The most likely design solutions fall on a scale which ranges from the high speed, low mass rapid transport at one end to the low speed, high mass multi-generation worldship at the other. The medium speed, medium mass cruiser is defined as an intermediate case. Using an energy-based analysis, it is shown that the rapid transport is a less plausible case. The more credible options for human interstellar flight are the multi-generation cruiser and worldship, in either case requiring the construction of an artificial mobile world-like environment for the sustainable support of a town- to city-sized community of travellers. This could be made possible by a shift in the dominant mode of human civilisation from planetary to space-based life. The long-term consequences for interstellar colonisation are illustrated with reference to the percolation theory presented by Geoffrey Landis.<\/p>\n","protected":false},"featured_media":9413,"template":"","meta":[],"pwb-brand":[],"product_brand":[],"product_cat":[56,59,162],"product_tag":[2592,2591,697,2590,804,2593,490,2417],"class_list":["post-9410","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2012papers","product_tag-economic-growth","product_tag-energy-growth","product_tag-interstellar-travel","product_tag-percolation-theory","product_tag-space-colonisation","product_tag-space-technology","product_tag-starship","product_tag-worldship","first","instock","downloadable","virtual","purchasable","product-type-simple","czr-hentry"],"jetpack_sharing_enabled":true,"brands":[],"_links":{"self":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product\/9410","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media\/9413"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=9410"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=9410"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=9410"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=9410"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=9410"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
