Hemp battery

[dieter]

Thanks for your contributions, Smoky.


Indeed Coal is electricly conductive, well we knrw that since thw carbon-zinc battery etc. However, conductivity is usually rather low, too low for a capacitor, no match or substitute for metals, but... here it comes... Nanotubes, and Graphene-similar structures are found in hemp, whoch explains the extraordinary strength of the hemp rope (America wouldn'd be discovered if it wasn't for columbus' hemp sails and ropes, btw., any other organic cloth will rott away in 2 weeks on sea)


So, yes, we can carbonize any plant material, but they are not all very good conductors, where the nanotube-like structure of hemp really tends to go towards room temperature superconductivity, just like real nanotubes, but much cheaper to manufacture.


Bill Murray-Smith os the kind of dube who mods his inkjet printer to print ultrathin layers of his selfmade graphene, just to make a kitchen-diy mega farad capacitor, a fteakin million Farad, at much higher voltages than todays supercaps... just smashing, as our britisch friends say.


He also tested Bamboo, which was not so effective, and seaweed, which was very good. You have to watch his stuff, esp. in this context.


Tinman also picked up Bills Graphene Cap methods and I would be surprised, if he isn't already testing hemp.


Speaking of which, you should be able to buy in the home improvement store, plumbers hemp, very cheap and already seperated from the useless parts.
The use it to tighten wazer pipes at thw screwed sections, hemp deposits chalk, which is then making it 100% watertight. The company Dupont has a teflon tape as a substitute, costy and cannot be used multiple times... they also tried to market their nylon patent by criminalizing any hemp fibre, well, that's an other story.


So, ok, hemp in carbonized in the hydrothermal carbonization process, at 180 to 200 deg celsius for 24h. Maybe possible in a stream pressure pot. Bill mentions to add a bit of acid to help the xarbonization, tho that must be washed out afterwards.


Then was mentioned they soaked the fibre in something, maybe sodium whatever thingy, do you know anything about that,Smokey?


I'm also interested in the inkjet printer mod, what would you use as the liquid substance in the ink? Glycerine, Water... anything else?


BTW. there is industrial hemp, especially cultivated to have low amount of psychoactive delta-9-THC, this is legal in any country, usually up to eg. 0.99% THC at max, tho a Farmer requires special permission to grow it. Anyhow, get plumbers hemp, hemp rope or hemp cord, it's precisely the fibre required.

BTW sorry about the typos.

Maybe cellulose?
Not sure, I know historically organic electronics have been
heavily chemically processed. Which to me seems to defeat
the purpose. I don't believe there is anything unique about
hemp, in particular, except that it is on the list of life forms
that produce these certain type of fibers.
The politics of hemp and its' medical cousin, are heavily
promoting this for their own goals.


It's a modest compromise, because they help expose the truth
about organic electronics.
Prepared spinach leaf proteins have magnetic properties
Hard fibers can be prepared with capacitive properties
Flax bast is electrically similar to hemp
Jute, Ramie, or any dicotyledon.

Organic Chemistry is a synonym for Carbon chemistry, where, unlike most other elements, carbon can build extremly complex molecules, even up to nanotubes. Therefor molecular properties of plants differ greatly. Besides hemp being the cure for cancer, I think there is indeed something special to it. Molecular structure is tubeoid, resulting in very special electrical features, although there are certainly more plants like that, eg. the hairs of certain palmtree stems, that are as tough as hemp. (cocos?)


That being said, only after carbonization any of these cap / battery features become available.


Furthermore, the right amount of grinding is required. You want it fine, but the nanotubes still intact.

This is correct, processing of the fibers must be adequate, without damaging the fiber structures.
Side dependent variables are present for each fiber type.
Microstructure does play an important role, and various fibers have different properties.
While hemp or flax might make great interfaces for i.e. Electrodes, connectors, plugs
Certain algae might be more suitable for its capacitance, or as a storage medium.
I think each type of fiber will play an important role in understanding our full potential.
