IBM predicts smarter buildings, transportation, water systems, medical  will impact cities...

Casting one’s eye into a crystal ball is a risky undertaking that can leave the forecaster as visionary or fool – particularly if they are short term predictions that can easily be checked. But that hasn’t deterred the soothsayers at IBM coming up with their fourth annual “Next 5 in 5” list of innovations that will impact our lives in the next five years. Based on market and societal trends as well as emerging technologies, the latest list focuses on innovations that have the potential to change how people live, work and play in our burgeoning cities.  Read More

On charge - the fast charger is claimed to replenish the Lithium-ion batteries to 80 perce...

As Mitsubishi's iMiev electric cars become available to the public next year, the UK will be the first to benefit from technology that will see the Lithium-ion batteries recharged to 80 percent capacity in just 30 minutes. Mitsubishi UK will be the first company in Europe to showcase the city car's fast charging capabilities.  Read More

Researcher Bing Hu paints a small square of ordinary paper with an ink that will deposit n...

By dipping an ordinary piece of paper into ink infused with carbon nanotubes and silver nanowires, scientists have been able to create a low-cost battery or supercapacitor that is ultra-lightweight, bendable and very durable. The paper can be crumpled, folded or even soaked in acidic or basic solutions and still will work.  Read More

Window washers may need to look for alternative employment thanks to the new nano-material...

While attempting to find a cure for Alzheimer’s disease researchers have discovered a new nanomaterial that can repel dust and water and could provide a self-cleaning coating for windows or solar panels. Unlike similar dust-busting materials that take inspiration from the surface of the lotus leaf, the new material is actually made up of molecules of peptides that “grow” to resemble small forests of grass. The coating also acts as a super-capacitor, thereby having implications for electric cars in that it could provide an energy boost to batteries.  Read More

The system developed by Professor Nocera to store energy gathered from solar panels could ...

Reports of new developments in the area of solar power are an almost daily event here at Gizmag. The main focus of research seems to be on improving the efficiency of solar cells, but others are working at developing an inexpensive method of locally storing the energy generated by solar systems. Because society relies on a continuous energy supply and solar energy is diurnal, storage systems are integral to what some see as an inevitable move towards the era of “personalized solar energy”, in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities.  Read More

Two artificial cells that can act as a tiny battery
 (Credit: NIST)

Synthetic cells that act as a battery could one day be used to power nanotech devices. Scientists from Yale University and the National Institute of Standards and Technology (NIST) created a very simple cell model in order to study the way certain real cells generate electric voltages. In the process they produced a minute working battery that converts chemical energy into electrical energy at an efficiency of about 10 per cent - a figure that's high enough to make cell batteries a practical alternative as a nano power source.  Read More

Venom Eco Alkaline batteries are the world's first certified carbon neutral batteries

A new range of batteries from Venom is free of mercury, cadmium and lead, and has been certified carbon neutral by Carbonfund.org. The Eco Alkaline batteries were certified carbon neutral after a detailed product life-cycle assessment of carbon emissions. As part of a carbon neutral project, Venom is supporting the Return to Forest Project which is helping to reforest Nicaragua's Pacific coast.  Read More

Energizer 4X and 8X Lithium batteries

These days, if you go looking for batteries you're likely to find a range of products with some fairly bold claims on their packaging. Standard AA alkaline batteries are the least expensive and have been around for decades, but now there's a bunch of other choices for single use batteries that are marketed as better choices for "digital" devices than the "copper top" or store branded staples we've used for years. Among the newest of these is Energizer's Advanced Lithium and Ultimate Lithium single use batteries.  Read More

A close up of the solar cell created by the Trinity team - the dark hair can clearly be se...

Debate is good. Debate is healthy. Debate is currently raging after an article recently appeared on the UK's Daily Mail website announcing a revolutionary solar cell that's made using human hair. A group of teenage students from Nepal claim to have replaced expensive doped silicon used in conventional solar panels with cheap and readily available human hair to produce a cell capable of generating 9V (18W) of electricity. Curiosity got the better of Gizmag's Paul Ridden, who contacted one of the team to find out more.  Read More

The test vehicle into which researchers are integrating a redox flow battery

German researchers say a new type of electric vehicle battery that runs on electrolyte fluid can be recharged as easily as refilling a petrol tank. When the redox flow rechargeable batteries are low, the discharged electrolyte fluid can simply be exchanged at the gas station for recharged fluid.  Read More
