Industrial hemp, the non-psychoactive cousin of marijuana, can play a role in manufacturing super-powerful supercapacitors for energy storage at a cost that’s far cheaper than graphene, researchers report. The hemp-based technology took center stage Tuesday at the American Chemical Society’s national meeting in San Francisco. A team led by David Mitlin, an engineering professor at Clarkson University, heated up hemp fibers to create carbon nanosheets that can be used as electrodes for supercapacitors. Compared with graphene, the hemp-derived carbon is “a little bit better, but it’s 1,000 times cheaper,” Mitlin told NBC News.

Isn't graphene still pretty far from its final (asymptotic) economies of scale price?
You can do anything you want with laws except make Americans obey them. | What I want to do is to look up S. . . . I call him the Schadenfreudean Man.

Most graphene stuff is done on silicon to provide a support layer. Very expensive. I'm assuming that the fiber nature of hemp provides the support for processing and what ever is left over after pyrolysis also provides support.Betruger wrote:Isn't graphene still pretty far from its final (asymptotic) economies of scale price?
The place I first saw this (you can guess the type) was funny. They called it a battery.
