    h=y0+y*t+0.5*g*t^2=0+0+0.5*10*(10/2)^2=125m
    E=m*g*h=m*1250
    Thus, you've got 1250 J for every kilo in the Bremen facility.

    Your 1125m shaft from the previous post requires almost ten times the energy.

    Or, they could just take every computer that is upgraded/rotated out of a federal government facility and set it aside for this job. No, those computers must be decommissioned to avoid paying their OS and office suit vendor for another copy that goes on the replacement machine.

    There is, but it involves a virus-infected DVD and higher authority will find out in the end. I recommend to just keep thinking about your bunkmate's picture of his sister.

    Many of Parkinson's articles were humorous and he strongly hinted that he had no actual numbers to back up his claims. It's a little surprising to see that the real world aligns with his claims http://dilbert.com/dyn/str_strip/000000000/00000000/0000000/000000/00000/5000/500/5652/5652.strip.print.gif

    You speak like a physicist, not an engineer. In theory, you are correct. In reality, how will you launch the material, such that it travels at exactly 0 degrees from vertical, at the required velocity? Solving for v in m*h*g=0.5*m*v^2 I get 150 m/s launch velocity. At perfect vertical. On a payload that contains a manufacturing process, probably including a molten metal. More than a kilometer below ground level.

    ...enhance old film footage from the spacee program up to the standards of HD... I just want to take a brief issue with the wording here. There is likely little "enhancement" done for this film to reach "HD standards." And the word "spacee" didn't set off any red lights?

    It doesn't matter. The Shuttle was designed to be reusable. In order to meet that definition, at least X% (I think it was 66% but I'm not sure) of the launch mass, minus fuel, must be reusable. Whether or not it is safe or efficient is not important. If it were, we'd be flying Apollo-type craft (like the Russians still do) for missions that do not need the huge cargo bay of the shuttle.

    Note: according to wikipedia, the SRBs make up 60% of the launch mass _with_ fuel. Anybody know what that figure is minus fuel?

    I think the engines are too expensive to ditch. That's why the shuttle carries the three MSE engines on it's tail the whole spaceflight and reentry, when they could have been ditched along with the ET. Their extra mass is a burden for every manuver (sp?) yet they've got to come home somehow.
