  1. Re:Why so tall? on Riding The Space Elevator · · Score: 1

    When you put something into GEO it will stay there. Right over the spot on the equator. There are perturbations over time, but it will stay in that orbit for quite a while. It's like the spokes in a bicycle wheel. The spokes from the hub all go straight out to the circumference. One of these spokes could be the space elevator.

  2. Finally, an idea I can sink my teeth into... on Riding The Space Elevator · · Score: 1

    This is great! A space elevator by the mid-21st century. Come on guys, do you really think that we can squeeze any more juice out of plain ol' rocket motors? It just isn't going to happen. And what about fusion or fission? A fusion motor would melt a hole on the launch pad and a fission motor would blast you with radioactive particles. The space elevator is the way to go. For just the price of electricity plus a small fee, you can go to GEO in a few hours. If you want a round trip ticket, then you just pay the square root of the one way. But fifty years? I think that is just a bit too close, more like 75 or a 100 years. When the Bay Bridge in San Fran was built, it was after nearly a century of ideas, politicing, false starts, and failures. At the moment, we are still in the conceptual stage. We have a pretty good idea about building it, but still have a lot of hurdles to overcome. A project this big will require some mega financing and a definite revenue stream. This idea won't take off just to serve tourists, there will have to be an industrial infrastructure in space that has goods to ship back to earth.

  3. Elevator Disasters on Riding The Space Elevator · · Score: 3

    Fortunately, when the cab is decending the cable, it doesn't need a heat shield because it is dropping at a controlled rate and not dropping out of the sky like the Space Shuttle. The Shuttle is accellerating as it falls so by the time it hits the outer atmosphere, it's going pretty fast and generating a lot of friction. As far as terrorist bombings, the whole cable, all 25,000 miles of it plus counter weight, wouldn't fall out of the sky. If the base anchor was bombed then it would just kinda hang there and drift around a little. But if it was bombed towards the middle, then half would rain down on the earth and the GEO station would just stay there.

  4. Broadcast transmissions? on Free Barcode Reader From Radio Shack · · Score: 1

    From the FAQ:

    Do I need :CRQ software installed on my computer for my :CueCat to work?

    Yes. The :CueCat device and :CRQ software work hand-in-hand. You must install the :CRQ software for your :CueCat device to work. :CRQ software reads Cues that are placed in any broadcast or other medium with audio. By having both a :CueCat device and the :CRQ software and connector cord installed, you can receive web pages both from print and broadcast. :CRQ software acts as a media manager that stores, sorts, filters, and presents all the Cues sent to your computer by broadcast and print Cues.

    What kind of technology is this? I don't recall hearing anything recently about embedding URL's in audio.
