CNT Tape Obtains Composite Strength Was As High As 88 GPa
Submitted by hcm1955 on Sun, 03/16/2008 - 16:18.From: http://www.iop.org/EJ/abstract/0957-4484/18/45/455709/
"Abstract. This paper reports on oriented poly(vinyl alcohol)/single-walled carbon nanotube (PVA/SWNT) tapes that were prepared by a mild processing route, involving the use of dimethyl sulfoxide (DMSO) as a solvent. Composite films with homogeneously dispersed SWNTs were cast from solution and drawn into oriented tapes using solid-state drawing. The obtained tapes showed the extraordinary reinforcing effects of the SWNTs, as the addition of 1.0 wt% SWNTs tripled the tensile strength of the PVA tapes. Micromechanical analysis showed that the nanotube contribution to the composite strength was as high as 88 GPa, which is very high when compared to other data reported in the literature, and for the first time begins to exploit the theoretical strength of nanotubes.

NSS Space Elevator Team Needs Volunteers
Submitted by hcm1955 on Sun, 02/17/2008 - 16:18.All,
I am leading a team to compete in this year's Elevator2010 contest. Right now the team consists of seven people. I would like to grow the team to 10 to 20 team members. In particular we need help in laser optics, and embedded controls
If you are interested please shoot me an email.
Cheers,

Cost and Feasibility of Space Elevator
Submitted by hcm1955 on Mon, 02/04/2008 - 03:32.Based on the wikipedia article an orbital ring space elevator would cost 15 Billion in 1980 USD. In today dollars that would be something like 40 to 50 billion dollars.
This is less than 10 % of the estimated cost of the Iraq war. I am neither making a statement for or against the Iraq war, only pointing out the cost compared to other expenses that the US has incurred.
A space elevator design based on orbital rings is well within the capability of today's science and engineering skills. I believe the major obstacle in designing and building a space elevator is lack of political will, not technical limitations.

BALI, Indonesia - While great nations fretted over coal, oil and global warming, one of the smallest at the U.N. climate conference was looking toward the heavens for its energy.
The annual meeting's corridors can be a sounding board for unlikely "solutions" to climate change — from filling the skies with soot to block the sun, to cultivating oceans of seaweed to absorb the atmosphere's heat-trapping carbon dioxide.

Reality Check – Space Based Power
Submitted by hcm1955 on Thu, 10/18/2007 - 20:39.From http://newenergyandfuel.com/http:/newenergyandfuel/com/2007/10/17/reality-check-%E2%80%93-space-based-power/

Are you thinking that this post is a reality check on the viability of the space based power system? Nope. It’s a reality check of the stories in the press about what is in the report so you and I can learn something worthwhile.
The report is titled “Space-Based Solar Power As an Opportunity for Strategic Security” a commissioned report to the Director, National Security Space Office by the SBSP Study Group lead by Col. Coyote Smith (really).
There are two views coming into the study. The Department of Defense view is as a resource for military activities in the first instance and secondly as a strategic means to reduce tensions over energy supplies that put the US and its allies at risk. The other view is the public and private part of the investments and benefits from continuing to a likely construction of a facility. As the technologies change the report serves the most useful function to compare the probabilities now to the idea’s potential in the technology at the idea’s inception and then look down the road to see what technologies will need more research and development to establish a facility in the future. Things are very different now in the various technology fields to put a facility in orbit and get the power on line.
