I found this article quite interesting, it seems to me this process can be easily changed (pullling the catalytic surface back at a continuous rate) to allow...
RE: Closer! The method could be used to mass produce carbon nanotubes within five years, and for practical applications within ten years, said Hata. ... I...
I agree on your skepticism about goevernment funded *space* projects. They tend to cost a lot of money, run for many years, and have small supporting...
I think there is a keen competition on getting good CNT yarn going, as it would have a variety of uses, from bullet-proof vests to fishing line and marine...
... It is somewhat relevant because in both cases you are going to be comparing with the depth of the gravity well you are in (also energy over mass). It gives...
... I seem to remember that the current generated was enough to damage the line. (Likely there was more than one such experiment.) -- Anton Sherwood,...
Hi All, New member here. Oddly enough, I just thought I'd mention, I'm writing a story* about people experimenting in using a space elevator as a power source....
Hi Scott, ... Is this a space elevator that is attached to the Earth? If so, what is keeping it standing? Or is it a compressive structure? ... This is a...
Hi Blaise, ... In the story, this is really just an experimental proof of concept. A nanotube tower 300KM tall. The idea is to explore what sort of forces a...
G'day space cadets, There's a question of what data was obtained during the NASA tether experiment, regarding energy levels produced. Not to flog a dead horse...
FYI I read that a company developed a shuttle capable to deliver to orbit at the worldwide lowest costs. It could be the right choice in order to put in orbit...
It sounds like it is at the very early design stages for now, and they haven't had any news since April 2001. I'm not getting my hopes too high for now. And I...
I have just checked out the news at www.alphaspacepower.com They have updated their news and seems they are going to assemble their reusable launch vehicles...
Try their career link, it doesn't work. One would think if an organization was about ready to assemble a vehicle that they would be ramping up with techs,...
I read their acknowledgments and it seems they did a huge work and that they got government endorsements for that. It doesn't seem they are a couple of guys...
I wonder if the Alpha Group they refer to is the Russian Alfa Group? But, I did not see any mention of Alpha Space & Power on their web page. I agree that it...
They just answered to the email I sent them yesterday. They told me that they don't put any picture or information in order not to reveal the details of their...
Here is news article discussing shuttle repair kits: http://www.usatoday.com/tech/science/space/2004-12-06-shuttle-repair- kits_x.htm. This brings to mind the...
I believe any US company that builds something that can be launched or operate in space will require a license from the FAA AST office, even if this something...
On the other hand using He-3 from the lunar surface might be the better option. I believe a Lunar SE could be build sooner than an earth SE. See links Lunar SE...
Quick overview of state of the art in modeling nanotech. Some of the issues are: - Limited funding from the commercial sector. - Availability of large...
In my opinion, overstating the case is almost as dangerous as understating it. You come off as an extremist if you do so, and people can more readily dismiss...
Are there any cost estimates/studies out there of what it would take to launch raw materials using CHEMICAL LAUNCH VEHICLES versus SPACE ELEVATORS (+Build...
Abraham Nice reasoning. Here on the island of Maui, wind makes sense, but the method of figuring the costs makes no sense, as the environmental impact of a ...
All, For the near term I like the Biodiesel option, because it will not introduce additional carbon into the biosphere. To produce Biodiesel requires some type...
