Self-charging battery stretches over skin to power wearables

While we've seen promising prototypes of computers that conform to the contours of human wrists and forearms, the technology isn't quite ready for mainstream adoption yet. But this hasn't stopped one forward-thinking team of researchers from coming up with a new way to power these wearable electronics, developing a soft, millimeter-scale battery that can be stretched over the skin like a band-aid.Read More

Nissan EVs to join the grid in UK trial

Nissan has partnered with power company Enel to launch a pilot program in the UK allowing electric vehicle owners to sell energy from their car batteries back into the grid. As well as allowing EV drivers to make a bit of extra cash from their cars, Nissan sees the program as the first step towards using cars as mobile energy hubs. The announcement came alongside the launch of the xStorage home battery, which uses recycled Leaf batteries for home energy storage.Read More

Urine-powered battery offers cheap energy source

When most people think of bacteria and urine together, chances are good they think of a not-so-pleasant infection. For researchers at the University of Bath however, putting these two thoughts together led to the development of a battery that could harness "pee power" to bring energy to parts of the world that might not otherwise have access to it.Read More

Daimler electric trucks to deliver cost savings in Stuttgart

As electric cars careen towards the mainstream, the world's truck manufacturers are also working to make the most of battery power to cut local CO2 emissions and running costs. Daimler is attempting to demonstrate the benefits of moving to electric trucks by running four Fuso E-Cell trucks in Stuttgart, where they'll deal with everything from road construction to furniture delivery.Read More

Experimental battery charges and recharges via bacteria

Inside your body, the wrong kind of bacteria can sap you of energy. Inside a battery, however, it turns out that the right kind of bacteria can cause an energy boost that might be able to help power our lives. That's the finding from researchers in the Netherlands, who've just developed a bacteria-based battery that they were able to charge and discharge 15 times in a row.

The rise of Tesla: From boutique to big time?

Since its inception in 2003, Tesla has pushed the development of electric cars at a rate unmatched by any mainstream manufacturer. With niche cars like the Roadster and high-end electric saloons like the Model S, the Silicon Valley startup has a core following among cashed-up early adopters, but March 31 marks the date Elon Musk takes his project to a wider audience with the more affordable Model 3. So how did Tesla get here, and what challenges lie ahead?Read More

Miniature fuel cell to keep drones aloft for over an hour and phones charged for a week

Drones are being utilized in everything from parcel delivery to search and rescue, but their limited flight times are restricting their ability to travel great distances or stay for extended periods of time in the field. Simply adding more batteries, however, affects flight characteristics and reduces the load the drone can carry. To help solve this problem, researchers at the Pohang University of Science and Technology (Postech) have created a miniature fuel cell they claim not only provides enough energy to keep a drone in the sky for over an hour, but may well find applications in powering everything from smartphones to cars in the not-too-distant future.Read More

Battery anodes made from pollen are nothing to sneeze at

As our dependence on mobile devices grows and we continue the shift to electric vehicles, there is a need to not only develop better performing batteries but find more accessible and sustainable materials with which to build them. To this end, researchers have now developed an anode for lithium-ion batteries using something those with allergies certainly wouldn't miss: pollen from bees and cattails.Read More
