Power dense zinc-manganese power unit as cheap as a car battery

A team of scientists working on analyzing energy flows in prototype zinc-manganese batteries have stumbled upon a new way to make these power cells much more reliable, with many more recharge cycles than the humble lead-acid car battery, but costing around the same to produce. The creators claim that the new battery could become an inexpensive, ecologically-sound alternative for storing energy from renewable sources and a high-density solution for storing excess energy from the power grid.Read More

Breitling B55 Connected watch puts smartphone at its service

Is the mobile phone threatening to kill off the wristwatch? Not if Swiss watchmaker Breitling has anything to say about it. With an apparent motto of "if you can't be 'em, then make 'em work for you," the Breitling B55 Connected combines smartwatch technology with haute horlogerie in a partnership where the phone serves the watch instead of the other way round.Read More

Tesla gearing up for release of batteries for the home

The same lithium-ion battery technology that powers Tesla’s electric vehicles will be used to develop a battery for the home, according to a statement by CEO Elon Musk during a recent conference call with analysts. The batteries would be used by homes and businesses to store excess energy generated from solar panels during the day, and drawn from at night when panels sit idle. Read More

Zcan Wireless cuts the cord on scanner mice

Hong Kong-based company Design to Innovation (DTOI) has developed what it is claiming is the world's first wireless scanner mouse. The Zcan Wireless is designed as a standard optical mouse, but does away with the cord and packs a miniaturized scanner, enabling users to instantly scan images and text. Read More

New water-based organic battery is cheap, rechargeable and eco-friendly

Lithium-ion batteries have made portable, rechargeable electronics commonplace. Unfortunately, they do have some glaring drawbacks, including heat issues, being made with rare, toxic elements, and the fact the technology doesn't scale up very well, which limits applications. A team of scientists at the University of Southern California (USC) is working on an alternative in the form of a water-based organic battery that is not only cheaper and more environmentally friendly, but also holds the potential for scaling up for use in wind and solar power plants as a means to store large amounts of energy.

Caseboard electric skateboard knows when to fold 'em

Electric skateboards can be a great way to get around town, but it's a different story when it's time to get off the board. The battery and motor that make things so cruisy when the board is underfoot have the opposite effect when its tucked under your arm. And it's not just the weight, with electric skateboards generally featuring a longboard form factor that can be unwieldy to carry. That's why Adam Riley of Epic Skateboards has developed the Caseboard, an electric skateboard that folds in half for carrying like a briefcase when not getting users from A to B.Read More

Graphene and carbon nanotubes combined to create flexible, wearable supercapacitor

An international team of researchers has developed a supercapacitor composed of graphene and carbon nanotubes that is claimed flexible enough to be woven into clothing and potentially powerful enough to offer a real alternative to batteries for use in portable devices. Capable of being charged and discharged in excess of 10,000 cycles, the new supercapacitor also promises to be significantly lighter, faster to charge, and more robust than current battery technology.
