Electricity

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
Ottobox is a smart home automation device that its makers claim could reduce your electricity bills by up to 50 percent. It does this by monitoring the appliances plugged into your wall sockets, and turning them off when they're not in use. The thinking is that all the energy wasted by appliances sitting in standby mode can soon add up to a hefty amount. Read More
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.

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.

Researchers at at Drexel University have developed a metallic nanocoating derived from a virus of the tobacco plant that could lead to more efficient steam production, improving the performance of steam turbines, air conditioning and electronics cooling systems. Read More
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.

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
In January, the VTT Technical Centre of Finland unveiled its decorative, mass-producible organic photovoltaic (OPV) leaves designed to capture energy from interior lighting to power small devices and sensors. Now, the company has followed the logical path and come up with an energy-harvesting tree that generates electricity from a variety of sources. Read More
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
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
