So Bozeman to Bakken Oil fields is >400 miles. there and back is >800 miles.
800 miles @ 75MPH is 10h 40min. 800miles @ 85MPH is 9h 24min.

Savings of 1 hour 15 minutes, if you managed to keep average speed close to speed limit, which surprisingly is not horribly hard around that area. I live in South Dakota, and there really is not a problem. Almost no traffic and fairly flat and straight roads.


Fukushima Floating Offshore Wind Turbine Starts Generating Power 181

mdsolar writes in with news about a new wind-energy project off the coast of Fukushima. "A project to harness the power of the wind about 20 kilometers (12 miles) off the coast of Fukushima, site of the March 2011 nuclear disaster, began generating power on an operational basis today. The project, funded by the government and led by Marubeni Corp. (8002), is a symbol of Japan's ambition to commercialize the unproven technology of floating offshore wind power and its plan to turn quake-ravaged Fukushima into a clean energy hub. 'Fukushima is making a stride toward the future step by step,' Yuhei Sato, governor of Fukushima, said today at a ceremony in Fukushima marking the project's initiation. 'Floating offshore wind is a symbol of such a future.'"

Sci-Fi/Fantasy Artist Jean 'Moebius' Giraud Dies At 73 64

Dr Herbert West writes: "According to io9, 'Today is an incredibly sad day for fans of comic books, concept art, and downright anything science fiction. Artist Jean 'Moebius' Giraud, who provided some of the most stunning scifi and fantasy art ever to grace a page, has succumbed to illness at the age of 73.' It's pretty hard to overstate the impact he had on film, comic books, and illustration in general. You can name most any fantasy or science fiction related piece of culture from the last 30 or 40 years, and chances are he provided concept art for it or was involved in some way. Alien, Dune, Heavy Metal, Tron (original AND the new one), The Abyss, Masters of the Universe, The Fifth Element, Willow... the list goes on. With the recent passing of Ralph McQuarrie, it's been a tough week for scifi and fantasy artists."

Book Review: CoffeeScript: Accelerated JavaScript Development Screenshot-sm 100

Michael J. Ross writes "For decades, programmers have written computer code in one language, and then programmatically translated that code into another, lower-level form (typically machine code that can be run directly by a microprocessor, or some sort of bytecode that can be interpreted by a virtual machine). For instance, source code written in C or C++ is compiled and assembled into machine code. In web programming, there are emerging languages and other tools for translating code into JavaScript. For instance, Google Web Toolkit allows the programmer to create web apps in Java. The latest addition to this category is CoffeeScript, a language that can be compiled into JavaScript, and is intended to reduce source code size and clutter by incorporating some of the best operators from other Web scripting languages, particularly Ruby. It is also the topic of a new tutorial, CoffeeScript: Accelerated JavaScript Development." Read on to learn what Michael thinks of this book.

Which is why, when you do use tantalums, you use ones that are specced at twice the voltage you expect over them.

We've used tantalums in some telecom equipment we make, and except for about 5 spectacular failures (explosions, fireballs) on some early prototypes (because of wrong part numbers and such), we've never seen a failure in almost 7 years.

We could not have used electrolytic caps as they would not have survived as long.

BTW: reverse voltage an electrolyte, and witness the explosion (and foul smell) also.... Used to do that to scare people in electronics class.....
Of course, if we redesigned now, I'd probably change out some of the tantalums with ceramic caps.
