The article above notes a hemp car was first created by Henry Ford.
Popular Mechanics, December, 1941
Over in England it's saccharine for sugar; on the continent it's charcoal "gasogenes" in the rumble seat instead of gasoline in the tank. Here in America there's plenty of sugar, plenty of gasoline. Yet there's an industrial revolution in progress just the same, a revolution in materials that will affect every home. After twelve years of research, the Ford Motor Company has completed an experimental automobile with a plastic body. Although its design takes advantage of the properties of plastics, the streamline car does not differ greatly in appearance from its steel counterpart.
The only steel in the hand-made body is found in the tubular welded frame on which are mounted 14 plastic panels, 3/16 inch thick. Composed of a mixture of farm crops and synthetic chemicals, the plastic is reported to withstand a blow 10 times as great as steel without denting. Even the windows and windshield are of plastic. The total weight of the plastic car is about 2,000 pounds, compared with 3,000 pounds for a steel automobile of the same size. Although no hint has been given as to when plastic cars may go into production, the experimental model is pictured as a step toward materialization of Henry Ford's belief that some day he would "grow automobiles from the soil."
When Henry Ford recently unveiled his plastic car, result of 12 years of research, he gave the world a glimpse of the automobile of tomorrow, its tough panels molded under hydraulic pressure of 1,500 pounds per square inch from a recipe that calls for 70 percent ofcellulose fibers from wheat straw, hemp and sisal plus 30 percent resin binder. The only steel in the car is its tubular welded frame. The plastic car weighs a ton, 1,000 pounds lighter than a comparable steel car. Manufacturers are already taking a low-priced plastic car to test the public's taste by 1943.

Popular Mechanics, February, 1938. Hemp: The New Billion Dollar Crop
The natural materials in hemp make it an economical source of pulp for any grade of paper manufactured, and the high percentage of alpha cellulose promises an unlimited supply of raw material for the thousands of cellulose products our chemists have developed.
It is generally believed that all linen is produced from flax. Actually, the majority comes from hemp--authorities estimate that more than half of our imported linen fabrics are manufactured from hemp fiber. Another misconception is that burlap is made from hemp. Actually, its source is usually jute, and practically all of the burlap we use is woven by laborers in India who receive only four cents a day. Binder twine is usually made from sisal which comes from Yucatan and East Africa.
All of these products, now imported, can be produced from home- grown hemp. Fish nets, bow strings, canvas, strong rope, overalls, damask tablecloths, fine linen garments, towels, bed linen and thousands of other everyday items can be grown on American farms.
Our imports of foreign fabrics and fibers average about $200,000,000 per year; in raw fibers alone we imported over $50,000,000 in the first six months of 1937. All of this income can be made available for Americans.
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.
