Ability to charge electronic devices through Wi-Fi is here

Imagine being in a room and charging your smartphone or other mobile device wireless, simply by connecting to Wi-Fi? This is will soon be possible thanks to Disney Research.

Bacteria fed synthetic iron become electrical generators

Some bacteria are electrogenic, meaning they can generate current as part of their metabolism. Researchers have succeeded in conferring this ability onto bacteria that do not naturally have this function. The aim is sustainable electricity generation.

New battery designed to last for a decade

A new type of flow battery has been designed. The battery stores energy in organic molecules dissolved in neutral pH water. The novel chemistry gives the battery an exceptionally long lifetime.

Hydrogen production advanced through electron spinning

Hydrogen is one of the potential renewable energy sources and part of the strategy to reduce the use of fossil fuels. One of the problems is dealing with the generation of the chemical hydrogen peroxide. A new method overcomes this.

Bacteria powered battery built on sheet of paper

New York - In the quest to find new and efficient means of generating power a research group have developed a battery, resembling a thin sheet of paper, which is powered by microorganisms.

Scientists drill into volcano to obtain energy

In an impressive technological feat, scientists and engineers have succeeded in drilling a borehole into a volcano in Iceland with the aim of using the intense heat as an energy source.

99 percent of fake Apple chargers are dangerous

A safety test of over 400 fake Apple chargers has revealed a staggering 99 percent are dangerous and pose potentially fatal risks. It comes after Apple filed a lawsuit against a counterfeit charger manufacturer selling on Amazon.

Nanotechnology boosts solar power heating

Solar power, along with tidal power and wind power, represents the leading alternative energy technology. Scientists are seeking to improve efficiency and nanotechnology offers an answer.

Why the secret of blue begonias can improve energy efficiency

Colchester - The blue sheen on the leaves of some begonias hold the key to improving energy efficiency, at the levels of the nanoscale. Researchers have discovered that chloroplasts have evolved a nanoscale light-trapping structure.

Pollutant now valued by renewable energy companies

At least one organic compound, commonly classed as a pollutant, has the potential to be used to fashion cheap, reliable batteries for use with the energy renewables sector.

Controversial new fracking to go ahead in U.K.

The path is clear for fracking to go ahead in the U.K. after the British government upheld a fracking appeal in what is being heralded as a landmark ruling, paving the way for shale gas extraction.

New steps for low cost energy generation

Physicists have taken the first steps of generating lower cost ‘green’ electricity through a combination of concentrating solar power and thermoelectric materials.

Wearable technology transforms body heat into energy

Wearable devices are increasingly common and the range of applications is growing. Many devices are limited by their need to be recharged. What is a device could draw power from the body heat of the user?

Imploding bubbles create better solar cells

Growth in solar power technology continues and considerable research efforts are orientated towards making solar panels more efficient. A novel way of doing so involves the use of imploding bubbles.

Tidal power turbines activated in Scotland

Lerwick - Tidal powered turbines installed off the coast of Shetland (Bluemull Sound) have been connected to the electricity grid and could herald a "new era" in tidal energy.

Soil bacteria used to generate electricity

In a case of physics and biology coming together, researchers have successfully created conditions under which bacteria isolated from soil generate usable electricity.

Dissolving batteries invented

Researchers have developed the world's first dissolving batteries. The main aim is to provide a positive environmental benefit, although the batteries are also energy efficient.

Vitamin-driven battery invented

Toronto - In a left-field technological development, Canadian scientists have developed the world's first vitamin-driven battery and it could transform how we power our devices in the future.
