Possible Graphene Alternative Made From Hemp Waste
MTorrice writes "A low-cost chemical process can turn hemp fiber into carbon nanomaterials. Researchers used the materials to make devices called supercapacitors that provide quick bursts of electrical energy. Supercapacitors made with the hemp nanosheets put out more power than commercial devices can."
According to one of the authors, "Hemp bast is a nanocomposite made up of layers of lignin, hemicellulose, and crystalline cellulose ... If you process it the right way, it separates into nanosheets similar to graphene." Perhaps the process could be applied to related plants (hops?) too.
My ashtray is full of carbon nanomaterials stemming from hemp products.
Am I rich now?
They're the same species, so yeah, probably close enough.
They did in fact create a system that puts out more instantaneous energy per unit weight, but that is not the improvement that super capacitors need. They have improved gravimetric power density. The two measures that need improvement to make super capacitors more useful are gravimetric energy density (how much energy can it store in a given weight), and volumetric energy density. How much energy can it store in a given volume. Without significant improvements in those two areas, super capacitors cannot make significant inroads against batteries.
It should also be noted that super capacitors already have better power density than chemical batteries by a wide margin, and are more than sufficient to replace I.C. engines and gasoline in that respect.

Indeed, it's the same plant in the same way that a Yorkshire Terrier is the same animal as a Golden Retriever. Only through selective breeding did they reduce the THC concentrations low enough that the plants couldn't be practically used for psychoactive contents.
Someone flopped a steamer in the gene pool.
And when you make them into hot dogs, they all taste relatively the same.
The wiki link to "bast" refers to a dozen species that produce basts, including flax, wisteria, mulberry, and kudzu.
Is there a reason to go for hemp in particular, aside from the usual hemp-will-solve-everything? Flax is also produced in industrial quantities. TFA doesn't mention why they chose hemp bast.
Look, I'm all for legalized weed and hate the propaganda that makes it out as a devil drug, but I'm not any bigger fan of exaggerations about the wonders of hemp. At least on this web site, it would be nice to look at actual data, rather than who can out-propagandize everybody else.
They're the same plant. Hemp (both industrial and medicinal strains) were banned because:
a) there was hysteria over growing opium addiction, and the confusion about hashish (which was, at the time, a foreign and relatively unknown substance) lead some people to believe it was a form of opium
b) it threatened the massive paper and fibre industries
c) the 'top' media entrepreneurs at the time had investments in (b) and used their media empires to stoke the fear surrounding (a) to see hemp banned in the US alongside opium; then other countries followed because of the pressure put upon them by the US government
A classic story of capital triumphing over Good Things.
And since all this process requires are the stalks, then for all intents and purposes, yes. It is the same plant.
The buds, which have recreational and medicinal uses aren't being used. The key word there is lignin. They're using the long, fiberous material not the buds.
And just like those two Canis Lupus Familiaris any two Cannabis Sativa plants will breed and are thus one species.
Actually hemp production focused far more on producing good fiber than reducing THC content. At least until very recently. The THC reduction was just a side effect no one cared about, not until we started having modern drug laws anyway.
And when you make them into hot dogs, they all taste relatively the same.
Yeah, people get the munchies when they are stoned.
Don't look at your dog that way when you get high.
Dogs can sense when someone is thinking about eating them.

Entire? Not quite. It's been discussed here plenty for you to already know that there are states that have enacted legalization.
Colorado even just recently approved the regulatory structure for stores selling pot products.
You may certainly continue to believe what you want to believe, it's just fictional.

For all I know this is valid scientific research. But I can't even be bothered to find out because potheads have stigmatized hemp. "Dude, do you know hemp is 85% more efficient biomass than bacon?" "You know that hemp fibers can be turned into inferior yet expensive paper, right?" "Hemp-o-lene, it's either hemp biofuel or something you jump on." Which all are quite obviously thin excuses to grow more "medicinal"* hemp.
And hemp is a pretty great material, but every time I see an article that talks about a new industrial use I can't help thinking it comes from the same people who giggle when they hear "420" and snerk when they mention how they're into 'hydroponics'.
Seriously folks, if you want me to take you (hemp or pot smokers) seriously you need to clean up your game. Don't smoke a bowl on April 20th, instead bring to my attention how we really don't know the medical properties of cannabis because of government overregulation (or whatever, anything that has real promise to someone who has no interest in smoking pot.)
*Medicine is sold at drug stores, not in shadowy places with a bouncer at the door and punny names like "Grass Roots Clinic" or "Foggy Daze Dispensary".
Pot. Is there anything it can't do? /might be a little high right now actually

Plot twist: Marijuana summons Cthulhu to destroy the world. The "assholes" knew this whole time, they genuinely were acting in our best interests. Had they told us the reason why they wanted it illegal, we'd laugh them off. They were hoping we could get to the point where we could fight back, sometime in 2050, but no, the dirty hippies won and we were no match for the ancient ones.
Yeah, but if you get such a store, you'll lose your KFC.
It's an unfair trade.

On the contrary, the real reason marijuana is illegal is due to the huge benefits of hemp and relative cheapness/ease of growth. Corporate lobbying strikes again (or struck, back in the 1930's). Do some research if you're completely lost on what I'm referring to here (I'm sure the majority are).
Agreed.
As a Christian I am constantly appalled by idiots who cherry-pick verses out of context to support their prejudices. I don't think having a good time at a party (or at the wedding you referred to) is equivalent to being a drunkard. People who take verses to support their own biases, ignoring the context and what is actually being said make all Christians look bad.
The Christian Right is Neither (Christian nor right). See: Matthew 23, Matthew 25, Ezekiel 16:48-50
So since William Randolph Hearst demonized Hemp and forever tied to to Pot, it's been illegal to grow in the USA. You do realize that in most of the free world, you can walk into a grocery store and still buy products made from Coca leaf?
And yet in the "land of the free" almost everything is banned. Except guns. And you need those in case the government "takes away your rights". I hope you see the tremendous irony there.
If telephones are outlawed, then only outlaws will have telephones.
Pot. Is there anything it can't do? /might be a little high right now actually
It can't call the kettle black.
You kind of glossed over the big issue (B). The issue was Dupont.(concerning hemp not marihuana) Dupont had just created the synthetic fibre. Dupont did not want competition. The same can be said for hurst and his wood pulp making venture. The fact that you can make as much paper on 1 acre of land with hemp yearly as it would take 30 acres of land a cycle of 20 years to produce the same amount of paper.
This is the big reason it was banned. Now they also used the "black will rape white women" and "lazy mexicans smoke pot" as an excuse in the media (re: reefer madness for a good laugh. It is a funny movie minus the fact that they actually believed it to be true when made)
have you seen my sig? there are many others like it but none that are the same

"Flyin' in just a sweet place,
Never been known to fail..."
LOL True. It can't do that.
Anyhow... I'm THAT guy. The guy that smokes and doesn't actually think that legalizing it will solve all the world's problems. I'm in favor of legalization and think that it would help solve *some* problems however. It is legal for me to smoke and grow now but I still think it should be legalized and subject to reasonable taxation.
In case you're curious, I got my card because I have issues sleeping. I still have plenty of trouble sleeping but now I get to smoke weed legally. It hasn't helped though it does ease the paranoia to imbibe legally.
I figure it would help lower budgets and stop us from incarcerating people for that particular victimless crime.
"So long and thanks for all the fish."
Legalizing marijuana and hemp would actually solve a lot of problems though. As you say we could stop locking all these people up for a mostly harmless activity. But it would also open up hemp as an industrial resource. As I'm sure you know hemp is useful for all kinds of stuff from textiles to paper to seed oil and meal. It grows fast and has little need for pesticides. But we can't grow it domestically because of our stupid prohibition.
