Thoughts on Convoying Fuel Efficiencies

The Maxi Taxi concept describes the advantages of convoying in saving fuel during highway travel. Cars that closely follow each other can achieve impressive reductions in total air drag. Air drag is the leading overall drag component at higher speeds and therefore represents the lion’s share of a car’s fuel consumption at speed. Air drag… Read more »

Project 114 and Student Use.

Project 114 is an innovative approach to engineering computations that is being developed for SNAME by Steve Hollister. In essence, it will be a suit of basic NAME computer programs that run on an Excel input/output backbone. This approach is quite powerful and runs a careful middle ground between large, canned, NAME program suites and home grown NAME computer… Read more »

SWATH, The Art Of Compromise

M&O has worked on both the implementation and the failure analysis on quite a number of SWATH (Small Waterplane Area Twin Hull) projects in the last decades. SWATH vessels hold great promise and continue to intrigue naval architects and potential ship purchasers. When we first became involved in SWATHs, as far back as 1981 with… Read more »

Feedback: Here’s Your Sign.

Life is complicated, and designing to deal with life’s complications is difficult. Unfortunately bad design unnecessarily punishes humanity by increasing inefficiencies and frustrations. Design mistakes get made, and sometimes the mistakes cannot be easily corrected. However, it is difficult to imagine anything more destructive to humanity than bad design that affects many people that can… Read more »

Great Design Is No Joke

True or not, this joke is attributed to Abraham Lincoln: A farmer’s young son comes running into the house. Out of breath he says: “Pa, Pa, the hired hand and Sis are in the hayloft. The hired hand has dropped his pants and Sis has pulled up her skirt! Pa, I think they are fixin’… Read more »

Sprawl, the Infrastructure Trap, and A Real World Solution (Maxi Taxi 9)

A Time magazine article by Leigh Gallagher highlights a problem that we deal with on a daily basis but that pretty much stays just below our awareness horizon. In the article Mr. Gallagher describes a professional epiphany of a town engineer with regard to town planning codes that exhibits itself as suburban sprawl. The issue… Read more »

New Jersey Makes, The World Takes

The actual slogan is “Trenton Makes, the World Takes”, and even in that form it is still a pretty weird slogan. The slogan originated very early in the 20th century when Trenton, NJ just about made anything, and it is supposed to mean: “Trenton makes the stuff that the rest of the world buys”. I… Read more »

NAME Computer Programs In The “I Am Not Dead Yet” Category

As a naval architect and marine engineer I have slowly drifted into a bizarre conundrum that actually may be an industry wide problem that is ripe for an industry wide solution. What I am talking about is a loss of all those really great NAME engineering computer programs that were developed in the 70’s, 80’s… Read more »

Better Ship Electric Arrangements

The SNAME annual meeting is a high speed knowledge exchange fest and the last annual meeting in Seattle may quite possibly have been the best one yet. I always get the printed version of the proceedings and leaf through the papers on the flight home. My proceedings need to be the printed versions because I… Read more »

Is There a New Wind Blowing In Technology? Is It Efficiopunk?

The march of technology is not a straight line. It can take leaps (internet), occasionally stop completely (dark ages), depend on big project steps and raw power (Apollo), or occasionally it seems to do a jitterbug and move all over the place at the same time. When it jitterbugs it seems the world belongs to… Read more »
