Given all this "loose money" around maybe some could be snagged for SPS's. I think this report in a way is good news. BTW the group's default reply-to address...
Not if they've read Robert Zubrin's *Entering Space*, where there are some very convincing calculations that SPS's beaming power to earth is very unlikely to...
It is good to see discussions about finding a way for SPS's to fit into a market structure. That is where the action is. Zubrin has been great at finding...
SPSs will become a reality, I believe, only after a space elevator gets built. Recent progress in making long chains of carbon nanotubes has raised hopes that...
What's your own analysis of SPS economics? Also, what are the technological and market assumptions behind it? Forgive me if this is not the case: I'm assuming...
"When Zubrin factors in lack of cloudy atmosphere, and the ability to track the sun, together with conversion efficiencies, he calculates an orbital solar...
Terry, If you read my "Science and Society" article, you'll note SPS launched from Earth may compete economically with base power plants (nuclear, coal -...
... plants ... launch ... costs) ... That's easy, I think ... space ... below 0.1 ... As for these two, I don't think that it is possible do both at the same...
I apologize for not including your text in my response, but Yahoo!'s new html formatting makes that somewhat difficult. I find your pessimism about solar...
... Gmail is excellent for managing group mail, and is pretty good at annotated responses like this one. I sent you an invitation email...if you got good spam...
I've decided that the best way to fix this is to take it from the horse's mouth. He goes in W/kg and so does OECD and CRC books, so that's what I'll use. ...
So Zubrin's estimates improved the cost effectiveness of SPS by a factor of 16 in just a few years? I suppose that's encouraging... For current communications...
... No, mine did. ... All indications I have are that launch costs are 40% total cost of launching a commercial satellite, and have been in this ballpark since...
From: solarpowersatelliteplace@yahoogroups.com [mailto:solarpowersatelliteplace@yahoogroups.com] On Behalf Of Terry Wilson Here Mike Combs has not defined a...
... Weren't they using L1? Anyway, having read High Frontier, it is obvious that O'Niell has underestimated targeting, rendezvous and docking difficulties. On...
Somehow my email setting got switched to Daily Digest (again); this has only ever happened with Mark Reiff groups (and twice in less than a month.) I do not...
Hello Group, I have not posted to this group before but, have been watching for about 25 years in a way. In 1982, I went to see Dr. O'Neil (we will miss him)...
I think we are a *very* long way from being able to launch an SPS that's worth doing...like I said in recent posts, we are not going to have a "commercial" SPS...
The launch of an SPS project does not require the launch of a payload. The only thing from starting an SPS project is: 1. A correct business plan. 2. Once that...
As Jimmy Higgins has been wonderfully stirring up some very needed attention on the subject of Solar Power Satellites and related goals, here is an overview...
That's all fine and dandy, but let's be realistic about what can and needs to be done before we seriously discuss any of that. [Non-text portions of this...
... I suppose I can work from that premise ... That is difficult as we are three generations of launch technology and solar power conversion technology away...
No discussion needed on that. I have been and already am discussing these items with the interested parties. What I need from you are the answers to the...
... and solar ... As I said, leave the finance and economics to me. A business plan does not need to show profit. It needs to show a product for a market and...

There are a wide variety of solar concentrator options; suncones is one I hadn't heard of, but may well prove easier. The issue with any concentrator is you...
