In a worked example, payloads are propelled to a height of 50 km, comparable to the performance of a first-stage rocket. Recent progress in magnetic levitation makes such a system feasible with existing materials. An outline of the economics shows that it can be cost effective, although there are considerable engineering challenges.<\/p>\n","protected":false},"featured_media":7941,"template":"","meta":[],"pwb-brand":[],"product_brand":[],"product_cat":[56,59,155],"product_tag":[1051,1049,1050,958],"class_list":["post-7940","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2005papers","product_tag-evacuated-tube","product_tag-j-knapman","product_tag-magnetic-levitation","product_tag-space-launch","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\/7940","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\/7941"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=7940"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=7940"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=7940"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=7940"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=7940"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
