[math-fun] Commutapult: Catapulting Commuters
FYI -- I had a similar idea a number of years ago to provide "cheap" L.A./SF flights. Relatively long acceleration & deceleration ramps required to keep passengers alive. Some significant problems in recovering the energy involved to reuse in next flight. Also, even minor changes due to air pressure/temperature can affect where the vehicle lands, so some steering mechanism is required. http://www.commutapult.org/
Had me gurgling from start to finish. Another good reason to stay away from Seattle ... WFL On 8/9/10, Henry Baker <hbaker1@pipeline.com> wrote:

Aha! Combo satellite dish & pizza catcher: order the pizza & Netflix together... Considering the fact that several centuries of math & computers were funded by calculating shell trajectories, we ought to be able to put these calculations to more peaceful uses. In New York & especially Chicago, around the turn of the (20th) century there was a pretty decent system of pneumatic tube transmission. I don't know if they were able to develop a roll-up pizza to deliver this way. http://en.wikipedia.org/wiki/Pneumatic_tube Perhaps pizza delivery won't work this way, but the "Canwich" would be appropriate to deliver either via a gun trajectory or a pneumatic tube: http://markonefoods.com/index.html At 08:00 PM 8/9/2010, rcs@xmission.com wrote:

And then there's "Rocket Mail" -- one of my favorite forays of the postal service into (wildly impractical) technology: http://en.wikipedia.org/wiki/Rocket_mail On Tue, Aug 10, 2010 at 10:56 AM, Henry Baker <hbaker1@pipeline.com> wrote:
