On Earth Day this year, the Zaandam cruise ship of the Holland America Line set sail from Vancouver, B.C., with revamped emission technology. In cooperation with several U.S. and Canadian government and regulatory agencies, the cruise line launched a technology demonstration project designed to show the feasibility of using sea water to “scrub” or reduce engine emissions on ocean-going vessels. “This is a ship like no other in the cruise industry,” says Stein Kruse, president and CEO of Holland America Line. “After studies and modifications of the ship’s new test emissions technology, it could dramatically change not only the cruise industry, but the entire maritime industry by reducing ship engine emissions.”
The sea water scrubber system was developed by Krystallon, a subsidiary of BP. It uses the natural chemistry of seawater to remove virtually all sulfur oxide, as well as significantly reduce particulate matter emissions. The sea water is then treated to remove harmful components while the calcium carbonate in seawater renders the sulfur oxides harmless by converting them to sulfates and neutral salts.

In an age of globalization and rapid changes through scientific progress, two of our societies' (and economies') main concerns are to satisfy the needs and wishes of the individual and to save precious resources. Cloud computing caters to both of these.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
