https://time.com/collection/best-inventions-2020/For centuries, vodka has been made by fermenting grains like corn and wheat, a process that naturally results in carbon emissions. The Brooklyn-based startup Air Co. thinks it’s found a better way, distilling the spirit from nothing more than water and carbon dioxide, in a process that transforms the CO² into ethyl alcohol. Not only does
Air Vodka (starting at $65 for 750 ml) do the trick in a Moscow mule, but it’s also carbon negative: for every bottle that’s produced, the company’s NASA-award-winning technology removes about a pound of carbon dioxide from the atmosphere.

“Clean” rooms, in which air remains contained in a closed system for filtering rather than mixing with the rest of the facility, are in high demand at hospitals. Enter the
OptiClean ($2,000–$4,000), a mobile air purifier built by Carrier that has two air-scrubbing functions. It can turn any room into a so-called negative air-pressure space to prevent potentially contaminated air from flowing out, pushing it instead through a high-efficiency HEPA filter before releasing it back into the room. Or, it can simply filter out pathogens from a room. So far, the company has 15,000 orders for the units from hospitals as well as schools, universities, offices and other buildings looking to provide safe indoor environments.
Creating the tons of steel and concrete we use to build our world requires a massive amount of heat—and most of it comes from burning dirty fossil fuels.
HelioHeat cleans up that process by using the power of the sun. Here’s how it works: A field of 100,000 motorized, computer-controlled mirrors concentrates sunlight in the direction of a 40-m-tall tower, “like a giant magnifying glass,” says Heliogen founder Bill Gross. There, a hot spot gets up to 2,000°F, where the heat can be harnessed to melt steel or make cement or electricity. Future iterations of the tech, says Gross, could use the sunlight to create hydrogen to power zero-emission automobiles.
