For small payloads you could hang a gun or coilgun based system from an airship Gun based http://www.columbiad.ca/industrial/index.html Coil Gun Based: ...
For a propulsion system why not use an electrical power steam rocket? This would require a water feed, electrical lines to be build into the tether. But a...
I see announcements that the space elevator challenge will be held at NASA Ames on August 4th http://www.spaceref.com/news/viewpr.html?pid=18314, and that it...
I would just like to clarify that I was refering to an *additional* cable system, running down the side of the SE, for the express purpose of transporting...
Please forgive me if this has been discussed before, but from the thinking I've done recently the benefits of this idea seem decent. Maybe you can find the...
About the problem to send the energy to the elevator itself... why can't we fix the elevator on the cable and, instead, move the cable in a round trip? Like...
Hi, as a competitor in said competition, I can safely say that it is going to be held in October, in New Mexico. Among the many reasons for this choice was the...
... It hasn't yet been clearly established that people SHOULD be riding the SE. Cargo, yes, but people? If you're lucky, they'll only get mild radiation...
Yes I suppose I could have been a little more clear in what I was saying. Start with the full SE, all 30,000 miles of it or whatever the final numbers work out...
... That's a bit like the idea I had, except I had a whole chain of these loops going all the way to orbit, mechanically powered from the ground. see: ...
Hi, Tomorrow in Airdrie Public Library (near Glasgow, Scotland) at 1 pm I shall be giving a talk on Space Elevators that will, among other things, feature ...
... I'm not sure how the side entrances / exits would work. Suppose the platform is 350 km up the elevator. Some rough calculations show that it would have a ...
My immediate question is, how do you justify that really heavy 400- mile-long pulley cable? If we can get power beaming to work, which seems actually somewhat...
... Actually, that's not right- I started off with that, but I soon changed to a series of pulleys of fixed size hanging on a conventionally tapered cable. The...
... Because the cable is a one-off cost, but the power beaming costs are for every launch. ... Power beaming is highly inefficient, mechanical power is much...
... pulleys ... heavy ... smaller ... Okay, I'm a little confused. In your version, we have smaller pulleys but a whole lot more ribbon, both a traditional...
You're probably greatly overestimating the extra weight of the conveyor belts. Don't forget that they're only strong enough to carry payload, and made of CNT....
Hi Ed, The LEO Station is suspended from the Geo station above on the same kind of nanowires as the elevator uses in order to maintain its position regarding ...
... So you're going to have vehicles heading right toward the station at better than 7 kilometers per second, decellerating furiously (say 4 g for 3 minutes),...
I'm sorry to hear that Bob smashes his garage to smithereens every time he brings his car home. As far as both velocities and the mass of the LEO station are...
... No, we have a speed limit on our street and in our driveway that's considerably below the 15,600 mph your vehicle would be traveling. More to the point, if...
Of course it would be wise to start with a simple, cargo-only SE. The SE with platforms at LEO-altitude is something people can dream about for later...
... Well, yeah, it would. If the platform is no larger than the current ISS -- 440 tons, interior volume about that of a 747 -- it will require an SE that's...
I agree that cargo only is fine until the tech is proven and deemed safe. But the ultimate goal has to be to get people into space, without that, there is ...
... To be honest, the ULTIMATE goal -- as I see it -- is to get ME into space. Without that, there is really no point to building any of it. We all sorta feel...
Hi Guys, I've only just got that last lot of messages, unfortunately just as I have to dash off, but will read, digest and get back to you - probably Monday. ...
Here's a new justification for the SE: we wait until Wall Street gets the idea that maybe it should do something about global warming, and then propose an idea...
... Yes, either that, or the New York Stock Exchange will be underwater and we'll hand our sovereignty over to the UN Environment Programme, which will declare...
