This isn't the legendary atmospheric jellyfish. No, this is a concept sketch of the "Migrating Floating Gardens" by Rael San Fratello Architects. These photovoltaic flying gardens hover over cities and aggregate in areas in need of greening.

These sky-gardens are designed to occupy "non-Cartesian space" and would navigate using GPS and GIS sensors. According to the garden's designers, this flying greenspace wouldn't be limited to any one city:

The gardens would be suspended in the air from large remotely controlled dirigibles. Each inflatable craft would house thousands of smaller plants attached to long vines. A family of dirigibles would migrate within a city, moving towards areas where the heat island effect is greatest, and also migrate seasonally, traveling to southern cities during winter months and northern cities during summer months.

This is all well and good, but it's just a matter of time before a nefarious criminal mastermind hijacks these skypods, fills the planters with poison sumac and durians, and holds entire cities hostage with an itchy, stinky swarm.
