The HydroFILL allows users to generate their own hydrogen and recharge the company's proprietary HydroSTIK miniature hydrogen tanks themselves, rather than having to spring for new ones when expended. Those two components, combined with the HydroPAK charging dock, will allow you to use essentially water to charge a variety of devices and peripherals. No more phone wall chargers, ever!
Still, for the time being this technology won't enter your home cheaply, with the HydroFILL tank priced at $499.99 (plus an optional $649.99 solar panel if you want to go truly off the grid). But each HydroSTIK packs the juice of 1,000 AA batteries, so hardcore chargers should be able to earn that back. Plus, next time someone is over at your place and needs to charge their phone, you can say, "Oh, one sec, let me see if my personal power plant is done generating hydrogen."
