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.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
