Wave-powered Desalination

Written by , on October 28, 2016

The current test device is able to produce about 1,900 litres of fresh waste a day. A slightly larger production unit is planned to produce up to 13,000 lites of desalinated water per day at about half of current desalination processes.  Read more »

10 Years of Progress in Renewables

Written by , on June 19, 2015

In its 2015 “Global Status Report”, REN21, the global renewable energy policy network, has summarised the increase in renewable energy capacity in the 10 years from 2004 to 2014. In 2004, global renewable power capacity (excluding hydro) was 85 gigawatts. In 2014, it reached 657 gigawatts.  Read more »

Power from a “Wave Carpet”

Written by , on February 7, 2014

University of California Berkeley professor Reza Alam and his team have developed a "wave carpet" which can extract the energy of ocean waves and turn it into electricity or fresh water The "wave carpet" is a rubber mat which sit on top of a grid of hydraulic actuators, cylinders and pumps, on a muddy ocean […]  Read more »

Italy to Get Wave Power Plant

Written by , on May 24, 2013

UK based 40South Limited is to install a 150 kilowatt wave power module outside Livorno Port in Tuscany. The device uses two connected buoyant sections that sit one above the other at different depths. The lower section is moored to the seabed. The arms that connect them move inside each other like pistons, generating power […]  Read more »

Maths Could Double Power from Waves

Written by , on July 4, 2012

A team of mathematicians and engineers from the University of Exeter and Tel Aviv University have devised a means of accurately predicting the power of the next incoming wave in order to make wave power technology far more efficient – potentially extracting twice as much energy as is currently possible. The key challenges for wave […]  Read more »

Study: Current Technolgy Could Power the World

Written by , on January 28, 2011

According to a new study by Stanford researcher Mark Jacobson and Mark Delucchi, of the University of California-Davis, by 2030 all new energy generation could come from wind, water and solar, and by 2050, all pre-existing energy production could be converted to renewables, using only technology that is already available and at a similar cost […]  Read more »

Wave Energy from Undersea Wings

Written by , on December 15, 2010

The Florida Institute of Technology is testing a new technology to convert the energy produced by waves into electricity, The so-called Wing Waves work by tapping the elliptical motion of waves 20 to 30 metres beneath the surface and converting it into mechanical energy that can be used to generate power. Each trapezoid-shaped wing of […]  Read more »
