The current projected lift capacity of chemical rockets is a million pounds or better. If you need more, you assemble in space.

If jobs, economy, and enviroment can be tied to an aggressive space investment(BTW this is not Mon, 09 Nov 2009 16:42:11 GMT Bert http://tech.groups.yahoo.com/group/space-elevator/message/8997 http://tech.groups.yahoo.com/group/space-elevator/message/8997 Yes but where do you get the funding to build a new system to replace chemical rockets. If we are talking about 100s of billions then the costs are too large Mon, 09 Nov 2009 14:58:10 GMT musthavemorestuff http://tech.groups.yahoo.com/group/space-elevator/message/8996 http://tech.groups.yahoo.com/group/space-elevator/message/8996 I don't agree. I think it will come down to payload sizes. Back in the Apollo days, we hit the limits of chemical rockets. You could not add much more weight Mon, 09 Nov 2009 14:55:54 GMT Bert http://tech.groups.yahoo.com/group/space-elevator/message/8995 http://tech.groups.yahoo.com/group/space-elevator/message/8995 Better yet buy some abandoned oil plateform, and start you own micro nation. The number priorty of this new nation would be to develop cheap access to space Mon, 09 Nov 2009 14:50:21 GMT Jerry Irvine http://tech.groups.yahoo.com/group/space-elevator/message/8994 http://tech.groups.yahoo.com/group/space-elevator/message/8994 Some investments now are done for largely on-economic reasons. Farm Aid, Red Cross, etc. If a space faring company were out there, folks who donate or Mon, 09 Nov 2009 13:35:56 GMT Bert http://tech.groups.yahoo.com/group/space-elevator/message/8993 http://tech.groups.yahoo.com/group/space-elevator/message/8993 I think the odds for forming a political party where development of space as it's main plank has a better chance in succeeding than a publicly traded Mon, 09 Nov 2009 13:26:34 GMT Bert http://tech.groups.yahoo.com/group/space-elevator/message/8992 http://tech.groups.yahoo.com/group/space-elevator/message/8992 2OOB to 500B sounds like a goverment funding to me. The world's largest defense contractor brings in 45B revenues a year. The largest corporation brings in Mon, 09 Nov 2009 13:21:36 GMT Bert http://tech.groups.yahoo.com/group/space-elevator/message/8991 http://tech.groups.yahoo.com/group/space-elevator/message/8991 Agree Nano-molecular manufacturing will be a distributive technology. Once Nanotech becomes pratical all the rules change, Cheers, Bert Mon, 09 Nov 2009 07:14:17 GMT awnd329 http://tech.groups.yahoo.com/group/space-elevator/message/8990 http://tech.groups.yahoo.com/group/space-elevator/message/8990 ... Sure it will, along with many other problems such as that of the cost of anything that is manufactured. As one of the least radical of its many benefits, Mon, 09 Nov 2009 06:40:24 GMT awnd329 http://tech.groups.yahoo.com/group/space-elevator/message/8989 http://tech.groups.yahoo.com/group/space-elevator/message/8989 That would work, but to "slap on" the ribbon you have to get there first. And to take care of more than one piece, you'll have to keep and use up a large Mon, 09 Nov 2009 03:56:24 GMT Scott Orshan http://tech.groups.yahoo.com/group/space-elevator/message/8988 http://tech.groups.yahoo.com/group/space-elevator/message/8988 That's interesting. Now that I've looked into it a little more, I see that electromagnetic drag is a real issue with satellites. I'm not sure if GEO satellites Mon, 09 Nov 2009 02:25:41 GMT Jerry Irvine http://tech.groups.yahoo.com/group/space-elevator/message/8987 http://tech.groups.yahoo.com/group/space-elevator/message/8987 ... I disagree. A public stock offering could raise the funds, and the clear value of the venture would provide sufficient prospective value that the Mon, 09 Nov 2009 02:05:31 GMT Bert http://tech.groups.yahoo.com/group/space-elevator/message/8986 http://tech.groups.yahoo.com/group/space-elevator/message/8986 This sounds like TUI's nanoTerminator System: http://www.tethers.com/nanoTerminator.html Cheers, Bert Mon, 09 Nov 2009 01:44:01 GMT Bert http://tech.groups.yahoo.com/group/space-elevator/message/8985 http://tech.groups.yahoo.com/group/space-elevator/message/8985 Currently CNTs can be produced with tensile strength of 50 Gpa. QC and a process to tie CNTs into a long thread needs to be work out. This is less of a
