This “personal device for weather modification” can literally create clouds above your head.

The device deploys cloud condensation nuclei (the tiny particles that seed clouds), water vapor, and heat when it hovers at certain altitudes.

This should theoretically create small--but real--clouds.

It’s inspired by the idea in geoengineering of making brighter clouds that reflect more of the Sun’s rays to mitigate climate change.

China and India both use cloud seeding as part of their domestic policy. But whether it will work for climate change is still a guess.

DIY Geoengineering: A Machine To Create Clouds Above Your Head

If it’s ever just a little too sunny out, this "personal weather modification device" can add a little cloud cover to your day.

Are you a gloomy person? Artist Karolina Sobecka has created the perfect accessory for your feelings: the cloud machine, a “personal device for weather modification” that can literally create clouds above your head.

The machine, created for the Blowup: Speculative Realities event in the Netherlands, can purportedly spread cloud condensation nuclei (tiny particles that seed clouds), water vapor, and heat when it hovers at certain altitudes. This should theoretically create small--but real--clouds.

There is a larger purpose behind this. Sobecka writes on her website: "This method is inspired by a geoengineering technique proposed to create brighter, more reflective clouds which shield Earth from Sun’s radiation, and thus partly counteract the climate change."

Cloud seeding is one of the most common geoengineering practices. China famously seeded clouds during the 2008 Beijing Olympics in an attempt to prevent rain; in India, cloud-seeding has been used since the early 1980s as a remedy for droughts. Whether cloud seeding can--or should--mitigate climate change is still under debate. Sobecka’s project should help keep the conversation going.
