And that's assuming that recycling would meet 100% of the other needs.<br /><br />I just have a hard time buying into the basic concept that artificial nutrients would suffice for extended periods - or a lifetime.<br /><br />Nothing's perfect.Rob Ghttps://www.blogger.com/profile/06598217971862352016noreply@blogger.comtag:blogger.com,1999:blog-4119159606973297274.post-50990994858333504952010-11-29T10:30:26.601-08:002010-11-29T10:30:26.601-08:00Water would be recycled in space(ships or orbiting...Water would be recycled in space(ships or orbiting habitats). On new planets where water is not immediately available, some form of terraforming would be necessary. There are plenty of simple chemical reactions that will add water to an atmosphere, the most efficient is to bombard the planet with asteroids. The impact frees a lot of carbon, hydrogen, oxygen and nitrogen, just as our own planets early history.<br />As for protein in a closed system like a generation ship, how about yeast cultures? Or vat grown meat products? We are close to developing both now.C Scott Morrishttps://www.blogger.com/profile/17681085967877732728noreply@blogger.com
