global Eco Efficiency.
