A little about me...











Hello, I'm Dag. I started VideoSift back in February of 2006. Since then it's grown into a wonderful place, built together, by many talented people.

It is nice when you full screen your second monitor while you are working or whatnot, do your thing on one monitor but the second have this fire full screen. Really nice to be honest.

No secret rule required. Having a beer is good enough by me.

Ha - no, not inappropriate at all. There's a secret rule that any Sifter who comes to a meet up gets their banishment revoked. I think.

Heya Dag

Hope you don't mind a banned user infiltrating your sift-up. I'm a nice guy, and would be fun to have a beer with you (and whoever the secret person is flying in...Lucky?)

If you think it's inappropriate, I'm fine with that.

I just saw the slingatron as you posted it a while back (the video you posted was private, but the link worked). While an interesting idea, they did seem to ignore a few things, most importantly the value of air resistance at sea level (or near it).
The issue is this...normal space vehicles travel at slow (relative) speeds when in the lower atmosphere, this limits drag and friction caused by air resistance. When spacecraft re-enter the atmosphere they must do so carefully, at specific angles and speeds, in order to avoid too much friction or they'll burn up (no matter what you make them of) or bounce off. When they are at high speeds, it is in extremely low air pressure, and vice versa.
This slingatron plan puts the craft at maximum speed in maximum air pressure. That's going to cause massive shock loads on the craft from turbulence, and also major friction and heat. I get the feeling those are insurmountable issues that ruin this plan.
A better plan I've heard of is basically a giant electro magnetic rail gun (cyclotron or straight linear accelerator) that is sealed and vacuumed as close as possible to 'empty'. If such a device could have it's exit point high enough (say, out the top of Mt Everest) it MIGHT avoid most of those pitfalls, along with the massive G load caused by spiral track acceleration (coupled in some slingatron drawings to an even higher G load 'launch ramp' at track end).
Just a thought for a tech minded 'buddy'. Enjoy.

It's really good to see old-fashioned mechanical engineering applied to a hard problem. I'm backing this project - and if you're interested in making access to space cheap, you should too.

Though don't expect to be riding one of these - 10K gravities ... might be a little uncomfortable. (splat)
