Sounds interesting - a bit light on the technical details though.

A bit more detail here. Looks like a cartridge of the reactive material extends the battery range by 40 miles. I wonder can you stop the reaction and save the cartridge for later use?

Technical details on the 'Stable' Sodium Silicide here.

I can't find anything on the fuel cell used. I didn't think they were able to produce enough current for a size and weight practical enough for a bike, though I'm sure things have move on since I last looked.
