3 or 4 mile long tube made of nylon other very light material leading to the balloon. Hot air from a source on the ground inflates the hot air balloon to hights not limited by the length of the feed tube which is in itself a lighter than air floating structure due to being filled with heated air.
This
has to be patentable, somebody would have done this if it had been thought of.
Alternately you could even put some measure of flammable gas in the heated feed tube to ignite when it gets the the balloon at the top to make up for cooling at those heights. Might even have little mini furnaces every few thousand feet or so that it burns just a bit of the enriched hot air/fuel mixture as it rises.
Sometimes it's fun to just be creative.

What the 6 story tall flailing man replacement would look like.

Helium replacement needs to be explored

Don’t know about the size. Probably keep it in my garage. |

Adding a jet exhaust to the bottom of the balloon to add some lifAksi making a scaled down version, maybe a few stories tall to compete with those car deal flailing men. Add some arms and a head too. Ten story flailing man. |

What advantage is there over a hot air balloon that carries its own heating apparatus? |
|
| |
//miles long// If it were thousands of miles long you could use it as a space elevator. |
|
| |
No, but there's usually some reason for generating any idea. ie it which be just for decorative/spectacle reasons if they were all brightly coloured tubes - like beanstalks...... |

This can stay up 24/7/365 to be used as a communication tower or observation post for instance without having to be taken down to be refuled. The fuel doesn't need to be compressed gas, could be something easy found in undeveloped countries, could even use wood. |

Or they could be decorative like beanstalks. You could put a thousand of these up for an art exhibit for instance. They'd sway in the wind like a field of wheat. Sometimes it's just fun to be creative. (link) |

But I gotta ask, how many millions of those 2 or 3 stories flailing men have been sold? Nobody's thought of just making versions of them that are 3 times as tall and just using hot air? They'd be shaped like this: (link) |

I find that really hard to believe. And the mile high temporary communications tower thing could really find utility in the real world. |
|
| |
How strong is the jet stream at that high altitude? |
|
| |
My idea also doesn't need expensive helium which would obviously not be applicable to things like 6 story talk flailing man displays. |
|
| |
Talking about various different proposed uses doesn't preclude previous suggestions. |
|
| |
And the HB is about interesting ideas. Just seeing how high you could make one of these things because it would be interesting is reason enough. |
|
| |
It’s daft enough for my approval. |

Thank you xen. Check's in the mail. |
