World’s First Solar-Powered Nation

Tokelau To Be World's First Solar-Powered Nation -


The small nation of Tokelau in the South Pacific will be entirely powered by solar energy by the end of 2012, reports 3News in New Zealand, making it the first nation in the world to do so.

More than 4,000 solar panels are being installed on the three atolls that make up the nation – Fakaofo, Nukunonu and Atafu – and will supply all the energy needed by its 1,400 residents. The first atoll to go completely solar, Fakaofo, is scheduled to have its diesel generators turned off next week. “It’s been quite a milestone week for us, we now have all the solar panels erected, 1584 solar modules, all the batteries are in place,” said mechanical engineer Dean Parchomchuk from Powersmart Solar, which is responsible for the panel installations.

Introduction to Tokelau:

Tokelau is a non-self-governing territory of New Zealand consisting of three coral atolls in the South Pacific: Atafu, Nukunonu, and Fakaofo. These atolls lie approximately mid-way between Hawaii and New Zealand and about 500 km north of Samoa.

Formerly known as the Union Islands, the name 'Tokelau Islands' was adopted in 1946 and then shortened to 'Tokelau' in 1976.

The roughly 1500 hardy inhabitants of Tokelau, unofficially known as Tokelauans, are thought to have settled the islands more than a thousand years ago- thus, they are generically recognized as being Polynesians (and darn proud of it) - and this pride fits well with their culture...
Simply put, Tokelau culture IS Polynesian culture.

Lead contractor Powersmart Solar is helping Tokelau replace its diesel generators - which burn about 200 litres of fuel daily - with 4032 solar panels, 392 inverters and 1344 batteries.

Powersmart Solar director Mike Bassett-Smith said the company was proud to be leading the project because of the impact it would have on the well-being of the people of Tokelau.

[...]

The solar power systems will be capable of providing 150 per cent of the annual electricity demand without increasing diesel demand.

Companies from all over the globe tendered for the project and it was a "big win" for the Mount Maunganui-based company, Bassett-Smith said.

Alien Photosynthesis

Far-Out Photosynthesis

Photosynthesis maintains Earth's habitability for life as we know it, and shapes the way we search for habitable worlds around distant stars. Scientists have discovered a microbe that can use low-energy light to perform photosynthesis. This discovery could alter theories about the types of stars that could support Earth-like worlds.

In the process of photosynthesis on Earth, plants convert energy from the sun into chemical energy in the form of glucose, or sugar. The chlorophyll in plants absorbs more blue and red light from sunlight, and less green light. Chlorophyll is green, because it reflects green light more than blue and red light. Credit: NASA Ames


Different types of stars have different temperatures and lifetimes. Cooler red M-class stars live a long time, while hotter blue A-class stars have relatively brief lives. These four pictures are actually four different views of our own star, the sun. Each false-color view highlights atomic emission in different temperature regimes of the upper solar atmosphere. Yellow is 2 million Kelvin, green is 1.5 million K, blue is 1 million K, and red is 60 to 80 thousand K. Image Credit: Stereo Project/NASA

NASA GISS: Research Features: Far-Out Photosynthesis

Kiang emphasizes the implications that the findings could have in the search for life on extrasolar planets - and the future of life here on Earth:

1) "Planets orbiting red dwarf stars may not get much visible light, but they'll get a lot of NIR light. So, now we know it would still make sense to look for oxygenic photosynthesis on such planets, and we could look for pigment signatures in the NIR."

2) "A. marina appears to be a late evolution, occupying a light niche that is produced by leftover photons from Chl a organisms. Since it can use more solar radiation than Chl a organisms, might our planet evolve to have Chl d outcompete Chl a?"

3) "Biomimicry of photosynthesis continues to be a quest in the development of renewable energy, but no one has yet developed an artificial system as good as Nature to split water. For renewable energy that depends on sunlight, do the lower energy photons used with Chl d mean that we don't need such strong artificial catalysts for producing hydrogen fuel and biofuels?"

The findings could completely change our understanding of a biological reaction that is essential to the modern biosphere of Earth. They may also open new doors for the future of humankind in areas like renewable energy. But for NASA, the study could also have implications for the future of life on Earth — and beyond — that are truly far out.

OLPC's XO 3 a $100 Solar-Powered Tablet

The Next List: Yves Behar wants design to change the world - Feb. 24, 2012

A $100 solar-powered tablet is coming soon

NEW YORK (CNNMoney) -- You may not have heard of Yves Behar, but chances are you've seen his designs.

He's the visionary behind the popular Jawbone Jambox sound system, Herman Miller's Sayl chairs, Swarovski chandeliers, and even New York City's free condoms.

The Swiss designer, now based in San Francisco, has plenty of commercial hits. That gives him the financial freedom to pursue his belief that design can change the world. It's a passion he put to work on his most famous project, One Laptop Per Child, better known as "the $100 laptop."

Now he's nearing completion of the sequel: A $100 tablet. It's rugged, solar-powered, and designed for children in the world's poorest countries.




Gizmo - OLPC XO 3.0 Tablet - YouTube

The first tablet from One Laptop Per Child gets unveiled! It is a pretty nice device and should cost $100. It features a very low power consuming Marvell ARM processor, up to 1GHz speed, 500MB of RAM, USB ports, 4GB of storage. It can also run Android, Sugar OS, even Linux.



OLPC's XO 3 tablet uses 1GHz ARM SoC to run Sugar Linux or Android - News - Linux for Devices


One Laptop per Child (OLPC) demonstrated a "fully functional" version of its long-delayed XO 3.0 tablet, equipped with a 1GHz Marvell Armada PXA618 processor running Sugar Linux or Android 3.x. Like OLPC's XO 2 laptop, the eight-inch tablet is aimed at educational systems in developing nations, and it will feature an optional sunlight-readable Pixel Qi touchscreen plus the ability to draw power from an optional solar panel or crank charger.
[...]
The XO 3.0 tablet will feature the 1GHz Marvell Armada PXA618 SoC, a member of Marvell's PXA610 line of ARMv7 processors, and will also include an Avastar Wi-Fi SoC, say Marvell and OLPC. The XO 3 ships with a standard LCD touchscreen or an optional Pixel Qi low-power, sunlight-readable display, say the partners. Other features are said to include a "unique" charging circuitry that can be charged directly by solar panels, hand cranks, and other alternative power sources. Alternative power has been a longtime goal of OLPC that wasn't implemented in earlier XO designs.

Singapore Punggol Eco Town -- Panasonic's Test-bed on Total Energy Solutions for Public Housing

Panasonic to Develop EcoTown Project in Singapore


Singapore’s Housing and Development Board, Energy Market Authority and Economic Development Board have partnered with Panasonic to develop an Eco Town. Ten apartments in a housing complex in Singapore have been selected to be models of the viability of energy efficiency in open housing; the project will be officially called the Punggol Eco Town.
[...]
The project will run from 2011 to 2013. Punggol Eco Town will gradually move to run entirely clean energy and reduce energy use by 75 percent. The Ecotown will have photovoltaic system to run their elevators; this means that their elevators will run by solar radiation that is converted to electricity. Solar panels will be installed throughout the units. The idea is that a resident will be able to open their garage door or switch on their TV without any environmental impact.





Panasonic Announces Asia's First Test-bed Project on Total Energy Solutions for Public Housing | Panasonic News Portal



Panasonic's photovoltaic systems will be installed to supply renewable energy to power common facilities; aiming to challenge zero emissions target and its Home Energy Management System (HEMS) will help households monitor and better manage energy consumption via an in-home display (IHD) which are provided as part of the test-bed project. Demand response will be achieved through Panasonic's Smart Energy Gateway (SEG) which connects the smart meter and home appliances such as air conditioners. As part of the bigger picture, the HEMS will be connected to the government-owned smart meters and smart grid technology; to enhance the efficiency and resilience of Singapore's power system.

LUNA RING: Solar Power via the Moon


Shimizu Corporation construction firm’s research branch, CSP, unveiled a long-term planning project to install a belt of photovoltaic panels across the surface of the Moon. Power gathered from the 13,000 terrawatts of continuous solar energy the Moon’s surface receives daily would be beamed back to an Earth-based receiving station via microwave or laser transmission, where it would then be used to power public offices, hospitals and schools across the globe. A staff of remotely controlled robots would be in constant rotation to make repairs and provide maintenance for the LUNA RING installation, though the structure would require some human personnel on-site. To make the process more efficient, the proposed plan includes building the LUNA RING’s solar panels on the lunar surface using local materials, rather than launching pre-built panels to the site.

Fuel From Sunlight

New solar fuel machine 'mimics plant life'

A prototype solar device has been unveiled which mimics plant life, turning the Sun's energy into fuel. 

The machine uses the Sun's rays and a metal oxide called ceria to break down carbon dioxide or water into fuels which can be stored and transported.

Conventional photovoltaic panels must use the electricity they generate in situ, and cannot deliver power at night.

Details are published in the journal Science.



As described in an article in Clean Energy Authority.com, the device consists of a quartz lens that focuses the solar radiation on a reaction chamber that is internally reflective and captures most of the photons that enter and converts them to heat. The device heats up at a rate of 140 degrees Celsius a minute until it reaches about 1,250 degrees Celsius, and stabilizing at more than 1,400 degrees Celsius. Through a two-step process, the device’s catalyst ceria (cerium dioxide) converts CO2 or water into its constituent elements.


Haile said in an interview, “Ceria is a metal oxide, what that material will do when heated is it will release oxygen.…It happens at high temperatures, when we cool it back down it wants to absorb oxygen.  “The ceria replaces the oxygen by stripping it from the supplied material, carbon dioxide or water, thereby creating carbon monoxide—used for syngas, or hydrogen—which can be used directly. Either resulting fuel could be used to store the sun’s energy for use in power generation.”





Doped CeO2 with a low specific surface area is thermochemically cycled between MO2 and MO2−δ using H2O and CO2 as oxidants. The system rapidly and selectively produces syngas in the absence of a metal catalyst, and CH4 in the presence of Ni. [...]


Ethiopian Scientist develops reactor to make fuel from sunlight





“We have a big energy problem and we have to think big,” said Prof Sossina Haile, at the California Institute of Technology, who led the research.

Haile estimates that a rooftop reactor could produce about three gallons of fuel a day. She thinks transport fuels would be the first application of the reactor, if it goes on to commercial use. But she said an equally important use for the renewable fuels would be to store solar energy so it is available at times of peak demand, and overnight. She says the first improvements that will be made to the existing reactor will be to improve the insulation to help stop heat loss, a simple move that she expects to treble the current efficiency.

The key component is made from the metal cerium, which is almost as abundant as copper, unlike other rare and expensive metals frequently used as catalysts, such as platinum. Therefore, said Haile, availability would not limit the use of the device. “There is nothing cost prohibitive in our set-up,” she said. “And there is plenty of cerium for this technology to make a major contribution to global gasoline supplies.”

Solar Energy Powered Oriental Hornets

BBC - Earth News - Oriental hornets powered by 'solar energy'



The Oriental hornet has a unique ability to harvest solar energy, scientists have discovered.

The large wasp species has a special structure in its abdomen that traps the sun's rays, and a special pigment that harvests the energy they contain.

The discovery helps explain why these hornets have a large yellow stripe across their body and why they become more active as the day gets hotter.

It also changes our understanding of how insect metabolism can work.


Marian Plotkin of Tel Aviv University and colleagues used advanced microscopes to examine a hornet's exoskeleton, or cuticle. Most of the cuticle is brown, but a few sections are yellow. These colours mark the hornet as a venomous insect, and therefore best avoided by potential predators, but the pigments are also involved in mopping up solar energy.

Both the brown and yellow cuticles are made up of many layers laid on top of each other, around 30 in the brown and 15 in the yellow. The brown areas contain melanin, a pigment also found in human skin, while the yellow areas contain xanthopterin.

Plotkin found that the brown cuticle is covered with grooves, while the yellow cuticle is covered with oval-shaped lumps. Both absorbed 99 per cent of the visible light falling on them.

What's more, the grooves on the brown cuticle are fairly regularly spaced, Plotkin found. As a result, the cuticle surface mimics a series of slits, which act as a diffraction grating, trapping yet more light inside the cuticle layers.

The team also built a solar cell that successfully used xanthopterin to harvest light.

Helios Solar Energy Research Center (SERC) -- “Artificial Photosynthesis”

Black Is the New Green | Alternative Energy | DISCOVER Magazine


Scientists are learning to mimic nature to produce clean energy, by re-creating photosynthesis in the lab.

Lilac Amirav is breaking a sweat trying to do what nature has been doing effortlessly for some 3 billion years.
[...]
 Amirav’s goal is to tweak this process to better suit the energy needs of a world population that by 2050 is expected to reach 9 billion, a growing percentage of which will want to drive their own cars. She and her colleagues at Helios, a joint project of U.C. Berkeley and Lawrence Berkeley National Laboratory, want to build an artificial leaf that drips ethanol, or some other alcohol, which you could pump right into your gas tank.

Berkeley Lab


The Solar Energy Research Center (SERC) is one of three Helios projects in which researchers from Lawrence Berkeley National Laboratory (LBNL) are working to develop fuels from sunlight.

The goal of Helios SERC is to produce carbon-neutral transportation fuels using solar energy as the source of stored energy

New Nano-sized Photocatalyst for Artificial Photosynthesis; Step Toward Production of Carbon-Neutral Transportation Fuels


Artificial photosynthesis for the production of liquid fuels is a potential source for renewable and carbon-neutral of transportation energy. The basic concept is to integrate light-harvesting systems that can capture solar photons and catalytic systems that can oxidize water, then to combine this water oxidation half reaction with a carbon dioxide reduction step in an artificial-leaf type system to produce a liquid hydrocarbon, such as methanol (CH3OH), that can be stored, transported, and used for transportation or other applications.

Researchers with the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have now found that nano-sized crystals of cobalt oxide can effectively carry out the critical photosynthetic reaction of splitting water molecules. Heinz Frei, a chemist with Berkeley Lab’s Physical Biosciences Division, and his postdoctoral fellow Feng Jiao reported the results of their study in the journal Angewandte Chemie, in a paper entitled: “Nanostructured Cobalt Oxide Clusters in Mesoporous Silica as Efficient Oxygen-Evolving Catalysts.”

An aqueous solution contains silica particles that have been embedded with photooxidizing cobalt oxide nanocrystals plus a sensitizer to allow the water-splitting reaction to be driven by visible light. When laser light hits the solution it turns blue as the sensitizer absorbs light.

Highly Efficient Solar Cells using Hot Electron Transfer

University of Minnesota researchers clear major hurdle in road to high-efficiency solar cells


MINNEAPOLIS / ST. PAUL (06/17/2010) —A team of University of Minnesota-led researchers has cleared a major hurdle in the drive to build solar cells with potential efficiencies up to twice as high as current levels, which rarely exceed 30 percent.

By showing how energy that is now being lost from semiconductors in solar cells can be captured and transferred to electric circuits, the team has opened a new avenue for solar cell researchers seeking to build cheaper, more efficient solar energy devices. The work is published in this week’s Science.

A system built on the research could also slash the cost of manufacturing solar cells by removing the need to process them at very high temperatures.



Quantum Dots Could Minimize Energy Loss in Solar Cells


Researchers from the University of Texas in Austin and the University of Minnesota in Minneapolis have discovered that hot electrons can be transferred from quantum dots to an electron acceptor. This process could, theoretically, be used to increase the conversion efficiency of solar cells to 66%.

In typical semiconductor solar cells, photons with energies above the semiconductor’s bandgap generate hot electrons, and much of the energy from the hot electrons is lost through heat before it can be captured and used for electricity.

Using these hot electrons requires slowing down how fast they cool, which quantum dots can do. Then the electrons must be captured and transferred. As detailed in Science, the researchers were able to observe transfer of hot electrons from colloidal lead selenide (PbSe) quantum dots to a titanium dioxide (TiO2) electron acceptor using time-resolved optical second harmonic generation.



The University of Texas at Austin- What Starts Here Changes the World

Highly Efficient Solar Cells Could Result from Quantum Dot Research

Dr. Xiaoyang Zhu, professor of chemistry, has discovered a method to capture the higher energy sunlight that is lost as heat in conventional solar cells.

"There are a few steps needed to create what I call this 'ultimate solar cell,'" says Zhu, professor of chemistry and director of the Center for Materials Chemistry. "First, the cooling rate of hot electrons needs to be slowed down. Second, we need to be able to grab those hot electrons and use them quickly before they lose all of their energy."
[...]

Zhu's team has now figured out the next critical step: how to take those electrons out.
They discovered that hot electrons can be transferred from photo-excited lead selenide nanocrystals to an electron conductor made of widely used titanium dioxide.

"If we take the hot electrons out, we can do work with them," says Zhu. "The demonstration of this hot electron transfer establishes that a highly efficient hot carrier solar cell is not just a theoretical concept, but an experimental possibility."

Solar Power From Sahara

Europe Will Be Powered By Saharan Sun in Five Years



The super-sized solar projects being built in the Sahara desert will start generating and providing Europe with clean energy within the next five years, according to the European energy commissioner.  This is much sooner, than the initial 10-year time frame given to the project.



Reuters Africa

EU sees solar power imported from Sahara in 5 yrs

ALGIERS (Reuters) - Europe will import its first solar-generated electricity from North Africa within the next five years, European Energy Commissioner Guenther Oettinger said in an interview on Sunday.

The European Union is backing projects to turn the plentiful sunlight in the Sahara desert into electricity for power-hungry Europe, a scheme it hopes will help meet its target of deriving 20 percent of its energy from renewable sources in 2020.

"I think some models starting in the next 5 years will bring some hundreds of megawatts to the European market," Oettinger told Reuters after a meeting with energy ministers from Algeria, Morocco and Tunisia.







The Concept at a glance


"In the coming decades, global developments will confront mankind with unprecedented challenges: climate change, a population growth far beyond Earth‘s present carrying capacity, the global striving for prosperity, and increasing demands for energy and water, are the core problems we are faced with. 200 years of global industrialization has resulted in an unparalleled standard of living and an increased life expectancy for part of the world’s population. However, all this has been and is still being achieved at a price: alarming environmental destruction as well as climate change which can no longer be ignored. These things will mean dramatic changes to life on Earth in the future."

Desertec solar energy project




Generating Electricity in the Sahara Desert


There are two main types of solar generation planned for North Africa. The first is standard photovoltaic solar panels (PV). Thanks to the number of sunshine hours, the clean dry air, and the latitude of the Sahara Desert, a solar panel installed there will generate up to 3x as much power than it would if it was installed in the UK.
The second (and more likely) is to use concentrated solar power (CSP) - an array of mirrors which focus the sun's rays onto a single point to make super-heated steam to turn a turbine (pictured above). See our article First European Solar Power Tower for information on how this technology is already being used in Southern Spain.

European Supergrid - HVDC Transmission

 
If renewable energy is to be used to power Europe, then a new low-loss electricity grid will need to be constructed. The UK national grid for example transmits high voltage ACwind energy from UK is to be used in Bulgaria, or if Saharan solar electricity is to be used in UK, more efficient transmission would be essential.
The plan is to create a Europe-wide supergrid of low loss high voltage DC (direct current) cables. HVDC cables have energy losses as low as 3% per 1000km, and their use will make it easier for countries which generate AC electricity at different frequencies to synchronise and pool green electricity. Current estimates put the cost of such a supergrid at around 45 Billion Euro.
