Ivy Zeppilin

Hanging gardens... that hang WAY UP

After seeing the flying trees talk, I got to thinking... what if we planted ivy on zeppilins, and sent them up?

As the ivy grew, the zeppilin would get heavier, when it eventually sinks back to the surface, the ivy airship can be pruned & repotted, and then it can be sent back up. The costs will be prohibitive, and I don't see any pracitical reason for this, but oh well.

       Balloon gardens, croissant - but I don't think ivy would work. You need plants that are accustomed to getting moisture from the air.

       Bromalids? Sp. For flying trees look up. Look waaay up, and I'll call Rusty.   

       Ahh, Bach.   

       Oh, the biology!

       //don't see any pracitical reason for this// - that's why I like it - beautiful, fantastic, and without any tangable benefits - if only politicians, managers and accountants thought more like you Madai, the world would be a better place.

       And as we wind on down the road
The ivy taller than our soul.
There walks a Madai we all know
Who plants green vines that want to grow
It serves a purpose, though untold.
And if you listen very hard
The tune will come to you at last.
When all around the blimps are green
To be a sight and not be seen.

       And s/he's growing an ivy-rope ladder to heaven...   

       Sorry, I had to. I saw the idea title on the overview page and just thought, “wow, ivy zeppelin would be a terrible name for a band”. On the plus side though, I love the idea. These would look like huge airborne jellyfish roaming the land.

       Actually, I think of it more as the color of a saline breast implant that's been infested with bacteria. Either way, though, it's still pretty cool.

       I'm wondering what those flying trees had to say. Probably something like:   



       yeh, those trees. Always with stuff like that.
bungston, Jul 26 2004

       I notice no one has boned this yet. Even if you don't really get it, there's *nothing* negative here, so who could possibly object? Croissant, slightly straightened hanging in the air and covered in moss.   

       [luecke]- I wish one could bun anno's.

       + for you, and the annos in verse.
absterge, Jul 26 2004

       Okay kids, I like the way it's going, but it needs two more things.   

       1. What's a gas that's lighter than air that we can get the plant to make?   

       2. How can we get the plant to make it's own balloon?   

       because once we get those two problems solved....   

       It's an organism!!!!

       Oh... {{horribly embarassed}} just got back from "flying trees"...

       perhaps beans could be grown downwards, like tomatoes.

       //As the ivy grew, the zeppilin would get heavier, when it eventually sinks back to the surface, the ivy airship can be pruned & repotted, and then it can be sent back up.//   

       When it reaches the ground, it'll find a stable equilibrium. Some of the ivy will trail on the ground, with the weight of the airborne portion of the ivy exactly cancelling the lift from the zeppelin.   

       You can sometimes see the same effect with a helium balloon on the end of a length of string.   

       Trimming the ivy just above the point where it meets the ground will leave the zeppelin with just enough bouyancy to overcome the weight of the remaining ivy, and it'll drift slowly skywards again.   

       (Oh, and I'm sure there's a Hullaballoon tie-in here somewhere.)
