WaveNET – the floating, flexible wave energy generator

By - November 26, 2014 24 Pictures
Scotland's Albatern is putting a new, modular spin on renewable energy generation. WaveNET is a scalable array of floating "Squid" generator units that harvest wave energy as their buoyant arms rise and fall with the motion of the waves. Each Squid can link up to as many as three others, effectively creating a large, floating grid that's flexible in every direction. The bigger this grid gets, the more efficient it becomes at harvesting energy, and the more different wave movements it can extract energy from. Albatern's 10-year target is to have 1.25 kilometer-long floating energy farms pumping out as much as 100 megawatts by 2024. Read More

Floating off-grid greenhouse can feed two families

By - November 19, 2014 17 Pictures
Italian design office Studiomobile has teamed up with the University of Florence's Professor Stefano Mancuso, who is the director of the International Laboratory of Plant Neurobiology, to produce a prototype floating greenhouse in a bid to improve food security in areas with little arable land. The Jellyfish Barge operates off-grid and produces its own clean water via an onboard system of solar distillation. Read More

Scotland produces enough wind energy to power all its homes

By - November 6, 2014
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

Using 'dirty silicon' to cut the cost of solar cells

By - November 5, 2014 5 Pictures
Most everyone not vested in oil and gas agrees that renewable energies such as solar are a more sustainable option, but cost remains an issue. To make solar more competitive by addressing the high cost of solar cell production, researchers out of Norway have developed a method that could bring down the amount of silicon used per unit area by as much as 90 percent. The price of silicon is a major driver in the cost of solar panels. Read More

Turning dairy farm waste into Magic Dirt

By - October 30, 2014 11 Pictures
Magic Dirt may sound like the soil used by Jack to grow his beans, but the Bioproduct Innovation of the Year award winner is just one result of a process that’s addressing the environmental issues caused by effluence from factory farm feedlots. The process starts with anaerobic digesters, specifically a patented two-stage model from Wisconsin-based DVO, which more efficiently converts manure into three valuable byproducts. Read More

Advanced offshore buoys help study wind energy potential

By - October 30, 2014 3 Pictures
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

Liquid metal alloy electrode boosts potential of sodium-beta batteries

By - August 17, 2014 3 Pictures
A new battery electrode designed at the Pacific Northwest National Laboratory (PNNL) combines liquid-state cesium and sodium to dramatically improve on the efficiency, safety and useful life of sodium-beta batteries (NBBs). If the technology is scaled up successfully, the advance could help build a smart electric grid that makes better use of renewables such as solar and wind. Read More
