New wireless power tech can charge multiple devices in any orientation

By - July 10, 2015 6 Pictures

Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have developed an omnidirectional wireless charging technology that can charge multiple devices at once, at a distance and, crucially, at peak efficiency regardless of which way the devices are facing. The technology, said to be safe for humans, is set to be trialled in cafes and offices and could allow for much more convenient charging of mobile devices.

Kepler Energy reveals plans for tidal energy scheme in Bristol Channel

By - July 5, 2015 4 Pictures

With its large tidal range, Britain's Bristol Channel has a huge potential for generating tidal electric power. The problem is that, until now, schemes for tapping that power have required building dams and barrages so gigantic they would have given even the most wild-eyed Victorian engineer pause. As a more economical alternative, Kepler Energy has announced plans for a 30 MW tidal energy fence to be built in the Channel. With an estimated cost of £143 million (US$223 million), the underwater fence would be built in the water somewhere along the line between Aberthaw and Minehead and could be operational by 2021.

New nanogenerator might set energy-generating car wheels in motion

By - June 29, 2015 3 Pictures

Cars are one of mankind's most revolutionary creations. But just like with the iPhone, space travel or Wi-Fi, there's always room for improvement. In the eyes of a team of University of Wisconsin-Madison engineers, one of the more promising ways automotive technology might be improved upon lies in the energy wastage caused by friction as tires roll across the road. Armed with special nanogenerator and a toy Jeep, the researchers have demonstrated that this power can be captured and turned into electricity, a development that could bring about better fuel efficiency in the full-sized cars of the future.

Vortex bladeless turbines wobble to generate energy

By - May 19, 2015 4 Pictures
Looking somewhat like a giant reed gently swaying in the wind, the new Vortex bladeless wind-driven generator prototype produces electricity with very few moving parts, on a very small footprint, and in almost complete silence. Designed to reduce the visual and aural impact of traditional spinning-blade turbines, this new device takes advantage of the power contained in swirling vortices of air. Read More

Construction finishes on two floating mega-solar plants in Japan

By - April 23, 2015 3 Pictures
Construction has been completed on two enormous floating solar power plants located in the Nishihira Pond and Higashihira Pond in Kato City, Japan. According to The Kyocera Corporation and the Century Tokyo Leasing Corporation, who partnered up to build the instillations, the combined output of the solar plants will be around 3,300 megawatt hours (MWh) per year, and provide electricity to an estimated 920 households.

Graphene device makes ultrafast light to energy conversion possible

By - April 15, 2015 1 Picture
Converting light to electricity is one of the pillars of modern electronics, with the process essential for the operation of everything from solar cells and TV remote control receivers through to laser communications and astronomical telescopes. These devices rely on the swift and effective operation of this technology, especially in scientific equipment, to ensure the most efficient conversion rates possible. In this vein, researchers from the Institute of Photonic Sciences (Institut de Ciències Fotòniques/ICFO) in Barcelona have demonstrated a graphene-based photodetector they claim converts light into electricity in less than 50 quadrillionths of a second.

Goodyear BHO3 concept tire generates electricity

By - March 17, 2015 11 Pictures
One of the biggest hurdles that electric cars face in going mainstream is range anxiety – that dreadful realization that you're in the middle of nowhere and your car might not reach the next charging station. To help combat this, Goodyear came up with its BHO3 concept tire, which generates electricity by converting heat and motion into current as the tire rolls ... and even when it's standing still.

Tesla gearing up for release of batteries for the home

By - February 25, 2015 1 Picture
The same lithium-ion battery technology that powers Tesla’s electric vehicles will be used to develop a battery for the home, according to a statement by CEO Elon Musk during a recent conference call with analysts. The batteries would be used by homes and businesses to store excess energy generated from solar panels during the day, and drawn from at night when panels sit idle. Read More
