Could we make tennis rackets out of atmospheric CO2? Science says yes

By

You know the old saying: “When life gives you atmospheric CO2, capture it, turn it into carbon fiber, and build cool stuff with it.” No? That’s OK — I just made it up, but let the record show that if this does become an old saying, you heard it here first.

The fibers in this microscope image are made of carbon, produced via a new method that also removes carbon dioxide from the air.

Researchers at George Washington University have figured out a way to transform everyone’s favorite greenhouse gas into the super-strong and lightweight wonder material known as carbon fiber. As MIT Technology Review reports, carbon fiber (and especially carbon nanofiber) has become somewhat of a darling material among engineers, who are using it in all kinds of things: airplanes, cars, tennis rackets, wind turbines. Unfortunately, carbon fiber can be pretty expensive to make, which is why chemist Stuart Licht and his colleagues at GWU are actually killing two birds with one stone. Their technology both sucks CO2 out of the atmosphere and makes cheaper carbon fiber.

According to Technology Review, Licht and his team estimate that with their technology, the amount of atmospheric CO2 could return to pre-industrial levels within ten years — and that’s even if we don’t significantly slow our emissions in the interim. All they’d need is an area about 10 percent the size of the Sahara Desert in order to capture and convert enough CO2 — a process that involves dissolving the CO2 into molten carbonate.
