Counter-spinning turbine design draws double the energy from ocean waves

Scientists at Australia’s RMIT investigating the massive untapped potential of wave energy have come up with a novel design for a convertor they say operates with far greater efficiency than comparable solutions, and which they hope could open the door… Continue reading Counter-spinning turbine design draws double the energy from ocean waves

Water-filled nanogenerators harvest energy from just about any movement

There are energy sources all over the place, if you know where to look. Researchers at the Chinese University of Hong Kong (CUHK) have now designed new modular nanogenerators that can harvest energy from a variety of different types of motion, such as … Continue reading Water-filled nanogenerators harvest energy from just about any movement

Experimental “blowhole” wave energy generator goes online down under

A 200-kilowatt demonstration version of Wave Swell Energy’s fascinating “blowhole” power generator has been deployed at Grassy Harbour on King Island, off the Australian island state of Tasmania and will be connected to the grid in the coming months.Co… Continue reading Experimental “blowhole” wave energy generator goes online down under

Wave-powered AUV stations could replace crewed support ships

Although autonomous underwater vehicles (AUVs) are electrically-powered, they’re typically launched from fuel-burning surface support vessels. A new system is being designed to replace those ships with more environmentally-friendly wave-powered underwa… Continue reading Wave-powered AUV stations could replace crewed support ships

Eco Wave Power announces second grid-connected project

Back in 2012, Sweden’s Eco Wave Power started testing a wave energy harvesting system that could be installed on existing structures like breakwaters and piers. The company switched on its first grid-connected project four years later, and ha… Continue reading Eco Wave Power announces second grid-connected project
