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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
