Construction finishes on two floating mega-solar plants in Japan

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.Read More

Graphene device makes ultrafast light to energy conversion possible

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

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

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

Brio promises a safer, smarter power outlet

Most of us have a number of power outlets dotted around the house, and each one is a potential hazard to inquisitive little fingers. Brio promises a safer and smarter power outlet that can tell the difference between a kid's fingers and an electrical appliance, only turning on the juice for the latter. Read More

Envirotouch switch keeps your energy use in check

The modern home is chock-full of electrical appliances, many of which remain on standby when not in use and add unnecessary bulk to our energy bills. Thankfully, those looking to trim down on power usage aren't exactly short of options, with many devices emerging over the years designed to shut off our appliances at the wall. The Envirotouch is the latest take on the smart, energy-saving switch, relying on one-touch timer buttons to cut power to our appliances soon after we stop using them. Read More

Ammonia-based battery system to convert low-grade waste heat into electricity

As modern power generation methods are designed to squeeze the most power from the least amount of fuel, engineers are constantly looking at techniques to improve efficiency. One way to achieve this is to scavenge waste energy left over from the production process to capture and convert low-grade heat into usable energy. In pursuit of this goal, engineers at Pennsylvania State University have produced an ammonia-based battery that not only captures and converts waste heat economically and efficiently, but is claimed to do so at a greater capacity than other similar systems.Read More

Superconducting coil to slash costs and improve efficiency of direct-drive wind turbines

Conventional offshore wind turbines are expensive and complicated pieces of machinery – in a large part because of their complex and maintenance-intensive gearboxes. Dr Shahriar Hossain from the University of Wollongong in Australia is looking to slash production costs and drastically improve efficiency replacing these gearboxes with a superconducting coil.Read More
