I learned of this nifty little machine today. It's called the Zero Motorcycle. "Zero" for the zero emissions, I guess. I think it's wonderful! Right now it can only go 40 miles on one charge, but the inventor said the battery is completely non-toxic. It's not heavy on the horsepower but the bike can smoke the tires sitting still. The "CC" designation, if it was a fuel type vehicle, would be around 250cc (according to the video). Anyway, watch the clip. It's pretty interesting. I like quiet vehicles and this may be the wave of the future.
