"Bucky" Terrariums
Sudden idea occurred to me regarding the ongoing need to feed the worlds expanding population, while not depleting the natural world.
Geodesic Spheres (as designed by Buckminster Fuller) - at a certain size become naturally airborne (when in the sun) - due ot their lower internal air pressure (same way a hot air balloon rises).
Might such structures be used as giant Terrariums? In them plants growing Hydroponically (or in some similar method) while the sphere floats above land (or sea).
Doing this would mean no land would be required - so a city (say) might be able to literally feed itself if it chose to invest in such things?*
Now there's a thought.
Interesting to me - anyway (a bit of blue sky thinking - excuse sort of pun - to others maybe)?
* For instance by paying for one to be built - and locating it over an ocean.

Speaks for itself really. A place where I put some ideas.
