Plastic Made From Fruit Rivals Kevlar In Strength 181

jldailey618 writes "A group of scientists from Sao Paulo State University developed a way to use the nanocellulose fibers from bananas, pineapples, and other fruits to create incredibly strong, lightweight plastics. The plastic is up to four times stronger and 30 percent lighter than petroleum-based plastics, and it rivals Kevlar — the material used in bullet proof vests — in strength."

    The last time someone tried to compete with DuPont with a cheap and available material, they lobbied congress to ban the material, which they did.

    I for one do not wish to have bananas, pineapples, or any other fruit be classified as a schedule I controlled substance.

    Is strong really the correct term to use here? People think of kevlar being strong because it's used to stop bullets, but they're really completely wrong. Sure, it's stronger than steel, but not as strong as fiberglass or carbon fiber. You use kevlar in armor because it is tough, toughness being defined by the area under the stress/strain curve. It can absorb more energy than any other material. If it's as strong as kevlar, well then there are plenty of other natural and synthetic fibers that are just as capable, and this is nothing impressive. If it's as tough as kevlar, well then there is something of significant interest here.

    The material they banned was industrial hemp.

    Technically, no. Your pothead buddy claimed that DuPont got hemp banned - a favorite lie of hippies and other assorted idiots. Also, industrial hemp isn't technically banned, even in the US - you can get a permit to grow it (it's just really hard to get one).

    They made it illegal to grow it under the guise of going after marijuana. Even though you could set an entire field of industrial hemp on fire and not get high they still managed to get it and marijuana covered under the same law and banned.

    That's a bit of a red-herring. Nobody ever suggested you could smoke hemp - the issue was that hemp fields made the ideal hiding spot for pot cultivation. Right now they get hidden in corn-fields and such, but tend to be relatively easy to spot from the air; you could grow millions of dollars worth of marijuana in a hemp field, and nobody would know unless they did a detailed ground-level inspection.

    Note that I'm generally in favor of legalizing marijuana - I'm just apposed to lies and distortions.

    Not sure what planet your from, but nothing is banned.

    It's a controlled substance, hence you can get a license to grow it. Industrial hemp, or medicial marijuana. I repeat for you, a non stoner, who don't know exactly what you are talking about, NOTHING GOT BANNED.

    When they got "industrial hemp" and "medical marijuana" changed into a controlled substance, they (being the corporation who just got the chemical formula's from germany, as part of WWI reparitians.), because plastic would NOT compete with the low cost and usuablility of hemp at the time. They purposely made it seem that it was marijuana they were trying to get contolled, when it was actually hemp they wanted out of the picture.

    You an find all the info, include actual copies of official documents on how this happened here: http://www.jackherer.com/thebook/ [jackherer.com]

    Here's online hosting of the book: http://www.onlinepot.org/grow/jackherer.htm [onlinepot.org]

    I have nothing to do with those sites or the book. I'm just an american who's tired of the lies and bullshit. And corporation being treated like they are the rich, since they rarely, and i mean, rarely get in trouble for the shit they do.

    Oh, and i like to point out, yes, it was Dupont. So those hippies and other idiots who you think lie (probably because they are stoners), aren't. In fact, your the idiot now, but then, we knew that from your post. thanks for letting me share the real story.
