Instead of a large-diameter (5 to 20 meters) full-scale beanstalk, they propose a 10-20 cm wide ribbon which would be only fractions of a millimeter thick. This is based on a <a href=\"http:\/\/www.niac.usra.edu\/\">NASA Institute for Advanced Concepts<\/a> <a href=\"http:\/\/www.highliftsystems.com\/convertedToHTML\/niac_pdf\/contents.html\">study<\/a>.<br \/>\n<br \/>\nThis design would drive costs down into the $10-billion range &#8211; much less than what AOL\/TimeWarner <a href=\"http:\/\/www.thestar.com\/NASApp\/cs\/ContentServer?pagename=thestar\/Layout\/Article_Type1&#038;c=Article&#038;cid=1035777203790&#038;call_pageid=968350072197&#038;col=969048863851\">lost last year<\/a> &#8211; and allow payloads of a few tons.<br \/>\n<br \/>\nThe ribbon would be 100,000 km long and weigh about 750,000 tons. There&#8217;s a <a href=\"http:\/\/www.highliftsystems.com\/faq.html\">FAQ<\/a> which answers many questions about safety. For instance, the ribbon would wrap 2.5 times around the Equator if it fell down&#8230; but such a thin ribbon would be mostly evaporated during re-entry. <a href=\"http:\/\/www.corante.com\/mooreslore\/20030201.shtml#20319\">Dana Blankenhorn<\/a> elaborates further on problems and opportunities. However, <a href=\"http:\/\/www.cognocentric.blogspot.com\/2003_02_02_cognocentric_archive.html#88527659\">Carey Gage<\/a>, among others, makes the point that such a structure is presently impossible to defend.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Here&#8217;s an update to my previous post about this.
