Sorry to be the bearer of bad news, but you've got a long hurdle to overcome since the threshold is now 100k,  Subby.

A space elevator is a worthy goal and I agree more research dollars are needed. However, I'm unwilling to funnel the lion's share of limited NASA dollars into it just yet. I'd rather have research put into NEO detection and mitigation, which is woefully underfunded. Perhaps if you petitioned to increase NASA's budget as well, I would sign it. On second thought, I'll sign it on the off chance it will actually get somebody to look at NASA and respond.

Only 3 more needed.

We have the technology to do this now?

Are you sure about that, subs?

You do realize that building incredibly high structures to not fall in on itself is pretty damn insane, right?

You also realize that it would be 50 miles high, right?

And where the hell was I?

I signed it, Smitty. Not that I agree 100% with the proposal, but it's something we should be talking about. Most likely, it will have to be an international project.

BalugaJoe: Only 3 more needed.


Interesting, I just loaded it and it says 5 more needed.

Oh - look more closely. I think you (and I) were looking at the wrong field. Now I see there's only 5 signatures (and most of them are Farkers).

/glad they increased the number of signatures needed. Shiat was getting out of hand for a while.

Should I bring up the fact that the mobile phone in your pocket, the computer in your car, and the device you posted on are all by products of NASA technology? Or that NASA's return on investment is the greatest of all federal funding?

Is Subby a Luddite or just an asshead?

You're off by nearly 3 orders of magnitude.

Anyway, one thing I never hear discussed about a space elevator, is that it has to be on the equator, and EVERY orbit intersects the equator. How hard will it be to avoid ALL orbiting space debris for X many years?

A space elevator??

The technology isn't there. The last time I looked into it, carbon nanotubes were right on the threshold of being strong enough, with zero margin for safety or cargo and no way to make them long enough.  Orbital debris and high energy particles will erode it away fairly quickly and there is no way to launch it into orbit.  You would have to build it there.

Oh, and orbits are more a trajectory than a location.  Simply raising something 100 miles up doesn't put it into orbit, it has to be accelerated to orbital velocity, which means that the forces on the cable are perpendicular to the cable itself, so it would take a long time to raise something to orbital velocity without destroying the skyhook, about 5 days to GTO according to the Wikipedia article.  That would limit capacity.

5 days on the elevator? A new era of rock opera muzak awaits us.
 
2013-01-19 03:00:28 PM  
It wouldn't be 50 or 100 miles long. Don't forget that the terminus needs to stay above the same point on the globe: i.e. it needs to be in a geosynchronous orbit.
That means a length of 26,199 miles.
Five days in transit would imply an elevator speed of around 200mph (which isn't unreasonable).

I think private industry will beat them. NASA may help with some early heavy lifting, but combined with the recent interest in "capturing" asteroids, it could end up profitable. I signed it either way.

Yeah! We don't need Medicare or Social Security. We need a 26,000 mile metal pole that may or may not work! Because rockets are boring. Or something.

Isn't a sky hook completely different from a space elevator?

One is tethered to the ground and reaches out far enough into space where the tension created by its rotation helps overcome load bearing issues at the base, while the other is a free spinning structure that dips part of itself into the upper reaches of the atmosphere or depending on proposed style down to near the ground, slowing greatly as it travels through the atmosphere to collect a payload and carry it back up to space.

it's a design proposal that's been around for awhile.

Really not sure if our materials technology is up to the strain on the structure yet, but the research would be interesting.

Uh, it would be impossible with current technology and materials science, and financhial capabilities to do it. You'd be better off investing in SStO technology and aerospace aircraft technology.

visionary?

Well, I suppose you could call delusion "vision". That's just about what signing that petition amounts to. Unless you just want to send a message, then more power to you.

If it happens, it will happen when it happens. Want to make it happen? Get really really really rich or become the worlds greatest engineer.

I haven't been paying attention, the last few years I've been focused on subsea stuff

I think these petitions were put in place to give people the sense they are doing good when in fact they are only a feel good measure that will be ignored by those who matter. Sorry to burst the bubble. If someone was going to make a space elevator, NASA would probably be the last one to do it.

What if I don't want to save the human race? What if I only want to save part of it? What if I am a far greater visionary than you are Subby, and want to save only the gorgeous young females and myself? Do you have a petition for that? No, I didn't think so.

White House Petitions...the new Facebook. "Like mine or else I will be butthurt!"

Idiots.

Do we need cheaper ways to orbit? Sure.

A space elevator sounds like a spectacularly bad idea, though, since it's almost literally a Sword of Damocles hanging over the Earth.

We need to get to Mars or the Moon first and build prototypes there.
