Lies, Damn Lies, and Inextinguishable Lore – EV Fires

Oct 19, 2023

A few weeks ago I was talking to some professional fire fighters and was regaled with EV fire fighting disasters. They told me that EV caught fire all the time, that EV fires were much more dangerous than gasoline fires, and that fire trucks could not carry enough water to put out an EV fire…

HyBlend - Chickens and Eggs in Technology Adoption

I will readily confess that 20 years ago I was not convinced that EV’s were the answer to sustainable energy. Instead, I had long been a fan of hydrogen. I was well aware that there were technical issues associated with hydrogen, but was equally aware that…

For the future of the industry, hire interns, both college and high schoolers. And pay them: none of that silly privileged unpaid intern crap that occurs in non-maritime industries.I generally wait until I receive the printed issue to read Maritime Reporter and Engineering News…

Eye on Maritime Design: Can Wind Propulsion Work by Keeping it Simple?

Eye on Design: The Truth Behind Great Ships

Dec 23, 2021

Last year I provided a list of my favorite historical ships as my contribution to the Great Ships issue. Even though I received some pushback on the list, I see no need to amend it.I created that list to avoid having to judge today’s Great Ships…

Eye on Design: Where Are the Transportation Macro Designers?

Dec 06, 2021

As naval architects and marine engineers we are familiar with the design spiral. While design is not truly a spiral, we use the concept to remind ourselves that all pieces of a ship design interact. The design spiral is not a standard figure and can be simplistic or overcomplicated…
