The CloudMaker is a personal device for weather modification. It consists of cloud-making gear sent up into the atmosphere in a weather-balloon payload. As it reaches specific altitudes it disperses Cloud Condensation Nuclei (CCN), heat and water vapor. Moisture in the air condenses into cloud droplets around the CCN, forming into small clouds. 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.
