Hasta La Gadget!

The biggest problem with electric bicycles? All of that pesky pedaling. Thankfully, some of the world’s top engineering minds are innovating all sorts of ways to lighten that load. Like Yamaha Motors, whose new PAS CITY-X, PAS CITY-C, and PAS Compact feature amped up batteries that can be charged twice as many times as their predecessors. You’ll get somewhere from 10 to 15 miles on a charge, depending on the setting — unfortunately not quite far enough for us to ride one back home to the States. The models will hit their native country on May 20th, at ¥106,800 ($1,299) for the CITY-X and ¥103,800 ($1,262) for the City-C and City-Compact models. Between the improved battery life and all of that artificial intelligence though, these things clearly won’t have much use for us in the near future.

The company is insisting it can’t “really be interpreted as a delay” given that it’s gone from prototype to production in just 37 months, but Fisker is now saying that the first all-electric Karma luxury vehicles will delivered to their owners sometime in June or July — which you’ll notice is neither late 2010 nor the first quarter of 2011, as had been promised. Fisker’s Roger Ormisher also points out that the company did begin “limited series production” at the end of March as planned, and he says the company is “ramping up slowly to ensure absolute quality.” Is it worth the nearly $100k price tag? It certainly seems to be if you’ve got the cash to spare.

Electric vehicles may have that instant torque thing going for them, but they’re still a bit behind when it comes to giving heart palpitations to those diehard petrolheads. Hoping to change that perception, Nissan is setting up to unveil a brand new concept vehicle, dubbed the Leaf Nismo RC (that stands for Racing Competition, not “radio-controlled”), which strips the one-size-fits-all Leaf down to its constituent elements. The drivetrain is still 100 percent electric, however it’s now powering the rear wheels instead of the front, while things like the rear seats, trunk, audio system, carpeting, and navigation have been completely removed. A carbon fiber chassis helps the Nismo RC keep weight down to 2,068 pounds (938kg), equivalent to just 60 percent of the original Leaf’s heft. Yes, the Leaf is now lighter! In performance terms, you’re looking at a car that can hit 62mph within 6.85 seconds, max out the speedometer at 93mph, and last a terrifying 20 minutes under racing conditions. This prototype vehicle will debut at the upcoming New York Auto Show and will thereafter help Nissan research better aerodynamics and, presumably, slightly better energy efficiency.

You may live your life a quarter-mile at a time, but let’s face it — you still care about the environment. To that end, you’ve patiently awaited Audi’s hybrid Spyder, even with the company playing coy about electric vehicles in general. Its latest tease is a far cry from the aforesaid ghost, but the A3 e-tron — an entry-level Sportback begging to be modified — is certainly sexy in its own right. Not exactly Fast and Furious material, given that it needs 11 seconds to reach 60mph and tops out at 90mph, but still — a pair of lithium-ion batteries should give it 90-mile range per nine-hour charge. We’d take the Roadster S’ 165-mile ride if given the choice, but we’ll confess to confessing as much prior to consulting our practical side. No hard word on availability or pricing — the company likely wants it on the streets by 2013, but don’t go changing your name to Vin Battery just yet. Or Vin Anything, for that matter.

It’s been a while since we last heard about nanogenerators — you know, those insanely tiny fibers that could potentially be woven into your hoodie to juice up your smartphone. Dr. Zhong Lin Wang of the Georgia Institute of Technology has reported that he and his team of Einsteins constructed nanogenerators with enough energy to potentially power LCDs, LEDs and laser diodes by moving your various limbs. These micro-powerhouses — strands of piezoelectric zinc oxide, 1 / 500 the width of a single hair strand — can generate electrical charges when flexed or strained. Wang and his team of researchers shoved a collection of their nanogenerators into a chip 1 / 4 the size of a stamp, stacked five of them on top of one another and can pinch the stack between their fingers to generate the output of two standard AA batteries — around 3 volts. Although it’s not much, we’re super excited at this point in development — imagine how convenient to charge your phone in your pocket sans the bulky battery add-ons. And that’s only one application of this technology. Yea, we know.
