It does sound amazing and economical, like almost too good to be true, but I very much hope it is true. What are the downsides? Is there a degradation problem or something similar? Other than the stoner connection in people's minds, what kind of resistance is there to this? Why isn't it widely known? |

It may be that most people dismiss supercapacitors based on the stats for legacy (pre-graphene/pre-hemp) supercapacitors: large but quick and long-lasting.
It may be that hemp is taxed at up to 90% because it's a controlled substance in the US (but not in Europe, Canada, or China; where we must import shelled hemp seeds from). A historical accident?
