Used-cigarette butts offer energy storage solution.. Smokem if you gotem !

I found this and figured those who were interested in a thread about cigarette butts polluting just about everything might enjoy the idea there is a solution to the problem. The butts can be transformed into a carbon-based material using a simple, one-step burning technique called pyrolysis.. Maybe one day smokers can sell their butts by the pound ? hahaha that gives a mental picture no ?

A group of scientists from South Korea have converted used-cigarette butts into a high-performing material that could be integrated into computers, handheld devices, electrical vehicles and wind turbines to store energy.
Presenting their findings today, 5 August 2014, in the journal Nanotechnology, the researchers have demonstrated the material's superior performance compared to commercially available carbon, graphene and carbon nanotubes.

It is hoped the material can be used to coat the electrodes of supercapacitors—electrochemical components that can store extremely large amounts of electrical energy—whilst also offering a solution to the growing environmental problem caused by used-cigarette filters.

Maybe those who smoke can just smell their computers or handheld devices once this method goes full bore... Next thing you know there will be signs saying, "No smelling hand held devices on the premises"! OK a little out there for no doubt the burning process takes care of that.

Interesting .. good to see thryre finding a use for them .. wonder what they pay for used ones ?
