Look Kinda Scary I would need the bar
I'm sure it would be a fantastic experience, but gliding down to earth from 100K feet with a parachute I would need a lot of strong liquid courage.
US space flight outfit World View has successfully test flown a 1/10 scale model of its balloon-lofted passenger podule, and reckons it'll be ready to welcome paying customers aboard the full-fat version in 2017. The gondola hit 30,624 metres (100,475ft) before detaching from the mighty helium-filled orb, after which it …
"gliding down to earth from 100K feet with a parachute I would need a lot of strong liquid courage."
As the space equivalent zone extends upwards from around 60,000 feet (i.e. bugger all atmosphere in terms of slowing down with a parachute or stopping your precious bodily fluids from boiling), I think 'gliding' is an ever so slightly optimistic marketing term for the first 40,000 feet of descent.
'Freefalling' would be a kind way of putting it, others may prefer 'plummeting', 'plunging' or 'hurtling' as a more accurate description.
Either way, those consuming a lot of strong liquid courage to cope with the sensation might find that most of said liquid has somehow found its way into their pants.

I'm guessing more of it will end up on the outside of the passengers' clothes, along with other assorted stomach contents.
I'll just add this to the list of Things I Never Want to Do.
(Mind, I have no beef with those who are inclined to ride a balloon up and fall/glide back down. Just don't see the appeal myself.)
From the headline photo, it looks like you're going to be swinging around too much to drink anything. Probably a good job too, as anything aimed at the lavvy is likely to end up all over the floor and walls. I assume that the interior can just be hosed down after each flight.
wait, what? You just need simple fusion of hydrogen to get helium. You need Supernovas to get above iron.
Still, I'm not sure how "simple" fusion is. We can do it in the labs, it's just not giving us more energy that we put in, but if the point is to produce helium, not energy it might work. Again, I don't know how convenient this is, but it is done already in the labs.
"To be fair, this might encourage a little more research into making Helium out of Hydrogen, of which we _do_ have plenty."
Fleischmann & Pons, is that you??
Seriously - if you don't count the H-bomb our current fusion abilities are pretty pathetic which is why the fusion reactor is 10 years away and always will be. To make a useful amount of helium via fusion is way beyond our current capabilities.
Yep, I'm glad this company has perfected the Helium generator. No more worries about running out of Helium needed for our medical equipment or for welding critical structures. They can just whip up another batch of fresh, pure, sweet-smelling Helium and send another podule full of yuppie, adventure-seeking rich people to the upper atmosphere. That's a fucking great idea. Good work, guys, one of you should win a Nobel prize.
Running out of helium? Not really. No need for fusion here at home, the hard work's already been done long ago and far away. Helium is generated naturally by alpha decay all the time.
"Most terrestrial helium present today is created by the natural radioactive decay of heavy radioactive elements (thorium and uranium, although there are other examples), as the alpha particles emitted by such decays consist of helium-4 nuclei. This radiogenic helium is trapped with natural gas in concentrations up to 7% by volume, from which it is extracted commercially by a low-temperature separation process called fractional distillation."

Yes, hydrogen would be much better, and gives slightly better lift too - which will be worth a lot at the extremes of achievable altitude.
Funny how hydrogen is *Bad* in balloons (because "Zeppelin") but *good* in cars (because "Green").
(although hydrogen is actually used by the competition balloon folks)

It would certainly make you more mindful of the 'no smoking' rules
"
Why? People smoke in a car despite being closer to a more dangerous* highly inflammable substance than the people in the gondola will be.
*More dangerous because if it leaks it forms a puddle with associated bubble of explosive gas that stays around, while leaking hydrogen will usually dissipate within seconds.
Except Hydrogen in cars is VERY not green.
Maybe I should rephrase that. Green by greenie nazi definition maybe but in actual scientific and practical engineering fact another high fossil fuel consuming disaster until we get enough nuclear leccy to cover peak load and need something to use it for at other times.
Even then there are very good reasons NOT to use it for motor fuel.
So you can get up to 30000m with little or no vibration, this could mean cheaper launches of sensitive equipment as you don't have to protect it as much.
By the way can't you recover a lot of the helium by sucking it back into tanks in the pod prier to disengaging the balloon.

Apparently the additional weight of the compressor, storage tanks, and power supply makes this infeasible, according to some discussions of LTA flight I've seen.
I was curious about that myself ;)
I'm sorry, despite the company's name and FAA stipulation, IMHO that's not space. I would be happier with their system if they weren't letting a large amount of helium go bye-bye. And I don't see any reference to a method for managing the balloon after separation - will it just float around for a while, acting as a hazard to aviation? (Perhaps it has a 'dump valve' and a radar reflector, which would be better than nothing.) For the cost of another two hundred kilos the system could decompress mist of the helium and open its own parachute, ride down with the capsule, or (coolest but most difficult) zip open a couple of seams in the balloon to become its own parachute.
I can't see the issue with using hydrogen. If it goes pop before launch, you are happily inside a spacecraft sitting on the ground. Once you have launched, where is the ignition source? And if it does go pop at altitude the flame goes up, you go down, and then you deploy your chutes. And no worry about static at landing, because you aren't bringing the hydrogen back.
Twice the loft:- so smaller balloon, bigger payload or higher altitude.
A reusable dirigible could lift and drop gondolas every few hours simply by pumping gas into and out of a lift bladder.
The gondolas themselves could be given an aerodynamic shape. A lifting body which would slowly spiral to ground over a period of an hour or two.
