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.

Enabling the Future is designing prosthetic appendages modeled more like superhero arms and hands than your average static artificial limbs. And they’re doing it through a website and grassroots movement inspired by two men’s design and creation in 2012 of a metal prosthetic for a child in South Africa.
In order to keep an enterprise truly safe from hackers, cyber security has to go all the way down to the device level. Icon Labs is making the point that security has to be built into device components.
Three days after NASA's MAVEN probe reached Mars, India's Mangalyaan probe went into orbit around the red planet. India's first interplanetary mission, and the first successful Mars probe launched by an Asian nation, has a total project cost of nearly $600 million less than MAVEN's.
