(...) Yep, but it came no where *near* orbital velocity - about a factor of 30 to low in energy. I agree, it's a nice mechanism to get away from the atmosphere problem, but so do balloons (for a far lower cost, actually). no offense to Space Ship (...) (18 years ago, 8-Feb-07, to lugnet.space)

These rocket sleds are a fun little build, and what a team. Beyond that, I'd like to thank you for almost single-handedly replenishing the oxygen tanks of .space. That you have brought such humour, classic style and quality photography with you is a (...) (18 years ago, 8-Feb-07, to lugnet.space, FTX)

(...) When I made the suggestion I was picturing a really long version of the 6394 Metro Park & Service Tower "elevator" mechanism. I guess it would work better to use technic racks with a worm gear driven elevator. That could even be motorized. My (...) (18 years ago, 8-Feb-07, to lugnet.space)

(...) On the other hand "Space Ship One" already surpassed NASA in efficiency with the use of a "carrier plane" to get a much higher start. Building a plane specifically designed for high altitude super sonic launching of "rocket ships" is one easy (...) (18 years ago, 7-Feb-07, to lugnet.space)

(...) I did some preliminary studies for building a space elevator. I think with some very significant selective compression of the diameter (and length) of the cable, the anchor station and the cable cars could be done. I was considering the LoM (...) (18 years ago, 7-Feb-07, to lugnet.space)

(...) The problem is rockets use reaction mass, and need to carry it along, so the rocket equation enters into everything you do. And honestly a rocket is not a very good way to use the energy: you have to launch at high speed (rocket equation (...) (18 years ago, 6-Feb-07, to lugnet.space)

(...) All right, all right... I just bought some gray wheels via BrickLink... Definitely interested to see how the real thing looks when they get here. Guess I'll have to make something else with 18 big blue wheels. ;o) Thanks all! -best, Wolf (18 years ago, 6-Feb-07, to lugnet.space)
