Hemp Fibers Make Better Supercapacitors Than Graphene

Posted by samzenpus on from the burning-up-and-down dept.

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.

    This will give new meaning to the term 'magic smoke'.

    Have you ever made hemp fiber supercapacitors...on weed?

    Dang it folks, I left the farm to be an electrical engineer and it keeps following me! I ran away from the farm for a reason, and bailing twine was wrapped all around it.

    Now we are going to be making capacitors from bailing twine? NOOOOOO!! I won't do this again!

    I have to retire before they start sending me out to pickup packages of dried grass and haul them to the barn again.

    Well, every technology has bugs and birthing pains. Keep working at it, and perhaps you can graduate to a better class of hemp, Mr. Mitlin.

      Side note, hops are also related to pot

      As are pine trees, sharks, monkeys and potatoes. But not humans, we were made by a wizard separately.
