Today as part of my preparations, I watched some training videos.

They&#8217;ve created a <a href=\"http:\/\/www.youtube.com\/MDRShab\">YouTube channel<\/a> where these and future videos will be available.<\/p>\n<p>The first video describes how the GreenHab (water filtration system) works.  <a href=\"http:\/\/en.wikipedia.org\/wiki\/Greywater\">Graywater<\/a> from the shower and sink goes into a series of strainers, and is then piped into a bacteria-filled tank that helps break down phosphates and other bits left over.  From there it goes into a series of three aquatic tanks, with floating plants growing in them, and ultimately the water goes into a reservoir that is used for toilet flushing.<\/p>\n<p><object width=\"425\" height=\"344\"><param name=\"movie\" value=\"http:\/\/www.youtube.com\/v\/oSeQ-bF1yPM&#038;hl=en_US&#038;fs=1&#038;\"><\/param><param name=\"allowFullScreen\" value=\"true\"><\/param><param name=\"allowscriptaccess\" value=\"always\"><\/param><embed src=\"http:\/\/www.youtube.com\/v\/oSeQ-bF1yPM&#038;hl=en_US&#038;fs=1&#038;\" type=\"application\/x-shockwave-flash\" allowscriptaccess=\"always\" allowfullscreen=\"true\" width=\"425\" height=\"344\"><\/embed><\/object><\/p>\n<p>The second video introduces us to the generators (two diesel, one gas) that provide power to the Hab.
