As we're faced with an increasingly large world population and ever-dwindling resources the race is on to produce cars that not only produce zero tailpipe emissions, but ones that are green to manufacture too.
But what is the ultimate material for cars? Steel is strong, but hardly light enough to make ultra-efficient vehicles. Many plastics are based on oil, and composite materials like carbon fibre are difficult and costly to manufacture and repair.
Enter the Kestrel. Designed and engineered by Motive Industries, a Canadian firm based in Alberta, the fully electric car features a body shell made of hemp--which may be better known as Cannabis Sativa L.
The hemp for the Kestrel's body is grown by Alberta Innovates Technology Futures (AITF) under license from the Canadian government.
Unlike the cannabis Californians may find available at their local medical marijuana dispensaries, hemp grown by AITF ends up on a production line, where it is turned into a composite material that has the impact resistance of fiberglass.
But unlike fiberglass, the hemp bio-composite is cheaper to produce and has fewer health risks connected with its manufacture. It is also significantly lighter than glass-based composites traditionally used in racing cars.
