Flower-shaped solar panel follows the sun
Megan Barber for Curbed: Based off the concept of how a sunflower follows the sun, the Smartflower is a portable, adjustable petal system that tracks the suns path throughout the day. When the sun rises in the morning, the Smartflower automatically unfolds and begins producing energy by setting its petals at a ninety-degree angle. The flower goes "back to sleep" into a folding position at night or whenever high winds make it unsafe to operate.
Low-cost 'solar absorber' promising for future power plants
Emil Venere for Phys.org: Researchers have shown how to modify commercially available silicon wafers into a structure that efficiently absorbs solar energy and withstands the high temperatures needed for "concentrated solar power" plants that might run up to 24 hours a day.
SAAB Gripen flies on 100 percent biofuel
The flights marked the first time a single-engined fighter flew with 100 percent biofuel. A twin seat Gripen D was used for the flights that took off from Saabs facilities in Linköping, Sweden.
Energy Harvesting Europe Article: A world without batteries
Energy Harvesting Europe Article: Governments, manufacturers and other interested parties agonise about what to do as multiple gigafactories spew out vast numbers of lithium-ion batteries that almost always die before the life of the equipment in which they are placed and they are linked to toxins, fires and other nasties. As the world moves to structural electronics instead of the nostalgic old components-in-a-box designs, the batteries are holding up the party because even solid state ones tend to swell and shrink with each cycle, bursting a smart structure apart.
Wind Energy Now Directly Competing With Coal On Cost
Gregory Brew for OilPrice.com: Last week, Xcel Energy announced a multi-state wind capacity project, anticipated to be the largest in the United States. Spanning seven states, the project covers eleven new wind farms and would generate 3280 MWs at a cost of $3.5-4.4 billion. In its announcement, Xcel emphasized the cost-savings attached to wind power, arguing that it would save Xcel customers in the Midwest $7.9 billion over thirty years. This, rather than the environmental benefits of renewable energy, drove the companys mission statement: wind was cheap, not just clean.
A Low-Tech Approach To Energy Storage: Molten Metals
Bruce Gellerman for WBUR: The ability to store energy promises to revolutionize the way we generate, transmit and use electricity - making renewable sources such as wind and solar cheaper and more dependable.
Massachusetts is one of just three states requiring electric utilities to build battery facilities in the future.
A company in Marlborough believes it literally has the next hot technology in energy storage: molten metals.
GTM: 10 US states have energy storage pipelines greater than 100MW
Danielle Ola for Energy Storage News: According to the latest GTM Research figures, energy storage is coming into its own and is no longer confined to a handful of US states. 21 states now have 20MW of storage projects proposed, in construction or deployed. Further, 10 states have pipelines of more than 100MW.
Fla. movin' on up with solar power
NWFDailyNews: For years, Florida has been an underachiever in solar power. Despite being ranked third in the nation for rooftop-solar potential by the Solar Energy Industries Association, Florida annually has finished in the high-teens for actual installations.
But the Sunshine State's solar prospects are beginning to brighten - and the results are making an economic impact.
Tata Power Solar Expands and Modernises its Manufacturing Facility
The two-stage expansion doubled the companys module capacity to 400 from 200 MW, and increased its cell manufacturing capacity by 65 per cent from 180 to 300 MW.
Big Oil Replaces Rigs With Wind Turbines
Jess Shankleman for Bloomberg: Big oil is starting to challenge the biggest utilities in the race to erect wind turbines at sea.
Energy storage is America's industry to lose
David Ferris, E&E News reporter: The problem, Blunden said, is that the United States is wandering into a global competition without much urgency or a plan. "Are we going to make the decision to take a significant share of the next wave of manufacturing growth globally?"
Trump Should Make Space-Based Solar Power A National Priority
Space-based solar power (SBSP) --- in which satellites in Earth orbit capture the Suns radiation, convert it to electricity and then transmit it back to Earth in the form of either microwaves or lasers --- would arguably do more to positively impact the lives of everyday Americans and fellow citizens of the world than almost anything the new President could champion.

Google: 4 out of 5 US homes have solar power potential
Steve Dent for engadget:  A five kilowatt rooftop solar installation now costs just $12,500 on average after tax credits, and pretty soon, installing one might soon be a matter of re-tiling your roof. Whether it's right for you, however, depends in large part on how much sun your house gets. That's where Google's Project Sunroof comes in -- launched just two years ago, it has now surveyed over 60 million US buildings in 50 states. That means there's a good chance you can see the electricity production potential in your city, neighborhood and even specific house.
Google calculates the amount of sunlight on your roof based on "3D modeling of your roof and nearby trees," weather patterns, the position of the sun in the sky during the year and shade from buildings, trees and other obstructions. That info is then converted to energy production "using industry standard models for solar installation performance," Google says. Â Cont'd...
Elon Musk: I can fix South Australia power network in 100 days or it's free
Elle Hunt for The Guardian: Elon Musk, the billionaire co-founder of electric car giant Tesla, has thrown down a challenge to the South Australian and federal governments, saying he can solve the state’s energy woes within 100 days – or he’ll deliver the 100MW battery storage system for free.
On Thursday, Lyndon Rive, Tesla’s vice-president for energy products, told the AFR the company could install the 100-300 megawatt hours of battery storage that would be required to prevent the power shortages that have been causing price spikes and blackouts in the state.
Thanks to stepped-up production out of Tesla’s new Gigafactory in Nevada, he said it could be achieved within 100 days. Cont'd...

Vecoplan - Planning and implementation of complete processing plants in refuse derived fuel production
In order to reduce the costs involved in the energy-intensive production of cement, many manufacturers are turning to refuse-derived fuels (RDF), considerably reducing the proportion of expensive primary fuels they would normally use. Solid fuels are being increasingly used - these might be used tyres, waste wood or mixtures of plastics, paper, composite materials and textiles. Vecoplan provides operators of cement plants with proven and robust components for conveying the material and separating iron and impurities, efficient receiving stations, storage systems and, of course, efficient shredders for an output in various qualities.
