The Signa bike runs on fuel cells . But in preference to having to carry hydrogen next on your butt, it uses a new clever safe method: It runs on cells filled with a sand-like powder. You simply ought to add water.
The powder is sodium silicide, an inert, safe substance that’s not dangerous at all. While you add water to the cell, hydrogen gas is produced, which generates electricity. The cells are 1.5 pounds and they’re hot-swappable, because of this that you can plug another right in once you reach its maximum 30-mile run.
According to the company, they’re working in making this cells more powerful, to be able to be integrated in cars. [ Wired ]
