@jgmac1106 ↩️ Space needles, solar, precious metals that make the world turn Long term I think equatorial Africa will be a major connection to economies and off-world resources and industries (twitter.com/_/status/1584526679979925504)

@seeitfromspace ↩️ Space needles? (twitter.com/_/status/1584538918376341504)

@jgmac1106 ↩️ We have started experimenting with spin launching into space. https://bit.ly/3guoa6B Humans are squishy though.... Economically space elevators might be the most economical way to lift meat into space (twitter.com/_/status/1584557265268400128)
#
@Fundmasstransit ↩️ A few of us used to mess with something like this in KSP, mine operated in orbit to get the extra kick from orbital velocity https://youtu.be/vS74SsBd3eQ (twitter.com/_/status/1584558973704843264)

@DaveUthoff ↩️ The problem is the highest velocity is in the thickest atmosphere. Never could be used for a person due to rotational g forces. I'd think a rail gun might be better. (twitter.com/_/status/1584565276195987456)
#
@DaveUthoff ↩️ Trebuchet revisted. There is no free lunch with energy requirements. (twitter.com/_/status/1584564559431364608)
#
@DaveUthoff ↩️ 10000 gs (twitter.com/_/status/1584566588132364288)
#
@Fundmasstransit ↩️ Just a mild 200gs, LOL (twitter.com/_/status/1584566167863115776)
#
@Fundmasstransit ↩️ You got that right. Damn thing looked like a drunkard's sad attempt at solar sail. Couldn't/wouldn't launch, had to place everything in orbit and assemble there (twitter.com/_/status/1584565709190795264)
#
@DaveUthoff ↩️ Inefficient. Like I say....highest velocity at highest resistance (twitter.com/_/status/1584567653837942786)
#
@jgmac1106 ↩️ That is why this this last few launches are so exciting. They are sending high end components facing these kinds of G's. #ScienceIsAwesome (twitter.com/_/status/1584566654025060359)
#
@Fundmasstransit ↩️ That feeling when your skull crushes your spine but is also the size of a softball (twitter.com/_/status/1584566643815915520)

@Fundmasstransit ↩️ Trebuchet memes has entered the chat (twitter.com/_/status/1584573923928133633)
#
@jgmac1106 ↩️ Fuel is heavy (twitter.com/_/status/1584574344100978695)
#
@DaveUthoff ↩️ True....but the ideal velocity profile is to reach terminal V (17500 mph for true orbit) at the end rather than beginning. (twitter.com/_/status/1584575625385299968)
#
@seeitfromspace ↩️ I've seen this. But, where are the needles? (twitter.com/_/status/1584576966468202499)
#
@seeitfromspace ↩️ So, you just use a phrase like 'Space Needles' without backing it up? (twitter.com/_/status/1584578319688683525)
#
@jgmac1106 ↩️ Edwards, B. C. (2000). Design and deployment of a space elevator. Acta Astronautica, 47(10), 735-744. https://bit.ly/3zaG30U and https://bit.ly/3DmjqIj (twitter.com/_/status/1584580454673485825)
#
@jgmac1106 ↩️ Or you are missing conversation where we were talking about visionof Africs. See note of telecoms that do good. We were already talking science fiction (twitter.com/_/status/1584579738168950785)

#
@seeitfromspace ↩️ So, instead of saying 'space elevator', you say 'space needle'? (twitter.com/_/status/1584583780949692417)
#
@jgmac1106 ↩️ Depends on which science fiction author you are reading. Needle and Elevator used interchangeably (twitter.com/_/status/1584585663185158156)
