Researchers at Air Co. in New York City are brewing up carbon-negative vodka "out of thin air" using only water, renewable energy, and atmospheric carbon dioxide.

The entrepreneurs use a small, solar energy-powered machine to pull CO2 from the air so the gas can be split into carbon and oxygen. Once the separated molecules are mixed with water over a metal-based catalyst, they reform to make pure ethanol.

> The process uses the same principles as photosynthesis in plants, but does so more efficiently. Following conversion, we distill the 10% ethanol to 96.5% in a custom-built, 18-plate vodka still followed by additional proprietary, trade-secret processes to purify and dilute the ethanol to a 40% alcohol-by-volume vodka. ~ Electrochemist and Air Co. co-founder Stafford Sheehan told [Popular Mechanics](https://www.popularmechanics.com/science/environment/a29715699/carbon-negative-vodka-air-co/)

While brewing up a typical bottle of vodka might produce about 13 pounds of greenhouse gas emissions, Air Co. vodka actually captures one pound of CO2 for every bottle produced, which is the equivalent daily carbon intake of about 8 trees.

Additionally, the alcohol is more pure than typical vodkas because it doesn’t require distillation to remove all the impurities from grains, yeast, or fermentation processes.
