I've never seen that site tho I have seen YouTube vids of the hemp car before.
the car reminds me of a PT Cruiser.
Speaking of Popular Mechanics, after prohibition for cannabis went into effect, people didn't realize that the Hearst branded "marihuana, assassin of youth" was the same plant as hemp - and Popular Mechanics published this article a year after the cannabis smear campaign by Hearst (paper pulp), DuPont (petrol/nylon) and Anslinger (criminal profit) about the "new billion dollar industry."
oops. they didn't realize the coming billion dollar industries were going to be prison farms, deforestation and oil wars, not hemp fields.

Hemp is the standard fiber of the world. It has great tensile strength and durability. It is used to produce more than 5,000 textile products, ranging from rope to fine laces, and the woody "hurds" remaining after the fiber has been removed contain more than seventy-seven per cent cellulose, and can be used to produce more than 25,000 products, ranging from dynamite to Cellophane.
Machines now in service in Texas, Illinois, Minnesota and other states are producing fiber at a manufacturing cost of half a cent a pound, and are finding a profitable market for the rest of the stalk. Machine operators are making a good profit in competition with coolie-produced foreign fiber while paying farmers fifteen dollars a ton for hemp as it comes from the field.
From the farmers' point of view, hemp is an easy crop to grow and will yield from three to six tons per acre on any land that will grow corn, wheat, or oats. It has a short growing season, so that it can be planted after other crops are in. It can be grown in any state of the union. The long roots penetrate and break the soil to leave it in perfect condition for the next year's crop. The dense shock of leaves, eight to twelve feet above the ground, chokes out weeds. Two successive crops are enough to reclaim land that has been abandoned because of Canadian thistles or quack grass.
...The paper industry offers even greater possibilities. As an industry it amounts to over $1,000,000,000 a year, and of that eighty per cent is imported. But hemp will produce every grade of paper, and government figures estimate that 10,000 acres devoted to hemp will produce as much paper as 40,000 acres of average pulp land.
The reason hemp is a great paper product is the same reason it's great for car bodies - the long, strong fibers and cellulose.
