One of the makers that we encountered setting up of the Maker Faire Detroit on Friday afternoon was Douglas Amick. Amick was unloading the A2, a three-wheeled, battery-powered, wind-assisted tandem-two-seater. The A2 was originally built by Amick's late father James. The elder Amick devised the aerodynamic arch on the rear of the vehicle which is claimed to help propel the vehicle forward in cross-winds. Apparently, airflow coming in at an angle to the vehicle will swirl around as it passes through the arch actually applying force to the rear of the vehicle giving it some boost. We'll have to check with some contacts with aerodynamic expertise on the veracity of this claim, but the vehicle is kind of cool looking. Apparently, it originally had aluminum air batteries installed but they are no longer functional.
