Make a work of art using the sun as your pen with FEBO by Caitlyn


When you think of making art, you’ll likely use a pen, pencil, or paintbrush to make your creative mark. Different tools produce different results, and if you’re avid enough in your artistic pursuits, then you likely notice and appreciate the various intricacies and approaches to each medium. Lots of modern art is very reliant on how it was made, such as the blank canvas that has 1,000 hours of a man staring at it.
While that isn’t everyone’s gig, making art powered by the sun would certainly be a neat concept. The FEBO will allow you to do this, as its job is to focus the sun and turn it into a drawing implement that will let you freehand or follow a traced piece of art. Obviously you can use any type of canvas, though you’ll want to be smart about what you choose to direct some insanely hot rays of sunlight at.
There’s no ink, graphite, or batteries that you’ll need to replenish over time, as you only need a sunny day to create new work. You will definitely need to wear sunglasses when using this, as focusing the sun to a very defined point will not do wonders for your eyeballs. Depending on the intensity of sun, you will get different strokes and thicknesses of line, making every single piece unique, even if it’s the same image. There is a colored safety filter to remove, and you’ll need to hold this at a 90 degree angle to make a mark. This will cost you anywhere from $59-97 depending on what type of wood you’d like.

Pocket-Sized Lantern Connects You to the World Even When There's No Internet Service by Beverley Mitchell




An estimated 4.3 billion people around the world don’t have internet access. In times of natural disasters, internet and phone connections also frequently fail. Lantern is a pocket-sized device designed to bring connectivity to those without internet access, using satellite-broadcast radio waves. The company behind Lantern, Outernet, aims to provide users with an anonymous, portable library that constantly receives free data from space. The device is currently acing its Indiegogo campaign, so read on for details on becoming an early adopter.





So how does Lantern work? The device continuously receives radio waves broadcast from space by Outernet’s satellite transmitters. It turns the signals into digital files, such as readable webpages, ebooks, videos, and music. The device can receive and store any type of digital file, and to view stored files users simply turn on its Wi-Fi hotspot and connect with a Wi-Fi-enabled device. Users just need a browser installed to get going. A homemade satellite receiver could perform the same function, but the Lantern packs down the equipment requirements into a flashlight-sized unit. The device even has its own solar panels to charge itself.
Outernet use the analogy of an FM radio to best describe how the system works: “Outernet is like the radio station and Lantern is the radio.” Users are not accessing the full internet, but rather a curated package of information transmitted by Outernet. Running with the metaphor, they say they are open to receiving requests from users. While this maybe enough to inspire whole forums of conspiracy theories, Outernet are at pains to point out the device’s emergency and remote educational applications.
There is plenty more information about Lantern via their Indiegogo page. A $99 pledge nabs you your own Lantern; a substantial saving off the eventual $149 estimated retail price. Now that they’ve passed their initial funding goal, Outernet are pushing on for the big one: $3 million will allow them to launch their own dedicated Cubesat, $10 million will launch a whole fleet.

History of Solar Energy

1767, First Solar Collector
In the year 1767 a Swiss scientist named Horace-Benedict de Saussure created the first solar collector – an insulated box covered with three layers of glass to absorb heat energy. Saussure’s box became widely known as the first solar oven, reaching temperatures of 230 degrees fahrenheit.
1839, Photovolataic Effect Defined
In 1839 a major milestone in the evolution of solar energy happened with the defining of the photovoltaic effect. A French scientist by the name Edmond Becquerel discovered this using two electrodes placed in an electrolyte. After exposing it to the light, electricity increased.
1873, Photo Conductivity of Selenium
In 1873, Willoughby Smith discovered photoconductivity of a material known as selenium. The discovery was to be further extended in 1876 when the same man discovered that selenium produces solar energy. Attempts were made to construct solar cells using selenium. The cell did not work out well but an important lesson was learned – that solid could convert light into electricity without heat or moving parts. The discovery laid a strong base for future developments in the history of solar power.
1883-1891 Light Discoveries and Solar Cells
During this time several inventions were made that contributed to the evolution of solar energy use. First in 1893 the first solar cell was introduced. The cell was to be wrapped with selenium wafers. Later in 1887 there was the discovery of the ultraviolet ray capacity to cause a spark jump between two electrodes. This was done by Heinrich Hertz. Later, in 1891 the first solar heater was created.
1908, Copper Collector
In 1908 William J. Baileys invented a copper collector which was constructed using copper coils and boxes. The copper collector was an improvement of the earlier done collector but the only difference was the use of copper insulation. The improvements of the invention are being used to manufacture today’s equipments.

1916, Photoelectric Effect
With Albert Einstein publishing a paper on photoelectric effect in 1905 still there was no experimental evidence about it. In 1916 a scientist known as Robert Millikan evidenced the photoelectric effect experimentally.
1947, Solar Popularity in the US
Following the Second World War, solar power equipment started being popular among many people in the USA. There was a huge demand of solar energy equipment.

1958, Solar Energy In Space
Solar power was used to power space exploration equipment such as satellites and space stations. This was the first commercial use of solar energy.
1959-1970, Efficiency of Solar Cells and Cost
During the period between 1959 and 1970 there was major discussion about the efficiency of solar cells and reduction of costs. Up to that time the efficiency of the solar cells was only 14% and was not comparable to the high cost of producing cells. However in the 1970′s, Exxon Corporation designed an efficient solar panel which was less costly to manufacture. This was a major milestone in the history of solar energy.
1977 Governments Embrace Solar Energy
In 1977 the US government embraced the use of solar energy by launching the Solar Energy Research Institute. Other governments across the world soon followed.
1981, Solar Powered Aircraft
In 1981, Paul Macready produced the first solar powered aircraft. The aircraft used more than 1600 cells, placed on its wings. The aircraft flew from France to England.
1982, Solar Powered Cars
In the year 1982 there was the development of the first solar powered cars in Australia.
1986-1999 Solar Power Plants
Evolution of large scale solar energy plants with advancement being made in each phase. By the year 1999 the largest plant was developed producing more than 20 kilowatts.
1999, Breakthroughs in Solar Cell Efficiency
The most efficient solar cell was developed, with a photovoltaic efficiency of 36 percent.
2008, Subsidy Reduction in Spain
Due to the global financial crisis in the year 2008, the Spanish government reduced subsidies on ongoing solar power production in the country. This had a negative effect on the industry across the world.
2010, Evergreen Solar and Solyndra Fail
Two leading solar companies failed. This was due to lack of market for their high technology produced products
2012, Record Breaking Solar Plants
The past few years have seen enormous investment in utility-scale solar plants, with records for the largest frequently being broken. As of 2012, the history’s largest solar energy plant is the Golmud Solar Park in China, with an installed capacity of 200 megawatts. This is arguably surpassed by India’s Gujarat Solar Park, a collection of solar farms scattered around the Gujarat region, boasting a combined installed capacity of 605 megawatts.

White Goat - Your Office will never waste paper


Your office will never waste paper again with Oriental's White Goat machine, which converts normal paper into toilet paper. Simply insert about 40 sheets of paper, and in 30 minutes you’ll receive a freshly made roll of toilet paper. The machine shreds the paper, dissolves it in water, thins it out and then dries it and winds it around a roll. According to Oriental, it costs about 12 cents to churn out one roll.
 
White Goat goes on sale in Japan this summer and will be priced at $100,000. While the machine will definitely make your business more eco-friendly, there is one snag: Where are you going to store this nearly 6-foot-tall machine?

Solar energy - the 'alternative' way forward

Noopur Tiwari, Hindustan Times  Paris, October 05, 2014

The sun could be the world’s largest source of electricity by 2050, ahead of fossil fuels, wind, hydro and nuclear, according to a pair of reports issued by the International Energy Agency (IEA).
Solar photovoltaic systems (PV) could generate up to 16% of the world’s electricity by 2050, while solar thermal electricity (STE) from concentrating solar power plants could provide an additional 11%.
A combination of both these solar technologies could prevent the emission of more than 6 billion tonnes of carbon dioxide per year by 2050 – that is more than all current energy-related CO2 emissions from the United States or almost all of the direct emissions from the transport sector worldwide today.
In most parts of India, the sun is strong and skies are clear with North-western India being one of the most favourable areas for solar power resource.
India will be able to reach the highest reduction in additional CO2 emission in 2050 and along with China could account for half the global additional emission reductions with the help of STE.
While PV is already expanding globally, with China leading the world, followed by the United States, STE is likely to expand further.  This presents a major opportunity for India, which could become the third largest producer in terms of solar power plant capacity, just behind the Middle East and the US.  This is however not a forecast on what will happen but what should happen if the right steps are taken, IEA executive director Maria van der Hoeven clarified.
“Both technologies are very capital intensive: almost all expenditures are made upfront. Lowering the cost of capital is thus of primary importance for achieving the vision in these roadmaps.”
Currently, Spain is the leading country with 2% annual electricity from solar power plants with US at second place. In the rest of the world, UAE and India have the largest plants.

Nation banks on green evolution



China's rapid transition to a green economy will be a boom both to its domestic market and the global economy, especially renewable energy industry, leading experts have said.
Commitment to developing a sustainable economy, emphasizing domestic consumption, and putting a green economy at the heart of the planning process already form the basis of China's ongoing 12th Five-Year Plan (2011-15).
"We definitely need China to succeed if the world is to succeed. Whatever China does will have global repercussions because a lot of the world's manufacturing is going on there," said Nis Hoeyrup Christensen, advisor on Chinese affairs at the Confederation of Danish Industry (CDI), and researcher in China's renewable energy sector at Copenhagen Business School.
He added that a green transition in China's manufacturing model will have especial relevance where it concerns production for the domestic market, "because that amounts to a lot of economic activity."
The UN's Environment Program defines the green economy as one where "growth in income and employment should be driven by public and private investments that reduce carbon emissions and pollution, enhance energy and resource efficiency, and prevent the loss of biodiversity and ecosystem services."
For its part, China is making a green refurbishment of its economy under a number of key headings defined in its 12th Five-Year Plan. These include that value-added output of emerging strategic industries will account for eight percent of gross domestic product (GDP), and that the country's manufacturing base in coastal regions will transit to high-end manufacturing, services and research and development.
Keystones in China's greening process include replacing coal-fired plants with those run on renewable sources like bio-mass, wind energy and solar power. Other areas involve better insulation of homes and offices to cut heating bills, combined urban heating and power networks, more recycling, improving energy-efficiency of production facilities, and developing alternative-fuel cars.
In fact, China is now the world's largest maker of wind turbines and solar panels, and its largest market for wind power. Moreover, the Chinese government says it plans to increase the share of non fossil-fuel based energy in the country's total energy consumption to 11.4 percent in 2015, up from 8.3 percent in 2010.
Green model
Denmark and its Nordic neighbors, who have been first-movers in the global green growth arena, could stand to benefit commercially from China's rapid green transition.
"I believe a more sustainable growth in China can turn out to be an advantage to Danish companies because of the technologies and solutions we have developed in our effort to create a green economy," said CEO of the CDI, Karsten Dybvad.
According to the CDI, the Danish economy has grown 78 percent since 1980, while keeping energy consumption more or less constant and slashing carbon dioxide (CO2) emissions, owing largely to technological developments in renewable energy and energy-saving.
The Danish or Nordic model of green development can be adopted in emerging economies as well, as long as they are scaled-up and adapted to fit local needs, experts say.
In fact, technology adoption and transfer would likely see Nordic technology and energy firms work even more closely with Chinese partners so as to better understand and respond to the needs of China's green market, Christensen said.
New chances
"China is at a crucial stage where the tracks will be laid out for the future direction of welfare policies and economic restructuring," Dybvad said, referring to China's move away from export-led growth and towards greater domestic consumption.
The social impact of re-balancing can perhaps be felt most palpably in the way China expects to care for its rapidly-aging population. According to Chinese official data, the country's elderly population equaled 185 million persons at the end of 2011, and is expected to be 221 million before 2015.
"Danish politicians have talked about exporting our welfare technology for a long time. This means equipment for old people's homes and hospitals, and tools which makes life easier for the elderly and for those who work with them," said Christina Boutrup, author of "China Sweet and Sour", a book on Danish companies' experiences in China.
"While this was just a dream scenario for Danish exporters in the past, China's move towards sustainability means the dream can now be realized," she added, pointing to this burgeoning area of business collaboration.
Although Danish companies can face "fierce competition from local players" when marketing welfare or energy technologies in China, Boutrup believes they hold a competitive edge as they can meet China's increasingly tighter environmental regulations, "even if they are more expensive."
Whatever the specific, future investment areas, companies will need a stable market with clear policy indicators of how best they can deploy their resources over time.
Given the Chinese government's grip on macroeconomic policy, Christensen believes these factors already exist in China and are among the stepping-stones to its green transition.
"If investors are going to put money into establishing a new technology or company, they need to be sure there is a market. In China, there is a market and a clear horizon, which the Chinese government is pretty good at showing, as it puts up both short-and-long term economic goals," he said.

SOLAR COOKING


Solar Household Energy (SHE) strives to unleash the potential of solar cooking to improve social, economic and environmental conditions in sun-rich areas around the world.
Over half the world's population currently relies on wood, charcoal or other biomass for daily cooking, leading to respiratory diseases, economic hardship, environmental degradation, and carbon emissions. Solar cooking with modern solar ovens such as the "HotPot" developed by SHE, when included as part of an integrated cooking solution, offers a practical, affordable, and sustainable alternative. Since 1998, Solar Household Energy has worked with governments, non-governmental organizations and the private sector to promote solar cooking and introduce it in developing countries through projects that distribute solar ovens and provide training for users.
We invite you to join us today in our efforts to spread the news about solar cooking and get it to those who can benefit from it most.
SOLAR COOKING NEWS:
  • Solar cooking for the Haitian/Dominican border SHE has recently partnered with The Nature Conservancy to introduce solar cooking in Tilori, Haiti near the Dominican border as part of a larger program aimed at reforesting areas denuded for charcoal production and fuelwood for cooking. SHE combined Global Sun Ovens manufactured locally in the Dominican Republic by El Fuego del Sol with fuel efficient Envirofit stoves to offer a 24/7 integrated cooking solution for this community. Training sessions and follow-up were provided to the participants to help them learn how to use their new cookstoves.
  • More HotPots for Sudanese refugees in Chad After a few months of solar cooking in the Gaga refugee camp in Chad, the Sudanese refuee recipients of HotPots distributed by Solar Household Energy at the request of U.N. High Commissioner for Refugees (UNHCR) were relieved to have an alternative to having to purchase fuelwood or risk the dangers of collecting it outside the camp. They said they wished that every woman in Gaga could have a solar oven. While not yet a reality for all 20,000 residents, SHE is now partnering withAfricare and UNHCR to distribute HotPots and providing training and follow-up for an additional 200 households in the camp.
  • Solar-fried Chicken in the Dominican Republic: Solar Household Energy has joined with a new partner, Grupo Jaragua, to distribute solar ovens in the Dominican Republic and Haiti, in order to reduce the use of wood and charcoal for cooking fires that has seriously damaged the forest cover of the island shared by these countries. DR non-profit organization, Grupo Jaragua (GJ), provides solar cooked lunches everyday at its community center in Oviedo, demonstrating how easy and tasty solar cooking can be. GJ’s chief solar chef and trainer, Olga, has even devised a method for a healthier, solar-cooked version the fried chicken dish that is the local favorite. GJ and Solar Household Energy purchase Global Sun Ovens for distribution throughout local communities from an assembly plant in the DR managed by El Fuego del Sol according to Fair Trade standards. For a limited time, a matching grant allows Solar Household Energy contributors to donate a Sun Oven to a DR or Haitian family for only $119. (A full price Sun Oven costs $279). Take advantage of this opportunity now by using the Network for Good button on this page and marking your donation for the DR.

New Dimension for Solar Energy: Innovative 3-D Designs More Than Double the Solar Power Generated Per Area




Intensive research around the world has focused on improving the performance of solar photovoltaic cells and bringing down their cost. But very little attention has been paid to the best ways of arranging those cells, which are typically placed flat on a rooftop or other surface, or sometimes attached to motorized structures that keep the cells pointed toward the sun as it crosses the sky.
Now, a team of MIT researchers has come up with a very different approach: building cubes or towers that extend the solar cells upward in three-dimensional configurations. Amazingly, the results from the structures they've tested show power output ranging from double to more than 20 times that of fixed flat panels with the same base area.
The biggest boosts in power were seen in the situations where improvements are most needed: in locations far from the equator, in winter months and on cloudier days. The new findings, based on both computer modeling and outdoor testing of real modules, have been published in the journal Energy and Environmental Science.
"I think this concept could become an important part of the future of photovoltaics," says the paper's senior author, Jeffrey Grossman, the Carl Richard Soderberg Career Development Associate Professor of Power Engineering at MIT.
The MIT team initially used a computer algorithm to explore an enormous variety of possible configurations, and developed analytic software that can test any given configuration under a whole range of latitudes, seasons and weather. Then, to confirm their model's predictions, they built and tested three different arrangements of solar cells on the roof of an MIT laboratory building for several weeks.
While the cost of a given amount of energy generated by such 3-D modules exceeds that of ordinary flat panels, the expense is partially balanced by a much higher energy output for a given footprint, as well as much more uniform power output over the course of a day, over the seasons of the year, and in the face of blockage from clouds or shadows. These improvements make power output more predictable and uniform, which could make integration with the power grid easier than with conventional systems, the authors say.
The basic physical reason for the improvement in power output -- and for the more uniform output over time -- is that the 3-D structures' vertical surfaces can collect much more sunlight during mornings, evenings and winters, when the sun is closer to the horizon, says co-author Marco Bernardi, a graduate student in MIT's Department of Materials Science and Engineering (DMSE).
The time is ripe for such an innovation, Grossman adds, because solar cells have become less expensive than accompanying support structures, wiring and installation. As the cost of the cells themselves continues to decline more quickly than these other costs, they say, the advantages of 3-D systems will grow accordingly.
"Even 10 years ago, this idea wouldn't have been economically justified because the modules cost so much," Grossman says. But now, he adds, "the cost for silicon cells is a fraction of the total cost, a trend that will continue downward in the near future." Currently, up to 65 percent of the cost of photovoltaic (PV) energy is associated with installation, permission for use of land and other components besides the cells themselves.
Although computer modeling by Grossman and his colleagues showed that the biggest advantage would come from complex shapes -- such as a cube where each face is dimpled inward -- these would be difficult to manufacture, says co-author Nicola Ferralis, a research scientist in DMSE. The algorithms can also be used to optimize and simplify shapes with little loss of energy. It turns out the difference in power output between such optimized shapes and a simpler cube is only about 10 to 15 percent -- a difference that is dwarfed by the greatly improved performance of 3-D shapes in general, he says. The team analyzed both simpler cubic and more complex accordion-like shapes in their rooftop experimental tests.
At first, the researchers were distressed when almost two weeks went by without a clear, sunny day for their tests. But then, looking at the data, they realized they had learned important lessons from the cloudy days, which showed a huge improvement in power output over conventional flat panels.
For an accordion-like tower -- the tallest structure the team tested -- the idea was to simulate a tower that "you could ship flat, and then could unfold at the site," Grossman says. Such a tower could be installed in a parking lot to provide a charging station for electric vehicles, he says.
So far, the team has modeled individual 3-D modules. A next step is to study a collection of such towers, accounting for the shadows that one tower would cast on others at different times of day. In general, 3-D shapes could have a big advantage in any location where space is limited, such as flat-rooftop installations or in urban environments, they say. Such shapes could also be used in larger-scale applications, such as solar farms, once shading effects between towers are carefully minimized.
A few other efforts -- including even a middle-school science-fair project last year -- have attempted 3-D arrangements of solar cells. But, Grossman says, "our study is different in nature, since it is the first to approach the problem with a systematic and predictive analysis."
David Gracias, an associate professor of chemical and biomolecular engineering at Johns Hopkins University who was not involved in this research, says that Grossman and his team "have demonstrated theoretical and proof-of-concept evidence that 3-D photovoltaic elements could provide significant benefits in terms of capturing light at different angles. The challenge, however, is to mass produce these elements in a cost-effective manner."

The upcoming Apple products will focus on mini integrated solar panels?




Upcoming products Apple could mount a mini- Solar Panel on the back or with an accessory Journal. The energy provided by our star would ensure a restoration in part of what is spent for the operation. The indiscretion comes from Taiwan, Again by Digitimes showing deep gorges of local manufacturing companies. That the 2012 is dedicated to the photovoltaic Cupertino?
The possibility is that Apple takes advantage of Patents deposited in 2009 for the use of solar panels for portable devices such as miniature iPad, IPhone or iPod touch: communicating with the battery, supplying a small percentage of energy.
However there is to throw some of water on the fire as Digitimes has expressed several times about the predictions that were later overturned by loud harsh reality, but this time it might take us: maybe not for a integrated directly into the device in the gadget accessories.
However, it seems unlikely that, in the case, you can see solar energy already employed with the fifth generation of Apple’s smartphone, the easier it relates to the sixth generation that should be out next year in 2012. Samsung has already presented his model of the solar Android.

Eton raises a “Rukus” at CES (by Mark R)


Eton has produced a lot of solar-powered, energy efficient gadgets over the years, and so I had to stop by at CES to see what they had for 2012. I found that they were raising quite a ruckus with their Rukus.

The Rukus is the first portable Bluetooth sound system with a solar panel to wirelessly stream music from a compatible device. As you can see, it is made to be portable, and the speakers are pretty admirable, and they produce some pretty kickin’ noise.

What really sells the Rukus is its 40 square-inch solar panel that can harvest the sun’s energy, and it takes about six hours of direct sunlight for a full recharge. The Press release says that it “never runs out of power”, but that might be too much of a boast. It is very energy efficient, and can be charged via AC adapter. By the way, the Rukus has an integrated USB port so it can charge other devices.

Although you can’t see it very well in the photo, the Rukus has an E Ink SURF segmented display, which can display information without draining the onboard battery. The display can also be read in direct sunlight and at a 180-degree viewing angle.

The Rukus will be available someone in Q2 for about $149.95.

Solar-powered Kindle cover means you never have to plug it in again (by Sean Ludwig)



If you’ve ever wanted a Kindle that you never have to plug in, SolarFocus has the accessory for you with its solar-powered Kindle case.

Green tech has dominated the conversation around cars, but now it seems these eco-friendly trends are edging into mobile at the 2012 Consumer Electronics Show, where SolarFocus is debuting its Kindle case. Taiwan-based SolarFocus has other solar-panel products that have USB ports, but its Kindle case might be the most interesting, specific device.

The solar-powered Kindle case fits only the fourth-generation Kindle, but it should be available for the Kindle Touch in the spring. The front part of the case features one long solar panel, which is a bit inelegant. On the inside, there is a pop-up light that can help you read at night or in low-lighting.

SolarFocus says its Kindle case will make the Kindle battery last three times the normal duration, which amounts to three months. But because you can charge solely off the solar charger, you could, in theory, never need to plug it into a wall or computer USB port again.

The SolarFocus solar-powered Kindle case is a 2012 International CES Innovations Design & Engineering Awards Honoree. The device will be available online starting Jan. 15 for $80.

Notre Dame researchers develop paint-on solar cells


Imagine if the next coat of paint you put on the outside of your home generates electricity from light-electricity that can be used to power the appliances and equipment on the inside. A team of researchers at the University of Notre Dame have made a major advance toward this vision by creating an inexpensive "solar paint" that uses semiconducting nanoparticles to produce energy.

 "We want to do something transformative, to move beyond current silicon-based solar technology," says Prashant Kamat, John A. Zahm Professor of Science in Chemistry and Biochemistry and an investigator in Notre Dame's Center for Nano Science and Technology (NDnano), who leads the research.

 "By incorporating power-producing nanoparticles, called quantum dots, into a spreadable compound, we've made a one-coat solar paint that can be applied to any conductive surface without special equipment."

 The team's search for the new material, described in the journal ACS Nano, centered on nano-sized particles of titanium dioxide, which were coated with either cadmium sulfide or cadmium selenide. The particles were then suspended in a water-alcohol mixture to create a paste.

 When the paste was brushed onto a transparent conducting material and exposed to light, it created electricity.

 "The best light-to-energy conversion efficiency we've reached so far is 1 percent, which is well behind the usual 10 to 15 percent efficiency of commercial silicon solar cells," explains Kamat.

 "But this paint can be made cheaply and in large quantities. If we can improve the efficiency somewhat, we may be able to make a real difference in meeting energy needs in the future."

 "That's why we've christened the new paint, Sun-Believable," he adds.

 Kamat and his team also plan to study ways to improve the stability of the new material.

 NDnano is one of the leading nanotechnology centers in the world. Its mission is to study and manipulate the properties of materials and devices, as well as their interfaces with living systems, at the nano-scale.

South Africa’s Solar Power Potential


As the United Nations climate change conference rages on, quite literally, in Durban, South Africa, experts from COP17’s host city point to one alternative energy source that could help it mitigate its emissions: solar power.
According to Dick Berlijn, of Subsolar Energy, Durban has one of the highest and most stable solar radiation levels in the world. “The variable is around 3%. That means that on a good day, solar radiation in South Africa is 100% and 97% on bad days. These conditions are extraordinary,” MD for Pretoria-based Subsolar Energy toldIndustry Leaders magazine.
With so much solar radiation, Berlijn believes solar is better qualified to produce clean energy for South Africa than wind. Besides, South Africa also has plenty of space to build solar photovoltaic (PV) plants.
South Africa needs to start moving towards alternative energy as the country still relies heavily on coal for electric power (90%). The country is the 16th biggest emitter in the global ranking, having dumped 369,4 million tons of CO2 in the atmosphere in 2009.
SolarPlaza’s Solar Future South Africa convention which will take place in Johannesburg in January 2012 will be discussing the country’s solar potential and related topics such as job creation, Feed-in Tariffs and business opportunities.

A Light Wave of Innovation to Advance Solar Energy: Researchers Adapt Classic Antennas to Harness More Power from the Sun


Some solar devices, like calculators, only need a small panel of solar cells to function. But supplying enough power to meet all our daily needs would require enormous solar panels. And solar-powered energy collected by panels made of silicon, a semiconductor material, is limited -- contemporary panel technology can only convert approximately seven percent of optical solar waves into electric current.

Profs. Koby Scheuer, Yael Hanin and Amir Boag of Tel Aviv University's Department of Physical Electronics and its innovative new Renewable Energy Center are now developing a solar panel composed of nano-antennas instead of semiconductors. By adapting classic metallic antennas to absorb light waves at optical frequencies, a much higher conversion rate from light into useable energy could be achieved. Such efficiency, combined with a lower material cost, would mean a cost-effective way to harvest and utilize "green" energy.
The technology was recently presented at Photonics West in San Francisco and published in the conference proceedings.

Receiving and transmitting green energy

Both radio and optical waves are electromagnetic energy, Prof. Scheuer explains. When these waves are harvested, electrons are generated that can be converted into electric current. Traditionally, detectors based on semiconducting materials like silicon are used to interface with light, while radio waves are captured by antenna.
For optimal absorption, the antenna dimensions must correspond to the light's very short wavelength -- a challenge in optical frequencies that plagued engineers in the past, but now we are able to fabricate antennas less than a micron in length. To test the efficacy of their antennas, Prof. Scheuer and his colleagues measured their ability to absorb and remit energy. "In order to function, an antenna must form a circuit, receiving and transmitting," says Prof. Scheuer, who points to the example of a cell phone, whose small, hidden antenna both receives and transmits radio waves in order to complete a call or send a message.
By illuminating the antennas, the researchers were able to measure the antennas' ability to re-emit radiation efficiently, and determine how much power is lost in the circuit -- a simple matter of measuring the wattage going in and coming back out. Initial tests indicate that 95 percent of the wattage going into the antenna comes out, meaning that only five percent is wasted.
According to Prof. Scheuer, these "old school" antennas also have greater potential for solar energy because they can collect wavelengths across a much broader spectrum of light. The solar spectrum is very broad, he explains, with UV or infrared rays ranging from ten microns to less than two hundred nanometers. No semiconductor can handle this broad a spectrum, and they absorb only a fraction of the available energy. A group of antennas, however, can be manufactured in different lengths with the same materials and process, exploiting the entire available spectrum of light.
When finished, the team's new solar panels will be large sheets of plastic which, with the use of a nano-imprinting lithography machine, will be imprinted with varying lengths and shapes of metallic antennas.

Improving solar power's bottom line

The researchers have already constructed a model of a possible solar panel. The next step, says Prof. Scheuer, is to focus on the conversion process -- how electromagnetic energy becomes electric current, and how the process can be improved.
The goal is not only to improve the efficiency of solar panels, but also to make the technology a viable option in terms of cost. Silicon is a relatively inexpensive semiconductor, but in order to obtain sufficient power from antennas, you need a very large panel -- which becomes expensive. Green energy sources need to be evaluated not only by what they can contribute environmentally, but also the return on every dollar invested, Prof. Scheuer notes. "Our antenna is based on metal -- aluminium and gold -- in very small quantities. It has the potential to be more efficient and less expensive."
