A study by IBM researchers has revealed that many discarded laptop batteries have the potential to provide enough power to keep the lights running in homes in poorer countries around the world. The India-based team conducted a small study to test the viability of the idea, with work now focused on streamlining a prototype system.  Read More

The Wind Tree turbine is designed to generate power from low-speed winds

Generally speaking, the peculiar appearance of wind turbines coupled with the fact they perform better when up high and out in the open sees them banished to uninhabited countryside, or even out to sea. But a French entrepreneur believes that sculpting them in the form of an artificial tree could lead to wider adoption in urban centers, making use of low winds that circulate around buildings and streets.  Read More

Two views of the X Mini

Back in 2012, Gizmag looked at LiquidPiston’s X2 rotary engine. The compact, low-vibration, high-efficiency 70 bhp and 40 bhp compression ignition engine was something of a sensation. Now the company is back with the 70 cc X Mini engine, which LiquidPiston’s President and Co-Founder, Dr Alexander Shkolnik unveiled on Wednesday at the SAE International/JSAE 2014 Small Engine Technology Conference in Pisa, Italy.  Read More

Lockheed sees its compact fusion reactor as ready in 10 years

Fusion reactors are a bit like buses; you wait forever for one, then two come along at once. No sooner does the University of Washington announce that it’s working on a breakthrough compact fusion reactor (CFR) than Lockheed Martin says that its Revolutionary Technology Programs unit, AKA the Skunk Works, in Palmdale, California has one that could be ready for market within ten years.  Read More

Ampy is also pocketable at 3 inches square

Kinetic chargers have been around for a few years, but have typically been big and bulky. Ampy is much smaller and fashionable enough to wear around.  Read More

By playing around with materials, researchers have reduced the operating temperature of an...

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.  Read More

Samsung's Power Sharing Cable lets users easily share charge between their devices

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

Canadian researchers have developed a chin strap made from piezoelectric fibre composites ...

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

Google and the IEEE are offering a US$1 million prize in their Little Box challenge

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.  Read More

Go Kin packs are designed to generate energy from your walk

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
