California Startup Creates Dairy-free Butter

California-based Savor has created butter made from air instead of milk. The startup, which is backed by Bill Gates, has been working on creating dairy-free ice cream, cheese, and milk. Instead of using dairy, Savor uses chains of carbon dioxide, hydrogen, and oxygen instead. Reducing dairy use could help with the environmental impact humans have on the planet. However, Savor CEO Kathleen Alexander predicts the “air butter” won’t be on shelves until at least 2025. (The Guardian)
