Presented at the 2024 Klima Biennale Wien, Mid-air Collisions reflects on the interaction between the environment and the infrastructure of renewable energy sources. At Ivanpah, a concentrated solar power plant in California’s Mojave Desert, sunlight is reflected by more than 170,000 motorised mirrors, reaching temperatures of up to 1,000 degrees Fahrenheit—attracting insects and birds that perish in the intense heat. Kathrin Stumreich recorded observations of thermal activity and animal behaviour around the solar facility.
