Although controlling the weather is a controversial topic, media artist, designer and animator Karolina Sobecka has created the Cloud Machine. This device for weather modification travels up into the atmosphere via weather balloon.
Once it reaches a specific altitude, it disperses Cloud Condensation Nuclei (CCN), heat, and water vapor. The moisture in the air condenses into cloud droplets around the CCN and creates small clouds.
Sobecka writes that this method is inspired by “a geo-engineering technique proposed to create brighter, more reflective clouds which shield earth from sun’s radiation, and thus partly counteract the climate change.”
