The March 2011 issue of Popular Science, on page 40 of their "Headlines, Automotive" section, describes the "first road-ready hemp-mobile". It is the Kestrel, a three-door hatchback, which is made of a "hemp composite as strong as the fiberglass in boats, yet incredibly lightweight", says Nathan Armstrong, the president of Motive Industries, the Kestrel's manufacturer. The article says that, while a similarly sized Ford Fusion weighs 3,720 pounds, the Kestrel will be just 2,500 pounds, including the battery and electric motor which makes it go. They claim the lower weight will increase the car's range by 25 to 30 percent. They expect the price of the vehicle to be around $25,000 - due to the cheap price of hemp.

To make the hemp composite, hemp stalks are combed and rolled into a mat that is infused with a polymer resin. "The hemp makes the biocomposite's flexibility similar to the carbon fiber used in race cars". Hemp is said to grow fast and "Motive Industries plans to have thousands of its hemp-mobiles on the road by next year". Now let me see, where have I heard a statement like that before? ;)

When the car wears out I wonder if it can be recycled into something that you can smoke? :cool:

interesting... There's a guy here in Boston making bamboo bicycles, we've talked about an electric version: http://erbacycles.com/

Henry Ford advocated industrial adoption of hemp both for the production of ethanol and the use of hemp fiber in structural composites.

It's a shame that industrial hemp isn't legal. Or any hemp for that matter. :p

stuff grows like a... weed... :D

"Hemp is one of the faster growing biomasses known, producing up to 25 tonnes of dry matter per hectare per year. A normal average yield in large scale modern agriculture is about 2.5-3.5 t/ac (air dry stem yields of dry, retted stalks per acre at 12% moisture). Approximately one tonne of bast fiber and 2-3 tonnes of core material can be decorticated from 3-4 tonnes of good quality, dry retted straw."

The article mentioned Henry Ford's link to hemp, but this is apparently the first (proposed) production car to actually use the material in the bodywork.

Now, how about turning the material into ethanol for fuel, instead of using corn?
