New navigation module to help future freighters act as their own sails

In 2013, Norway's Lade AS unveiled designs for Vindskip, a "hybrid" merchant ship which aims to harness the wind courtesy of a specially-shaped hull, in the process taking the burden off of its natural-gas powered engines and saving fuel. Researchers from the Fraunhofer Institute's Center for Maritime Logistics and Services (CML) have been working to help realize this goal by developing an algorithm that will allow the Vindskip's navigation system to use the combination of power and sail at its most economical.

Scotland produces enough wind energy to power all its homes

Scotland is pushing ahead with green energy, with First Minister Alex Salmond claiming that renewables could provide 100 percent of Scotland's energy by 2025. And last month, Salmond's push for wind farms appears to have borne fruit – wind power alone generated some 126 percent of the energy needed to power every home in Scotland in what the World Wildlife Foundation (WWF) is calling a "bumper month." Even solar fared well despite the chilly conditions, with domestic solar PV panels chipping in around a third of the domestic energy bill. Read More

Advanced offshore buoys help study wind energy potential

Offshore wind power in the United States is nowhere close to meeting the potential this renewable energy form has to offer. There are a myriad of reasons why, including lack of information on energy-harnessing possibilities at specific sites. The US Department of Energy’s Pacific Northwest National Laboratory (PNNL) is looking to change this, by dropping two very advanced data-collecting buoys into coastal waters. Read More

GE uses plastic surgery on wind turbine blades for more power

Sometimes progress can be its own worst enemy, with early adopters being stuck with obsolete equipment that leaves them with the choice of living with out-dated technology or an expensive replacement. The green energy field isn’t immune to this, and as part of a US$2 million renewable energy project, GE has developed a way to make smaller, less efficient wind turbines into bigger more efficient ones with a bit of plastic (or carbon composite) surgery.

WindPax portable, collapsible wind turbines take a turn at off grid power

Keeping mobile electronic devices powered up can be difficult for the modern camper and hiker. Generating power from Mother Nature in the form of wind and sun is the preferred option for many, with a number of portable solar and wind generators emerging to fill this need. The latest is Windpax, a collapsible, portable wind turbine system designed to not take up too much space in a backpack. Read More
