Scientists might have found a way to tackle climate change while looking for cheaper ways to make carbon nanofibres. Because they're expensive to make, carbon nanofibres aren't used much except in batteries and computers. Now a new way has been found to make them, by taking carbon dioxide from the air. This opens up the material for other uses such as car parts.
The new method can currently make 10 g of nanofibres an hour. Its inventors say that if it could be scaled up it might make a real difference to the amount of carbon in the atmosphere.
