Maintaining a constant altitude, and thus preventing the balloon bursting, would be very cool.
AFAIK, that should be pretty easy. Just add ballast. Remember those helium-filled toy balloons that you can fly up and down with fans? They work because at the current altitude, the ballast approximately counterbalances the amount of lift that the balloon provides.
The amount of lift caused by lighter-than-air balloons is proportional to what's around it. Unweighted (and assuming a theoretical zero-mass balloon, zero-mass helium, and a spherical horse), it would rise until the point where the density of the air outside is equal to the density of the gas inside. Weighted, it rises up until the force applied by that density difference over its surface area becomes equal to the mass of the balloon and whatever is hanging under it.
Thus, the only reason the balloons burst is that they don't weigh enough to stop rising at a lower altitude. If they did, they'd just stay there at that altitude until the helium leaks out.
Alternatively, you can use a material that does not stretch as much. One of the reasons that balloons continue to rise beyond a certain point is that they expand at high altitude, thus lowering the density inside. If you limit the stretch, you limit the degree to which they can expand, making the density inside balance the density outside much sooner. Thus, they stop rising sooner (and they also don't explode because they don't ever get that thin).
Either way, there's just one problem: if they don't burst, they could potentially drift for thousands of miles over the course of several days (or even weeks) before they came down, and they could come down anywhere, at any time, into the engine of any passing aircraft, which is probably not what you want, hence the reason this is not typically done.

Nope, wouldn't work.
Buoyancy in air is caused by a slight difference in the total momentum from collisions with air molecules below and above the object. The air above has a slightly lower pressure, which means the (lots of) tiny molecules slam into the balloon slightly less frequently (density) and/or with slightly less speed (temperature) than those below. This difference matches the weight of a similar volume of air, which is logical in a stable atmosphere. That's why objects lighter than air go up.
As soon as the balloon starts moving up, though, the equation changes very quickly. The speed vector of the balloon will increase the relative speed of the molecules above, and decrease the relative speed of those below. This will reduce and eliminate the buoyancy effect rather quickly, resulting in a stable speed after a few seconds. So this is not just a matter of making a better balloon, streamlining it, reducing friction, etcetera. Sure, friction doesn't help, but the real problem is much more fundamental. The very reason why the balloon is being pushed up in the first place, disappears as soon as the balloon reaches a speed that is still very, very slow.

At least this group is smart enough to not claim that they reached space.

Of course not, but the Toronto Star certainly has trouble understanding the difference between "very high" and "space". Two front-page news stories on this in one day - a bit silly all things considered.

So, there's this guy on his first solo parachute jump. When the plane reaches the drop zone, he jumps. When he reaches the proper altitude, he pulls the main ripcord.

Nothing.

After a few seconds, he remembers his training and pulls the cord on the emergency chute. Still nothing. Now he's starting to panic.

Looking at the ground rapidly approaching, he notices a figure rapidly ascending towards him. "Odd", he things to himself. Nevertheless, when this other guy comes withing earshot, he yells over, "Hey buddy! Do you know how to work a parachute?"

"No! Do you know how to light a Coleman stove?"

Every time something remotely cool is posted (like a pair of kids doing a cool science experiment just because they feel like it) along some the jackasses to piss on it or pick pedantic holes in the wording of the article or try to gain karma points by way of some sad attempt at humour.

Why not launch a rocket from the baloon by fervus · 2012-01-25 23:52 · Score: 3, Interesting

My calculations might be wrong here, but I've always wondered... If a high-school can launch a helium balloon to a height of 24km, and also launch a homemade rocket that can rise as hight as 30km, couldn't some high-school class launch a rocket from the top point of a helium balloon to reach geosynchronous orbit? Wouldn't that be a feat more worthy of commenting? What would be the problems with such a lauch?

Re:Why not launch a rocket from the baloon by MachineShedFred · 2012-01-26 00:43 · Score: 1

Well, for one thing, orbit isn't about altitude. It's about matching horizontal velocity to the perpendicular force of gravity, so that by the time gravity would put you into the ground, the ground isn't there any more. Altitude helps, because gravity has a lot more work to do at that distance.
Technically you could orbit at 50,000 feet of altitude if we didn't have an atmosphere and you had sufficient horizontal velocity.

Since I am sick of seeing this post, I am going to start unilaterally modding down Overly Critical Guy and bonch (the two people your GreatBunzinni is complaining about), wheras without this constantly spammed post I would have ignored both. I encourage others to do the same. Note, if GreatBunzinni spams his comment over and over, I will mod him down too.

I don't care if the accusations are true or false, it isn't the point. The point is, your constant bitching and moaning about the situation has caused enough ire that I will now directly attack the person you are trying to protect. (and if the AC that constantly spams this happens to be either of the above two posters, so much the better)

Here is how slashdot works, in case you were not aware: People who post a lot will eventually attract a stalker that mods them down at every turn. Your recourse is that if they are modding you unfairly, they will get metamodded down, and eventually no longer get mod points. So if you are going to post, post insightful stuff.

tl;dr: keep your flamewars AC where they are easily ignored (such as this post is). If you log in and post offtopic shit, either you or your friends WILL get modded down.

So what, and without Skynet..I mean Google...where would we be? Wallowing in an internet designed by Microsoft? I love Google, they deliver money to me while I sit back and twiddle with my website every now and again. So what if they looked the other way while prescription drug dealers used their ad system, crappy?, yes, evil?, no. I really don't care for the government regulating the sale of drugs anyway. So the whole thing being illegal is kind of moot in my book. Other than that, they have done nothing wrong, and if they have, the good they do far outweighs any negative behavior. It is a company full of a lot of people. Granted, they aren't perfect like you, but Google is putting pressure on governments and established wealthy strongholds just by their very existence. That is good thing for the progress of the entire world, something technology is good for and something which many other tech companies fail at because they are too busy learning how to fit into the political landscape.

In the Canadian media, gosh! this is all terribly new. Meh. I've been to /. too many times. Is it the 50th time this has been done in the last 2 years? 50? Am I wrong, 50? Even the designs are copied. At least they are learning from others, although they didn't have telemetry tracking that lots of others did. IMHO, real innovation would be launching the balloon to 50,000 or 80,000 feet, and when it bursts, 3 parachutes pop out, each slowing descent, but also pulling away from the (still recording) rocket, that launches ...at 50,000 or 80,000 feet, and goes up another 100,000 feet (likely more). Rocket relays pictures to (now descending) platform, that relays back to the ground. Both have controllable parachutes that lock them to a point on the ground (via GPS), so that they attempt to land within a few meters of the launch pad, within a day or two. *That* would be good.
