- Re: Re: Space, the final frontier
-
- I'm not interested, especially, in impugning the technical integrity or
- honesty of those working in the aerospace industry, I know that there are
- many honest, dedicated, and competent people working there. I just want them
- to defend their views. If they have genuine objections based on physical or
- technical grounds that demonstrate convincingly that large scale fixed launch
- systems such as the rail gun or laser propulsion systems can't be done, or
- that given such systems, that we can't put the kind of infrastructure into
- space required to industrialize it, or that given that infrastructure, we
- can't use it effectively to gather energy and other resources... if this isn't
- worth doing, I'd like to know it. Perhaps technical objections can be
- answered, possibly by people working in these or related areas.
-
- What I'm saying it... they said this can't be done. I want explanations as
- to WHY. (if those personally offended by this want to read this as an
- invitation to come out and fight... that's OK as well.)
-
- Amd as for Steve regarding launch vehicles and frictional heat... there's
- a big difference between a few minutes of heating via rail gun and hours of
- continuous heating at supersonic velocities. Low cost ablative coatings,
- vapor phase cooling and other methods can be used. As for limiting freight
- to 10 gravities, why? While I wouldn't care to ship the computer in front of
- me this way as an intact box and have any faith that it would boot up due
- to nasty things which would happen to the connectors (card, possibly even
- SIMM, worst case, DIPs in sockets) I wouldn't in the least bit concerned
- about shipping the computer in knocked down form... the box taken apart,
- the boards wrapped in bubblewrap and secured to a rigid surface...
- I see no reason not to ship electronics broken down and properly packed
- at 25 Gs. Or not to ship CNC tools, lab equipment, fab equipment...
- or the other equipment needed to build space factories and habitats.
- (note: the rail gun needed for a 25 gravity launch is MUCH smaller than
- Steve's 400 miles. And quite a bit cheaper.)
- Blessings...
