Unlike the world’s first maglev train, China’s new hydrogen-electric train has a built-in hydrogen power system that enables it to travel 373-miles on a single charge. This is no bullet train though, as it has a maximum speed of 99.4 mph, which is plenty fast for urban transport. The powertrain consists of a hydrogen fuel cell and supercapacitor, rather than a traditional catenary power supply system.

Sailboat Solar-Powered Floating Home
If the U-Boat Worx NEMO 2 personal submarine is a little too pricey for your budget, you could always buy a sailboat for $23,000 and transform it into a solar-powered floating home. Journeyman and sailor Daniel did just that after he picked up a 1984 Beneteau Idylle sailboat. It may not be the most luxurious of living space, but this sailboat does offer him the opportunity the maximize the amount of time he can spend exploring off-grid.
