Are you looking for ways to charge your electronic devices while out on the water? There are many ways to do this already but how about a way that is environmentally friendly and only requires you to add water? This is the idea behind SiGNa Chemistry’s PowerTrekk – a mini hydrogen fuel cell that can recharge small devices. It works with cell phones, iPods, GPS systems, cameras and PDAs.

Michael Lefenfeld is a powerful thinker. You can see it in his eyes and the expression on his face. And he has a knack for turning a creative idea into reality. One of Lefenfeld’s best ideas so far is figuring out a way to make user-friendly alkali metals for large-scale chemical reactions. His discovery led to the formation of New York City-based SiGNa Chemistry, for which he now serves as president and chief executive officer.

Ah, the great outdoors. There’s no better way to experience the fresh air, the singing birds, and the perfectly toasted marshmallow than by camping. Sleeping under the starry skies, cooking what you can catch, and living life like pioneers can be refreshing, and if you can check in on Facebook while you’re doing it, all the better.

Hydrogen and Kinetic Energy Will Keep Phones Ringing

admin — Thu, 26 Jan 2012 20:26:09 +0000

Carmakers learned years ago it’s not easy to make a practical hydrogen fuel cell. Yet hydrogen fuel cells do work, and they’re greener than batteries. So how about using a mini hydrogen fuel cell to recharge something small—like your mobile phone battery?

That’s the idea behind SiGNa Chemistry’s PowerTrekk, demo’d at the recent Consumer Electronics Show in Las Vegas. The device is filled with a powdery substance known as sodium silicide that produces hydrogen gas in the presence of water. It has the same recharge power as six AA batteries, minus the heavy metals and toxic chemicals.

PowerTrekk and PowerBag: That’s two separate companies — but with a common goal: Keeping your vastly expanding bandolier of gadgets up and running wherever you go, however long you’re going. Swedish company PowerTrekk’s novel fuel cell recharger (powered by technology from New York’s SIGNa Chemistry) gives you all-day charge with just a hockey-puck shaped disc and a few fluid ounces of water. PowerBag is less exotic but — in some ways — more immediately useful: It’s a bag, with power. Attachments (full-size, mini and micro USB, as well as iDevice) allow you to connect up to four devices to a heavy-duty battery that neatly sockets into the bag. To recharge the battery (and any attached devices), just plug the whole bag into the wall. A lifesaver.

Portable fuel cells arrive: Will your next battery be a water fountain?

Batteries and chargers are the bane of a high-tech lifestyle. For each new device there is usually a new size battery, a new charger, and a new set of concerns about battery life. And then comes the quest for an AC power outlet to fire them all up. For years the industry has been searching for some type of “holy grail” that would allow road warriors to travel freely without being slaves to power sockets and backup batteries. Solar was the first candidate, but portable solar cells have limited power output, and of course only work when the sun is shining.

Stockholm techies use water to charge mobile phones

A Swedish company headquartered in Stockholm has figured out how to power smartphones using a system that includes some water, a tray, a little round container, and an eyeglass case styled cover. The company, myFC, is introducing its PowerTrekk system to Americans at the CES show in Vegas. PowerTrekk describes its charger as a pocket size, lightweight gizmo for users “who spend time away from the electricity grid.” Translation: If you are hiking over the weekend with no Starbucks or friend’s flat in sight, your phone can still get charged.
