Although just a student concept for now, the “iSlide” concept by Ofir Tal combines the gyroscopic self-balancing of the Segway with the size and nimbleness of a skateboard.
[iSlide] utilizes a hydrogen fuel cell and onboard gyroscope to attain speeds of around 15 kph. Described as a mix of snowboarding and skateboarding, the iSlide’s motion is controlled by leaning forwards (to accelerate) and backwards (to slow down).
Somehow I doubt Mr. Tal has a hydrogen fuel cell inside his prototype; in fact, I wonder if this thing actually works at all.
Nevertheless, the likelihood of someone seeing me on the iSlide is about ten times greater than seeing me on a Segway, which puts it just over the “only if I were really drunk” mark but just shy of the “trying to impress a girl” threshold. (“Really drunk trying to impress a girl” does not factor in this scale, as that is a Boolean value.)
