The VOTO fuel-cell charger gets power from cooking fires

Just because someone is getting close to nature doesn't necessarily mean they need to ditch their smartphone. However, keeping a device charged while in the great outdoors is not always the easiest thing to do. After all, those trees don't come equipped with power outlets. We've already seen the BioLite stove that generates its own power. A new product called VOTO performs a similar function, but with any cooking fire.  Read More

Lockheed Martin and Reignwood Group plan to develop a 10 MW prototype OTEC pilot plant off...

Lockheed Martin has been getting its feet wet in the renewable energy game for some time. In the 1970s it helped build the world’s first successful floating Ocean Thermal Energy Conversion (OTEC) system that generated net power, and in 2009 it was awarded a contract to develop an OTEC pilot plant in Hawaii. That project has apparently been canceled but the company has now shifted its OTEC sights westward by teaming up with Hong Kong-based Reignwood Group to co-develop a pilot plant that will be built off the coast of southern China.  Read More

Every step counts at the Paris Marathon

While the term "electrifying" can sometimes be used to describe breathtaking performance in sports, it's not often you'll find it used for marathon runners. Yet, that's precisely the word I'd use to describe this year's Paris Marathon, which took place on Sunday April 7. You see, as the feet of almost 40,000 runners hit a 25-meter (82-foot) installation of special tiles at the beginning of the 26-mile (42-km) course, kinetic energy was harvested and turned into usable electricity.  Read More

The 'artificial leaf' created by Daniel G. Nocera, Ph.D. and his team now has self-healing...

Back in 2011, scientists reported the creation of the “world’s first practical artificial leaf” that mimics the ability of real leaves to produce energy from sunlight and water. Touted as a potentially inexpensive source of electricity for those in developing countries and remote areas, the leaf’s creators have now given it a capability that would be especially beneficial in such environments – the ability to self heal and therefore produce energy from dirty water.  Read More

Using the hand crank of the SOSCharger to provide power to an iPhone

When there's a natural disaster or bad storm, power outages are almost guaranteed. This can be an annoyance during a minor storm, but during a more serious disaster, a lack of power can mean not being able to get in touch with friends, loved ones, and in the worst of situations, help. The SOSCharger is designed to combat this by allowing users to keep their phone charged with a simple hand crank.  Read More

Some of Fraunhofer's printed thermoelectric generators, wrapped around a sample component

Thermoelectric materials, putting it simply, are able to generate electricity via differences in temperature. If thermoelectric felt were used to make a jacket, for instance, it could generate a current using the temperature gradient between the warm interior and cold exterior of the garment. Like many such promising technologies, however, the cost of thermoelectrics is something of an issue ... although thanks to a new process developed at Germany’s Fraunhofer Institute for Material and Beam Technology, that might not be the case for much longer.  Read More

Dutch researchers have developed the EWICON, a bladeless windmill with no moving parts tha...

Wind energy may be one of the more sustainable sources of power available, but the spinning blades of conventional wind turbines require regular maintenance and have attracted criticism from bird lovers. That might explain why we've seen wind turbine prototypes that enclose the blades in a chamber or replace them entirely with a disc-like system. But researchers in the Netherlands set out to eliminate the need for a mechanical component entirely and created the EWICON, a bladeless wind turbine with no moving parts that produces electricity using charged water droplets.  Read More

The Wattio system is a four-component package comprised of a POD, THERMIC, GATE and BAT (I...

Here at Gizmag we've featured a variety of home energy management devices, and the latest solution is an offering from Spanish startup, Wattio. The SmartHome 360º is a home energy monitoring and control system that can be managed through a smartphone, tablet or PC using the Wattio Gateway software. The system's four components are capable of communicating with each other and subsequently with the Wattio software applications and cloud service, to provide comprehensive energy management capability throughout the home.  Read More

The Shams 1 concentrated solar power plant covers and area of 2.5 square km (1 sq mile)

Thanks to its low latitude and low percentage of cloudy days, the United Arab Emirates (UAE) is an ideal location for capturing solar energy. So it’s no surprise to see the world’s largest operating concentrated solar power (CSP) has launched in the sun-soaked Middle Eastern country. Officially inaugurated this week by UAE President and Ruler of Abu Dhabi, Sheikh Khalifa bin Zayed Al Nahyan, Shams 1 is a 100 MW CSP that will power 20,000 UAE homes.  Read More

In November 2009, Norwegian state owned electricity company Statkraft opened the world’s first osmotic power plant prototype, which generates electricity from the difference in the salt concentration between river water and sea water. While osmotic power is a clean, renewable energy source, its commercial use has been limited due to the low generating capacities offered by current technology – the Statkraft plant, for example, has a capacity of about 4 kW. Now researchers have discovered a new way to harness osmotic power that they claim would enable a 1 m2 (10.7 sq. ft.) membrane to have the same 4 kW capacity as the entire Statkraft plant.  Read More
