There are lots of ways to produce electricity. We don’t generally think about that fact because we’re seldom very far from a power outlet. But when you’re lost in the woods and your GPS device runs out of juice, an alternative to a power outlet sounds really attractive. And that seems to be what Signa Chemistry has created.

The company, working with partners, has developed a recharge system that requires just a tablespoon of water, a small metal tin the size of a snuff container and a plastic container about the size of an eyeglass case. Put all the pieces together and in about 15 seconds, you can start recharging your GPS device, phone or camera.

The system produces about the same amount of power as 4 AA batteries and will give you about 10 hours of phone battery life.
