Hemp Fibers Make Better Supercapacitors Than Graphene
biodata (1981610) writes "BBC News is reporting findings published in the journal ACS Nano by Dr David Mitlin from Clarkson University. Dr. Mitlin's team took waste hemp stems and recycled the material into supercapacitors with performance as good, or better, than those built from graphene, at a fraction of the raw materials cost. "We're making graphene-like materials for a thousandth of the price - and we're doing it with waste. The hemp we use is perfectly legal to grow. It has no THC in it at all - so there's no overlap with any recreational activities," Mitlin says.
The pro pot crowd often makes reference to George Washington and other founders raising hemp. The hemp they raised for rope and fabric wasn't any good for getting high either. I suppose if you smoked a huge drum of it you might get a mild buzz but no reasonable amount of exposure would give you a buzz. Tobacco is actually worse in that regard. Picking tobacco leaves can put enough nicotine in your system to make you quite ill and that is without lighting it up.
