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.
There are few details about the electric drivetrain in Motive Industries' Kestrel, but the car's designer Darren McKeage explained that the four-seat compact vehicle was designed around some core ideals:
Top 10 Cannabis Studies the Government Wished it Had Never Funded
10) MARIJUANA USE HAS NO EFFECT ON MORTALITY:
A massive study of California HMO members funded by the National Institute on Drug Abuse (NIDA) found marijuana use caused no significant increase in mortality. Tobacco use was associated with increased risk of death. Sidney, S et al. Marijuana Use and Mortality. American Journal of Public Health. Vol. 87 No. 4, April 1997. p. 585-590. Sept. 2002.

9) HEAVY MARIJUANA USE AS A YOUNG ADULT WON’T RUIN YOUR LIFE:
Veterans Affairs scientists looked at whether heavy marijuana use as a young adult caused long-term problems later, studying identical twins in which one twin had been a heavy marijuana user for a year or longer but had stopped at least one month before the study, while the second twin had used marijuana no more than five times ever. Marijuana use had no significant impact on physical or mental health care utilization, health-related quality of life, or current socio-demographic characteristics. Eisen SE et al.

8) THE “GATEWAY EFFECT” MAY BE A MIRAGE:
Marijuana is often called a “gateway drug” by supporters of prohibition, who point to statistical “associations” indicating that persons who use marijuana are more likely to eventually try hard drugs than those who never use marijuana – implying that marijuana use somehow causes hard drug use. But a model developed by RAND Corp. researcher Andrew Morral demonstrates that these associations can be explained “without requiring a gateway effect.” More likely, this federally funded study suggests, some people simply have an underlying propensity to try drugs, and start with what’s most readily available.
