Vectrix hybrid scooter for commuters: Coller than the Segway
Engineers at Vectrix Corp. are working on the industry's first hybrid fuel cell/electric-powered scooter, due out in approximately 3 years. An all-electric version will be introduced within the next 18 months. Parker Hannifin has partnered with the scooter maker to develop the direct methanol fuel cell, which will operate continuously at its rated power output until the battery pack is fully charged, then it will shut off. "A big advantage is that drivers won't have to rely on a charging infrastructure. All that's required is methanol and water—the same thing you have in your windshield washer fluid," says Craig Maxwell, VP of Innovation and Technology at Parker Hannifin. Engineers say the scooter's performance will be comparable to other vehicles powered by two-stroke, 250cc engines. Target acceleration is 0 to 50 kph in 4 seconds, as experienced by Maxwell's test ride on an early prototype: "Being a guy, I didn't want to hang on to the engineer driving the scooter, so I thought I'd just hang on to the scooter. When we started up, I nearly flew off the back end of the thing," he recalls. The scooter is targeted at the commuter market and will retail for $5,500.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
