RYNO Motors' single-wheeled electric scooter is self-balancing, has a turning radius of zero when stopped, & only takes up about as much space as a folding bicycle -- so it's conceivable that commuters could bring one onto a train.
Small "plant" nearly covers the energy use of a single American home. Not much space taken up. This is probably way more than I'd need for off-grid living in a Yurt. But I could harness solar and wind power for all my electric needs.
Recently we saw the Radinn G2X, a surfboard that didn’t stop when the waves did. Now we’ve got TRACK1, an off-road electric board that doesn’t stop when the road does. The TRACK1 can beat off snow, sand, and dirt to get you wherever you need to – of course, this board also eats up the city streets too. TRACK1 gets its name from the strong, tank-like track sitting in the rear of the board.
