Converts Over 40% of Incoming Sunlight Into Electricity

The rapid advances, coming from around the world, in alternative energy sources would have already been here and advancing further if we hadn't allowed the special interests, fossil fuel corporations and their political tools, to control the blocking of over the past forty plus years!

UNSW researchers set world record in solar energy efficiency
December 7, 2014 - Solar researchers working at the University of New South Wales (UNSW) claim to have produced a system that converts over 40 percent of incoming sunlight into electricity, thereby taking the title of highest solar efficiency for a photovoltaic system ever reported.

The researchers first achieved their record efficiency in indoor tests in a facility in Sydney, Australia, and then had these achievements duplicated and ratified by the National Renewable Energy Laboratory (NREL) using an outdoor test facility in the United States.

"This is the highest efficiency ever reported for sunlight conversion into electricity," said UNSW Professor Professor Martin Green, Director of the Australian Centre for Advanced Photovoltaics (ACAP).

The record was achieved using a combination of technologies, including heliostat mirror "power tower" concentrators from Australian company RayGen Resources and high-efficiency photovoltaic (PV) cells from Boeing subsidiary, Spectrolab, but the key component to achieving such a high-efficiency was in the use of a specifically-designed optical bandpass filter used to reject certain components of the light spectrum whilst improving the capture of others. read more>>>

Seizing Solar Power

One Latin American woman's quest to harness the power of the southern sun
08 Dec 2014 - Across Latin America the impact of poverty and climate change is bringing greater stress to rural communities.

In arid northern Argentina, people have only one source of fuel - wood. It is often scrawny bushes that are increasingly hard to find.

But the region also has a huge untapped resource – solar radiation – and Virginia Bauso's mission is to harness its potential and promote solar energy as the main power source for entire villages: from kitchens and ovens to heating, lighting, hot water and even a public phone.

She roams the desert spreading innovative technology, including a "kiosk" she invented that cooks food using the sun's rays. The community of Misa Rumi is now almost 100 percent solar-functional. Another village recently built a solar quinoa dryer, creating new opportunities for employment.

As deforestation and desertification continue to ravage Argentina and beyond, Bauso's vision could play a major role in charting a sustainable path to energy independence.

Seizing Solar Power explores how solar energy improves rural life on multiple levels by documenting its impact - in the fields of agriculture, education, health and business, as well as power - and contrasting this with isolated communities that are yet to adopt Bauso's groundbreaking tools. read more>>>

Spray-On Solar {?}

Spray-On Solar Power Coming Soon?
Dec 06, 2014 - Powering your tablet could soon be as simple as wrapping it in cling wrap, thanks to a team of scientists that recently invented a way to spray on solar power.

Lead researcher Illan Kramer and his colleagues at the University of Toronto developed miniscule light-sensitive materials called colloidal quantum dots (CQDs) that can be used to spray solar cells onto virtually any surface, from patio furniture to an airplane's wing.

The breakthrough has the potential to make manufacturing solar cells cheap and easy.

"My dream is that one day you'll have two technicians with Ghostbusters backpacks come to your house and spray your roof," Kramer explained in a statement. read more>>>

Energy Consumption Has Spurred Innovation

Alternative Energy Sources

From off-grid applications to public networks, humans are developing ways to harness renewable, cleaner sources of energy.

1 December 2014 - With a world population of more than 7 billion, energy consumption has spurred innovation for renewable sources of power. Solar, hydro and wind are among the emerging fields that allow both rural and large-scale enterprises to access energy that's renewable and has a minimum impact on the environment. Here, drivers attempt to navigate New York City on Aug. 14, 2003, during a massive blackout in the U.S. and Canada. for more visit>>>

Pushing Solar Energy Storage Solutions

US Navy Pushes Solar Energy Storage Solution
December 1st, 2014 - We just got wind of a major new oil industry campaign to tear down California’s clean energy rules, but we’re thinking these guys are going to be outflanked by the shockingly rapid growth of the energy storage sector. Case in point: the Navy Mobile Utilities Support Equipment facility in Port Hueneme, California, is hosting a new cutting edge smart microgrid project that can go into “island mode” using only solar power, thanks to vanadium flow batteries for solar energy storage.

If you’re new to the topic, it may come as somewhat of a shock to see Navy and solar energy in the same sentence. However, recall the Navy’s leadership transition from wind power to coal, oil, and nuclear energy, and you can see how this particular branch of the armed services is all over the next big energy thing like white on rice.

Advanced Energy Storage And Vanadium Flow Batteries

We’ll go over that anti-renewables campaign later this week, but for now let’s zero in on that energy storage angle. Our friends over at Imergy Power Systems are the brains behind the flow batteries, so let’s take a look at that aspect first. read more>>>

Old Blu-Ray Discs and Solar Cells Technologies

New Solar Cell Efficiency From Old Blu-Ray Discs
November 26th, 2014 - Talk about your upcycling, a research team from Northwestern University has figured out how you can boost your solar cell efficiency and get rid of your old Blu-ray discs all at the same time. We’re not about to repurpose Blade Runner because we still luvs it, but not to worry — apparently you can get the same results with just about anything on Blu-ray.

More And Better Solar Cell Efficiency

So, what’s the secret sauce? The team was inspired to tinker around with Blu-ray discs because of their superior data storage capability compared to DVDs or CDs.

The idea sounds simple enough: transfer the data storage pattern of nanoscale “islands” and “pits” from the disc to the surface of a solar cell, and you get a nano-textured surface that enhances the ability of the cell to absorb light.

The reason why that sounds simple is that texturizing is a known thing for solar cell efficiency. You can check out our friends over at Natcore for an example of “black silicon” solar cells with improved efficiency from a textured surface. read more>>>

Wearable Technologies, Portable Energy Sources

Soldiers of the future will generate own power
Wearable technologies may provide soldiers with on-the-move, portable energy and reduce the weight of gear they carry

November 19, 2014 - Wearable technologies may provide U.S. soldiers with on-the-move, portable energy and reduce the weight of gear they carry into combat.

Researchers at the Natick Soldier Research, Development and Engineering Center, or NSRDEC, here, are developing Soldier-borne energy-harvesting technologies.

During the Maneuver Fires Integration Experiment, or MFIX, a combined, multi-phase joint training exercise held in September 2014, at Fort Benning, Georgia, researchers tested prototype energy-harvesting technology solutions.

"My initial impression is that they fulfill a need for instant power generation on long-range missions when displaced from traditional resupply methods," said Sgt. 1st Class Arthur H. Jones, an infantryman with the Maneuver Center of Excellence who participated in the demonstration.

A sharp rise in Soldier-worn power capabilities has resulted in a dramatic increase in the number, variety and weight of batteries carried by warfighters in the field. read more>>>
