Smokers, don't get too excited! Don't assume that smoking a cigarette near your computer will enhance its storage capacity.

South Korean researchers have managed to convert used cigarette butts into a material which can be used to store energy. The material performs much better than currently used material such as carbon, graphene and carbon nanotubes. The researchers presented their paper in IOP Publishing’s journal Nanotechnology.

Professor Jongheop Yi, co-author of the study, said: “Our study has shown that used-cigarette filters can be transformed into a high-performing carbon-based material using a simple one step process, which simultaneously offers a green solution to meeting the energy demands of society.”

That doesn’t mean more people can start smoking now. What it does mean that the technology can help tackle the approximately 5.6 trillion used-cigarettes, or 766,571 metric tons, which are deposited into the environment worldwide every year.
This ‘waste’ can now be used to create high-performing material for storage in electronics.

I hope tobacco companies won’t come up with advertisements like, “each cigarette increase 5 terabyte of storage’ ;-)
