I’m not sure of the physics/energy balance of this, but the visuals are certainly imaginative.

“This month, the Mongolian capital of Ulan Bator will begin conducting an ambitious “geoengineering trial” that will see the formation of an urban glacier that will cool the city throughout the summer months. As the Guardian reports, the scientists behind the 1 billion tugrik ($700,000) project believe that the glacier will emit enough cool air to be pumped throughout the city in the summer, while also supplying valuable water resources for drinking and irrigation as the ice gradually melts in the hot temperatures.”
