Our ability to store energy has proven a big hurdle in the adoption of renewable energies. But now a team of researchers from MIT has developed a new all-liquid battery system that extends the life of such devices while also costing less to make, a development they say could make wind and solar energy more competitive with traditional sources of power.

Samsung’s latest smartphone accessory allows users to conveniently transfer a charge from select smartphones and tablets to any Micro USB device. It’s an interesting, if somewhat flawed idea, that highlights a change in our perception of the smartphone. Read More
In a development that could bring new meaning to the term "motor mouth," Canadian researchers have developed a chin strap capable of generating electricity from jaw movements. The team is hopeful that the strap will be able to harvest energy from common actions like eating, chewing and talking to power medical implants and wearable devices. Read More
The old saying says good things come in small packages. Google and the Institute of Electrical and Electronic Engineers (IEEE) seem to agree having launched the Little Box Challenge, an open competition with a US$1 million first prize to find innovative electronic designs to shrink power inverters down from their current bigger-than-a-bread-box size to something less than the size of a small laptop.

The market for portable gadget chargers is bulging. While grid-fed chargers like the LithiumCard are ample for use around town, things get more complicated when you venture off the grid. A new backpack cuts reliance on external power sources, harvesting energy from something much more reliably available … you. Read More
You might already be used to dropping into Starbucks to recharge your batteries, but now the ubiquitous caffeine merchant is looking to power more than just your mental energy. Today it announced plans to install wireless charging mats in every one of its US stores, meaning searching under tables and chairs for that elusive power outlet could become a thing of the past.

It could be the most important portable power plant you've never heard of. It's called the "Power Pallet" and it is essentially a combined biomass refinery and generator that fits on a single pallet and can kick out up to 20 kilowatts of electricity. Read More
Imagine using a mobile phone powered entirely by its casing, or an electric car that runs off power stored in its chassis. Researchers at Vanderbilt University have created a structural supercapacitor that could, they believe, bring this closer to reality, making batteries and power cords obsolete. The structural supercapacitor could make it possible to store energy directly in structural materials, allowing them to deliver power long-term while surviving the real-life mechanical stresses they're bound to experience.

Trike drifting, a sport that originated in New Zealand in 2009 and has since spread all around the globe, is typically the plaything of adrenaline junkies with long and winding downhill runs at their disposal. Drift-enthused DIYers have further indulged their taste for sideways movement by fixing motors to their rides, making it possible to slip and slide over flatter terrain. The Florida-based Tortuga Trikes is looking to take things up a notch, whacking a 6.5 hp (4.8 kW) motor on the back to bring the hobby a little closer to a drift car experience. Read More
The most frightening part of a tsunami hitting a nuclear power plant is what comes after – radioactive leaks that contaminate the water around the plant are exceedingly difficult to contain. The clean up of the radioactive water around the Fukushima Daiichi nuclear plant in Japan, which was struck by a tsunami in 2011, is expected to take decades. MIT researchers have come up with an alternative; they propose building floating nuclear plants, far enough offshore to simply ride out a tsunami and emerge unscathed. Read More
