Indian Scientists Design Solar Tree to Save Space for Solar Power Generation

Anjana Pasricha for VOA News: Indian scientists have designed a “solar tree” that they hope will help overcome one of the key challenges the country faces in the generation of solar power.

With photovoltaic panels placed at different levels on branches made of steel, “solar trees” could dramatically reduce the amount of land needed to develop solar parks.

“It takes about four-square meters of space to produce energy which otherwise would have required 400 square meters of space. So almost 100 times the space is saved, which as you know is very valuable,” said Daljit Singh Bedi, chief scientist at the Council of Scientific and Industrial Research (CSIR) in New Delhi, whose laboratory in Kolkata developed the tree.

A scarce resource in India, acquisition of land to develop roads, factories and other infrastructure is a sensitive issue that has led to frequent and sometimes violent protests from displaced people.  Cont'd...

San Bernardino County rejects a controversial solar power plant proposed for the Mojave Desert

Louis Sahagun for The LA Times:  The San Bernardino County Board of Supervisors has rejected a controversial solar plant proposed for the Mojave Desert’s Soda Mountains, citing concerns that the project would destroy habitat and block ancient trails used by bighorn sheep for thousands of years.

In a 3-2 vote, the board on Tuesday declined to certify documents required under state law in order to issue county permits for the project on public land along Interstate 15 near the entrances to Joshua Tree National Park and Death Valley National Park, and less than a mile from the Mojave National Preserve.

“We endorse renewable energy, but this was the wrong project in the wrong location,” said Supervisor Robert A. Lovingood.   Cont'd...

Could A Lithium Shortage De-Rail The Electric Car Boom?

Lithium has the purest of fundamentals of any 'commodity' out there, and the next oil barons look set to actually be lithium barons.

'Ideal' energy storage material for electric vehicles developed

Walt Mills for Phys.org:  The energy-storage goal of a polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use has been achieved by a team of Penn State materials scientists. The key is a unique three-dimensional sandwich-like structure that protects the dense electric field in the polymer/ceramic composite from dielectric breakdown. Their results are published today (Aug. 22) in the Proceedings of the National Academy of Sciences (PNAS).

"Polymers are ideal for energy storage for transportation due to their light weight, scalability and high dielectric strength," says Qing Wang, professor of materials science and engineering and the team leader. "However, the existing commercial polymer used in hybrid and electric vehicles, called BOPP, cannot stand up to the high operating temperatures without considerable additional cooling equipment. This adds to the weight and expense of the vehicles."  Cont'd...

Why Businesses Should Care About Energy & Energy Management

The added bonus of energy management is that it will make it easier to implement policies that will be more sustainable in our changing world - both environmentally and economically.

US Energy Dept says "holy grail" of clean energy storage is imminent

 

Cat Distasio for inhabitat:  Many countries are on the brink of becoming self-sufficient in their clean energy production, thanks to advances in battery technology that allow electricity from renewable sources to be stored and used on demand. Over the years, as renewable energy generation methods have charged forward, utility companies have struggled with how to integrate that clean energy in usable ways. Now, scientists at Harvard, MIT, Stanford, the Lawrence Livermore and Oak Ridge labs, and other agencies are working on energy storage projects funded by the U.S. Department of Energy, with their sights set on what the department calls the ‘holy grail’ of energy policy. The department says the industry could be transformed in as little as five to ten years.

Earlier this year, Advanced Research Projects-Energy (ARPA-E), the division of the U.S. Department of Energy founded in 2009 to oversee these projects, claimed to have achieved that goal. Without pointing to a specific invention or discovery, ARPA-E insists that the solution lies amid the 75 projects the agency is funding. The breakthrough technology—the next generation of renewable energystorage—is expected to be developed for large-scale usage in as little as five to ten years.  Cont'd...

A Danish Wind Turbine Maker Harnesses Data in a Push to Stay Ahead

Stanley Reed for The New York Times:  A project to install hundreds of wind turbines in the Fosen peninsula area of Norway at one point was shelved as unfeasible. The strong breezes that whip off the sea can shift and swing unpredictably, while the soaring cliffs and steep drop-offs create turbulence that wears out expensive equipment.

The venture was rescued with a lot of help from the mathematical calculations of Vestas Wind Systems, a Danish wind power company.  Vestas used data to figure out how to use more powerful turbines for the project, and precisely where to place them. That meant the utility developing the facility could buy fewer turbines, helping cut costs and balancing the economics of the $1.2 billion project.

The company is at the forefront of efforts to make wind a competitive source of energy, rather than just a subsidized experiment. In doing so, it has become a model for the renewables industry, which has struggled at times to remain viable while facing cuts to government subsidies and volatile oil and gas prices.  Vestas understands the fickleness of the renewable energy business.  Cont'd...

SolarCity to develop roofs made of solar cells

Lucas Mearian for ComputerWorld:  Five million roofs are replaced each year in the U.S., so instead of simply swapping out old shingles with new ones, why not turn the whole roof into a solar power generator that's integrated with your home's electrical utility?

That is SolarCity's plan for a new product it expects to begin producing next year, according to statements made during the company's second-quarter earnings calllast week.

During the call, SolarCity Chief Technology Officer Peter Rive alluded to a new product that would be produced at the soon to open Buffalo, N.Y., solar panel manufacturing facility. Then SolarCity co-founder and Chairman Elon Musk interjected and said the product would be a solar roof, "as opposed to a [solar] module on a roof."  Cont'd...

Audi converts potholes to power with new eROT system

JAKE LINGEMAN for AutoWeek:  Aim for those bumps; save the planet.  Audi is working on a new suspension system called eROT (electromechanical rotary damper) that turns the kinetic energy of damper travel into usable, fuel-saving power.

“Every pothole, every bump, every curve induces kinetic energy in the car. Today’s dampers absorb this energy, which is lost in the form of heat,” said Dr. Stefan Knirsch, board member for technical development at Audi AG. “With the new electromechanical damper system in the 48-volt electrical system, we put this energy to use. It also presents us and our customers with entirely new possibilities for adjusting the suspension.”

The electromechanical dampers are arranged horizontally and feed electricity from the motion -- 100 to 150 watts on an average road during testing in Germany -- to a lithium-ion battery. A DC converter connects the 48-volt electrical subsystem to the 12-volt primary.  Cont'd...
