Vortex bladeless turbines wobble to generate energy

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

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.

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
