The innovators: how tiny amounts of wind energy could light up Africa

The plastic sheets have slivers of bendable filaments that stand up and are moved by gusts of air. The filaments, which are encased in plastic, work using the piezoelectric effect – the ability of some materials to generate a charge in response to pressure. In this case, when the filaments are moved by gusts of […]

Scientists build toy car propelled by evaporating water

Researchers at Columbia University in New York have built a miniature car that draws on the process to propel itself along, as well as an evaporation-driven generator that powers a flashing LED lamp. The inventions pave the way for a new generation of renewable devices that extract energy from natural evaporation and transform it into […]

These bladeless wind turbines shake to generate electricity

Farms dotted with the gigantic spinning blades of wind turbines have become a standard sight on long-distance road trips, but what if there was another way to capture energy from the wind? A startup out of Spain is working on that very idea. The company’s called Vortex Bladeless, and its turbines look like stalks of […]

Solar sails set course for a new journey into renewable energy

“Solar is moving from being a hard, inflexible and one-colour product to being soft lightweight, flexible, and maybe even multicoloured,” he said. “In solar everybody only knows those glass panels going on roofs and on farmland, fields, solar farms. Why can’t solar be everywhere in all different types of aspects? Read the full story here

University installs prototype ‘pee power’ toilet

A prototype toilet has been launched on a UK university campus to prove that urine can generate electricity, and show its potential for helping to light cubicles in international refugee camps. Students and staff at the Bristol-based University of the West of England are being asked to use the working urinal to feed microbial fuel […]
