Add Just a Bit of Water To Tiny Canisters And Power Fuel Cells on the Go

SiGNa's Portable Canisters Just add water. SiGNa Chemistry Inc. Even in places where potable drinking water is scarce, some kind of water is ofter obtainable--even if it's the stuff that usually ends up in the latrine. SiGNa Chemistry Inc. is taking advantage of the hydrogen in that water with a new portable canister that can power a small fuel cell to juice up mobile electronics on the go. Think of it as fuel for a fuel cell; just add water. This kind of technology isn't entirely novel. We've written about magnesium-based power packs designed for the military that can generate power from saltwater (or a GI's urine if needs be). And SiGNa itself has integrated its own sodium silicide technology into an electric-assist bike engine. But now the tech is being reduced to a canister that could fit in a pocketable fuel cell that allows users to recharge on the go. SiGNa isn't...
