    We all know that the sun is the greatest sustainable energy source on earth. Since more than over 40 years the Technology helps us to transform this source into power. The problem is the low efficiency: 80% of installed PV panels worldwide have a performance of 15% or lower; but if the panels are not tracked with the sun, the average of annual tilt losses add up to minus 70%.

    “We can squeeze more juice out of the sun.”

    The Concept

    We've been through a long research and creative process, from early studies, concepts and sketches to 3D models, calculations and prototypes, loads of Ball lens studies, through to measuring the performance and the energy transmission values. Through these tests we reached the conclusion that the perfect shape of the ball lens not only has excellent energy transmission, but also the capability to concentrate diffuse light.

    The KymoGen Wave Energy Generator is a source of clean, renewable power that will change the world of green energy.

    The KymoGen is a platform that will float offshore, tethered to a mooring. When a wave approaches, the platform will rise, pulling on the mooring tether. As the wave passes, the platform resets to its original position for the next wave. The mooring tether is attached to a drive system inside of the KymoGen. When the mooring tether is pulled, it spins a flywheel, which will provide constant power between waves. The energy is then transferred to a generator.

    Viaducts with wind turbines, the new renewable energy source


    Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity. So it is confirmed by calculations carried out by a European researchers team, that have taken a viaduct in the Canary Islands as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations.

    The Juncal Viaduct, in Gran Canaria, has served as a reference for Spanish and British researchers to verify that the wind blowing between the pillars on this kind of infrastructures can move wind turbines and produce energy.

    The study is based in models and computer simulations, which were carried out by researcher Oscar Soto and his colleagues in Kingston University (London). Researchers have presented the wind turbines as porous discs in order to evaluate the air resistance and test different kind of configurations.

    "As natural, the more surface is swiped by the rotor, the more power can be produced; however, it was seen that in small turbines the power rate per square meter is higher", explains Soto, who considers that the configurations with two identical turbines would be the most viable to be installed in viaducts.

    If only produced power was evaluated, the best solutions would be the installation of two wind turbines with different sizes - in order to embrace the maximum available space-, or even a matrix of 24 small turbines - due to their power production per surface unit and low weight-, but concerning to viability, the best option is the one which includes two medium sized wind turbines.

    Results confirm that each viaduct presents specific energy possibilities and wind potential. In the Juncal Viaduct case, the evaluated power would be about 0,25 MW per wind turbine. So, with two turbines, the total power output would be 0,5 MW, which is classified in the medium-power range.

    "This would be the equivalent to 450-500 homes average consumption", says Soto, who adds: "This kind of installation would avoid the emission of 140 tons of CO2 per year, an amount that represents the depuration effect of about 7.200 trees".

    This research has been promoted by the Canarian company ZECSA. Researchers from Vigo University have taken part to analyze the electrical connections needed to develop the project, along with other researchers from Las Palmas de Gran Canaria University, who were in charge of the integration in the scope of renewable energies ".

    In fact, the study has been published in the Renewable and Sustainable Energy Reviews and it is framed in PAINPER, a public infrastructures exploitation plan to boost the use of renewable energies.

    "PAINPER is an initiative which emerges from the difficulties seen in the implantation of this kind of energies in heavily built-up territories, as well as protected areas with low available space for new installations", says Aday C. Martín, manager at ZECSA, who considers that renewable energy produced in wind turbines under viaducts could be added to energy from other wind, solar, geothermal and biomass installations.

    Rooftop solar, battery storage to dominate Australian grid


    Rooftop solar and battery storage will account for more than half of Australia’s electricity needs by 2040, reducing the need for fossil fuel generation, as the share of fossil fuels falls by more than half to around 40 per cent.

    Bloomberg New Energy Finance says Australia’s power sector will fundamentally change over the next two decades, as households and businesses turn to rooftop solar and storage and utilities shift to renewables to replace ageing coal and gas plants.

    It is part of a massive global shift, with more than $3 trillion being invested in small-scale solar and battery storage worldwide, as the global energy system becomes largely decentralised.

    The report predicts more than 50 per cent of Australia’s generating capacity will be located “behind the meter” by 2040, meaning that consumers will become “pro-sumers”, generating and consuming their own electricity. BNEF predicts 37GW of small-scale solar PV – mostly on rooftops – and 33GW of battery storage will be installed by then.

    Wind power generates 140% of Denmark's electricity demand

    Unusually high winds allowed Denmark to meet all of its electricity needs – with plenty to spare for Germany, Norway and Sweden too


    So much power was produced by Denmark’s windfarms on Thursday that the country was able to meet its domestic electricity demand and export power to Norway, Germany and Sweden.

    On an unusually windy day, Denmark found itself producing 116% of its national electricity needs from wind turbines yesterday evening. By 3am on Friday, when electricity demand dropped, that figure had risen to 140%.

    Interconnectors allowed 80% of the power surplus to be shared equally between Germany and Norway, which can store it in hydropower systems for use later. Sweden took the remaining fifth of excess power.

    “It shows that a world powered 100% by renewable energy is no fantasy,” said Oliver Joy, a spokesman for trade body the European Wind Energy Association. “Wind energy and renewables can be a solution to decarbonisation – and also security of supply at times of high demand.”

    Buffett Scores Cheapest Electricity Rate With Nevada Solar Farms


    Warren Buffett’s Nevada utility has lined up what may be the cheapest electricity in the U.S., and it’s from a solar farm.

    Berkshire Hathaway Inc.’s NV Energy agreed to pay 3.87 cents a kilowatt-hour for power from a 100-megawatt project that First Solar Inc. is developing, according to a filing with regulators.

    That’s a bargain. Last year the utility was paying 13.77 cents a kilowatt-hour for renewable energy. The rapid decline is a sign that solar energy is becoming a mainstream technology with fewer perceived risks. It’s also related to the 70 percent plunge in the price of panels since 2010, and the fact that the project will be built in Nevada, the third-sunniest state.

    “That’s probably the cheapest PPA I’ve ever seen in the U.S.,” Kit Konolige, a utility analyst at Bloomberg Intelligence in New York, said Tuesday. “It helps a lot that they’re in the Southwest when there’s good sun.”

    The power-purchase agreement for energy from First Solar’s Playa Solar 2 project was the cheapest offered to NV Energy this year for new power plants. The utility also agreed to pay 4.6 cents a kilowatt-hour for power from SunPower Corp.’s 100-megawatt Boulder Solar project, the best price offered last year.

    Both 20-year, fixed-rate contracts were submitted to Nevada’s Public Utilities Commission for approval July 1.

    “When compared to existing solar contracts and to other fossil-driven generation,” the rates are “very reasonable,” the utility said in the filing.

    Belize to adopt 100% renewables plan

    The Caribbean nation of Belize is aiming to use renewable energy to source 100 per cent of its energy needs.

    The announcement follows the country’s decision to join the Carbon War Room’s high profile Ten Island Challenge.

    The new target will see Belize source 89 per cent of its electricity via clean energy resources by 2033 with the longer term goal being 100 per cent.

    The new plan will see a scaling up of wind energy infrastructure complementing the country’s substantial hydropower.

    Energy efficiency retrofits will also be a central part of the new plan.

    The Belize Ministry of Energy, Science & Technology and Public Utilities’ representative Senator Joy Grant said: “Belize is extremely pleased to join the Ten Island Challenge. As a regional leader in the use of renewable energy, this partnership with the Carbon War Room and Rocky Mountain Institute will allow Belize to make significant strides in realizing its renewable energy production target of 89 per cent in the electricity sector by 2033.”

    Belize currently receives about 60 per cent of its electricity via hydroelectric and biomass and the other 40 per cent is supplied via fossil-fuel-fired power plants and generators.

    The Ten Island Challenge was started by the Richard Branson backed environmental NGO The Carbon War Room, with the Rocky Mountain Institute and the Clinton Climate Initiative.

    World’s first all-electric ferry running 365 days per year in Norway


    The world’s first all-electric battery-powered ferry is now running 365 days per year in Norway.

    The emission-free Ampere ferry won the “Ship of the Year” award at the SMM trade show in September last year and secured a 10-year license to operate the Lavik-Oppedal route in south-west Norway beginning in 2015.

    The vessel has an all-electric powertrain, with two electric motors each with 450 kilowatts of capacity.

    The ferry has a capacity of 120 cars and 360 passengers and travels at about 10 knots.

    Good to see we are getting there. Had a look into the companys website and there are great advances in not only solar cell design but also on how they are assembled into deployable arrays. That last part was always too expensive so far.

    Now if battery storage becomes at least 3-5 times cheaper solar energy will become fully competetive.

    Edit: Whenever I saw solar panels for roof mounting and solar farms I did shake my head in disbelief. They all looked like confectioning them for installation was more expensive than the cells themselves. And it only got worse with declining prices for the cells. These cells address that problem, I like it.

    New superconductor-powered wind turbines could hit Australian shores in five years

    Australian scientists are developing wind turbines that are one-third the price and 1,000 times more efficient than anything currently on the market to install along the country's windy and abundant coast.

    New superconductor-powered wind turbines could be installed off the coast of Australia within the next five years to finally take advantage of the country’s 35,000 km of coastline, which offers up some of the best wind resources in the world.

    Developed by a team at the Institute for Superconducting and Electronic Materials at the University of Wollongong in New South Wales, the wind turbines are a significant improvement on current technology. Right now, wind turbines cost about $15 million each to construct, and are super-heavy and tough to ship. They also require a whole lot of maintenance because they're run using a complex, heavy, and costly piece of machinery called a gear box.

    “In our design there is no gear box, which right away reduces the size and weight by 40 percent,” said lead researcher and materials scientist Shahriar Hossain. “We are developing a magnesium diboride superconducting coil to replace the gear box. This will capture the wind energy and convert it into electricity without any power loss, and will reduce manufacturing and maintenance costs by two thirds.”

    Superconductors are a class of materials that have been getting a lot of attention this year due to their potential to completely revolutionise power systems and batteries as we know them. Right now, these systems generate power by running an electric current through a copper conduction loop, but during this process up to 10 percent of the energy is lost due to resistance. This, and the fact that the copper wire decays quickly, means our current power systems are relatively inefficient with short lifespans.

    But superconducting materials generate no electrical resistance, which means they're able to store electricity with no loss of energy. The current is also able to circulate over and over indefinitely, even if power is turned off. The Australian team is making their superconducting coil out of magnesium and boron, both of which are cheap, durable and easy to make.

    The team estimates that their superconductor wind turbines will cost just $3-5 million each to build, because by next year, the magnesium diboride coil will cost just $1 per metre to manufacture.

    “Australia desperately needs sustainable energy sources. Wind is cheap, clean and we can get it on rainy and sunny days,” he said. "And considering Australia has more than 35,000 km of coastline, there is ample room for offshore wind farms. With industry support, we could install superconducting offshore wind turbines off the coast of Australia in five years, no problem.”


    They better start building a distribution system now if they plan on using this source of electricity. Having a home near the Columbia river gorge I pass by hundreds of wind turbines regularly, many of these turbines never turn as the electrical distribution system from the turbines to the grid will not handle nearly full electrical production.

    Time for an update. I started this thread with a Tesla in the first post. It has been modified, somewhat.

    Tesla's New 762hp Model S P90D With ‘Ludicrous’ Speed Upgrade Does 1/4 Mile In 10.9 sec!


    So Tesla has been trying to find a way to make the Model S P85D even faster, like there was an actual person thinking that the electric bi-motor slingshot needed a stronger kick.

    Elon Musk announced the new ‘Ludicrous’ Speed Upgrade for the P90D, which makes the Internet’s favorite drag-racer 10% faster from zero to 60mph, now scoring a 2.8 seconds with a quarter mile time of 10.9 seconds!

    That’s right; the Model S P90D ‘Ludicrous’ is now officially a 10-second car with Elon Musk saying that his new toy can achieve 1.1g during acceleration, which feels faster than falling.

    They are a bit concerned,……from Alberta Oil

    Is Tesla’s Model-S the Beginning of the End for Oil?

    Why battery technology could drive the electric vehicle to new heights – and disrupt the fossil fuel industry in the process


    The Tesla Model-S is one of the most beautiful and interesting automobiles to ever get made. It might also be one of the most dangerous. That’s because it’s managed to do something that no other electric vehicle has ever achieved: become an object of desire. Previous generations of electric cars, from the Nissan Leaf to GM’s famous (and infamous) EV-1, have tended to be high on cost and low on drivability. But the Model-S managed to bridge that divide, and as the reviewers at Car and Driver said in their review of the car, “it dispels conventional thinking about EVs – it’s a glimpse of the future.”

    Surprising Countries Where Solar and Wind Are Booming

    Renewable energy is taking off in both wealthy and developing economies.


    Across the globe, renewable energy is expanding faster than fossil fuels. It’s even taking off in countries that may surprise you.

    “Once again in 2014, renewables made up nearly half of the net power capacity added worldwide,” says Achim Steiner, executive director of the United Nations Environment Programme. After a two-year dip, they’re attracting more investment. Hydropower generates the largest share of renewable energy, followed by wind and biomass, but solar is growing the fastest.

    Some countries are obvious leaders. The U.S. and China had the greatest installed capacity for producing power from wind in the last two years, while Germany and China had the most from solar panels, according to the U.S. Department of Energy and Ren21, an international nonprofit group.

    Envision Solar, a renewable energy and electric vehicle charging company based out of San Diego, has been awarded a contract in the State of California to provide portable electric vehicle (EV) chargers to various state and local government agencies, according to a recent email sent to CleanTechnica.

    The contract — which is a part of the climate change–related plans announced by re-elected Californian Governor Brown in January — will allow essentially government employees in the Pacific state to recharge their EVs at work using solar energy, if so desired.

    5 Bold and Beautiful Solar Projects From Around the World

    China is building its largest solar plant covering 6,301 acres in the Gobi desert and with capacity to provide electricity to 1 million households.

    This is just another record breaker for China. But there’s good reason.

    In a recent Greenpeace East Asia investigation, we found that air pollution levels have improved in the first six months of 2015, though still remain below global and domestic standards. Once completed the new solar plant will cut standard coal use by 4.26 million tons every year, reducing emissions of carbon dioxide and sulfur dioxide by 896,000 tons and 8,080 tons, respectively, according to state-run Xinhua news agency.

    Looking more like a enlightened being bursting from a holy church, this tower which sits at Sanlucar la Mayor outside Seville, Spain can provide electricity for up to 6,000 homes.

    2. Solar Systems on Hospital in Bihar: India


    At Tripolia Hospital, Patna, India they have installed simple concentrated solar power (CSP) systems to create steam, which they use to sterilize all their medical equipment and laundry. The hospital also has solar photovoltaic systems to generate electricity for some buildings and outdoor lights and solar thermal systems to create hot water for bathing patients and preparing medicine. The various solar systems also cater for the 200 staff who live on campus, as well as up to 250 inpatients.

Parama lives above the plant and is one of its biggest advocates, personally persuading 100 of the 150 families that now collect the ‘sweet’ water to trust that the system was clean. Like many of the villagers, he would often have to drink the saline ground water before the plant was installed.

    I look at the huge roof areas of the industrial estates and wonder why they are not putting solar panels on them to produce their own power. Rather than take up land to generate power from the sun why not use roof areas, particularly large ones ?

    We do a fair bit of camping sometimes in places where there is no power so the lady boss has just bought one of these:



    Panel is 10 X 8 cm and the boss tells me it charges her phone very quickly.
    No need for any installation just sit it in the sun somewhere and the battery will be charged as will anything connected to it.



    The back showing the small battery, light on the right and plug for charging on the left.

    This set up is self contained and is put together by kids from a local school for disadvantaged kids and is sold to help pay for the school.

    starting with the answer again, gets it wrong everytime

    Chinese state owned businesses massively pilled into solar tech, using loans from state banks without the need to worry about paying the money back. This created massive over supply, resulting in all these firms selling below cost in china and abroad. This is classic dumping, distorts the market in the short term, destroying indigenous businesses and doing long term damage to europe, the tarrifs were introduced to level the playing field.

    back in china the situation got so bad with these firms that china experimented with their first bankruptcy to reduce over capacity, they drew up a list of 12-14 firms who could continue to get loans from state banks.... the rest were denied access to bank loans and well disappeared.


    as a side issue, I am still skeptical about the use of solar panels in urban environments.
    their manufacture is very energy intensive and I am not convinced in that in an urban setting when one considers the the carbon footprint of their whole life cycle... that the carbon emissions avoided from the electricy they generate greatly exceeds the emissions created from their manufacture.

    New design brings world's first solar battery to performance milestone


    After debuting the world's first solar air battery last fall, researchers at The Ohio State University have now reached a new milestone.

    In the Journal of the American Chemical Society, they report that their patent-pending design--which combines a solar cell and a battery into a single device--now achieves a 20 percent energy savings over traditional lithium-iodine batteries.

    The 20 percent comes from sunlight, which is captured by a unique solar panel on top of the battery, explained Yiying Wu, professor of chemistry and biochemistry at Ohio State.

    The solar panel is now a solid sheet, rather than a mesh as in the previous design. Another key difference comes from the use of a water-based electrolyte inside the battery.

    Because water circulates inside it, the new design belongs to an emerging class of batteries called aqueous flow batteries.

    "The truly important innovation here is that we've successfully demonstrated aqueous flow inside our solar battery," Wu said.

    As such, it is the first aqueous flow battery with solar capability. Or, as Wu and his team have dubbed it, the first "aqueous solar flow battery."

    "It's also totally compatible with current battery technology, very easy to integrate with existing technology, environmentally friendly and easy to maintain," he added.

    Japan has started turning abandoned golf courses into solar power plants


    During real estate booms, developers have a tendency to build more than is necessary. When those booms go bust, we get to sit back and watch as people come up with creative uses for all that waste.

    This is what’s happening in Japan, where developers built too many golf courses over the last few decades after demand shot up in the 1980s. Now the industry is in decline, with participation in the sport down 40% from the 1990s, and abandoned golf courses are starting to pop up.

    Kyocera’s solution: turn the abandoned green space into solar farms. Japan has been hungry for alternative energy ever since the 2011 Fukushima disaster made nuclear power an unattractive option in the country, and golf courses just happen to be perfectly suited for solar power — they’re large open spaces that often get lots of sunlight.

    World’s First Integrated Geothermal and Biomass Plant Goes Online


    Enel Green Power has announced the completion of a 5 megawatt (MW) biomass power plant in Italy’s Tuscany region that integrates biomass with geothermal steam generation.

    A first of its kind, the newly constructed biomass plant will use locally sourced virgin forest organic matter and a “super-heater” boiler to increase steam temperatures at the nearby 13-MW Cornia 2 geothermal plant. Geothermal steam temperatures entering the Cornia 2 plant will be raised from 300 degrees to over 700 degrees (Fahrenheit). The result, according to Enel Green Power, will be an increase in the geothermal plant’s net electricity generation capacity.

    It is projected that the integration of the biomass plant will boost the overall Cornia 2 geothermal plant output by some 30 gigawatt hours (GWh) a year. It will also mitigate the emission of 13,000 tonnes of CO2 annually. This innovative technological approach will result in minimal local environmental impact and secure “total renewability” within the resources used and the cycle of energy generation.

    ^ Tepco has a hydro power dam at the bottom of the hill from my house in Gunma-ken, Japan. Tepco has now put in solar panels and battery banks all around that area so they are generating both kinds of power from that facility.

    Will also mention the thousands of logs pulled from the water at that dam site. I asked my husband why they were being left to rot and not used for building or firewood. He said they were toxic from the Fukashima fallout and could not be used. Yikes. This is far from Fukashima.

    I wonder how they compare to the latest version of the Tesla Model S



    Tesla Motors delivers ?ludicrous speed upgrade? for Model S P85D | ExtremeTech

    Model S beats Formula 1 racecars at the 0-100km/h sprint.

    Revolutionary tidal fence is set to trap the sea’s power


    A British company has announced plans for an array of unique marine turbines that can operate in shallower and slower-moving water than current designs.

    Kepler Energy, whose technology is being developed by Oxford University’s department of engineering science, says the turbines will in time produce electricity more cheaply than off-shore wind farms.

    It hopes to install its new design in what is called a tidal energy fence, one kilometre long, in the Bristol Channel − an estuary dividing South Wales from the west of England − at a cost of £143m.

    The fence is a string of linked turbines, each of which will start generating electricity as it is completed, until the whole array is producing power. The fence’s total output is 30 megawatts (MW), and 1MW can supply around 1,000 homes in the UK.

    Peter Dixon, Kepler’s chairman, told Reuters news agency: “If we can build up to, say, 10km worth, which is a very extended fence, you’re looking at power outputs of five or six hundred megawatts. And just to visualise that, it’s like one small nuclear reactor’s worth of electricity being generated from the tides in the Bristol Channel.”

    The World’s First Floating Wind Farm


    Two weeks after passing a law that completely re-envisions the country’s energy system, France is already making moves to bolster its wind potential by inviting companies to submit proposals for floating wind farms off both its northern and southern coasts.

    On Wednesday, France’s environmental agency ADEME posted a tender document calling for proposals for wind farms comprised of between three to six turbines, with the capacity for at least five megawatts per turbine, at three sites in the Mediterranean and one site in the Bay of Biscay, off the southern coast of Brittany.

    The call is part of a push by the French government to encourage the transition of France’s energy system from one that relies heavily on nuclear to one that produces at least a third of its energy through renewable technology. Monetary investments from the French government will come from the “Investments for the Future” program launched in 2010. According to Reuters, the government has made 150 million euros ($163.53 million) available for the project, a third as investment subsidies and two-thirds as loans.

    Largest Solar Rooftop In Colombia To Be Built By Solarcentry & Hybrytec


    Solarcentury has teamed up with Colombian company Hybrytec to build the country’s largest solar PV roof system, atop Exito’s Barranquilla store.

    Solarcentury is one of the oldest solar companies in the world, and Hybrytec is a Colombian company leading the local solar energy market, with 7 years experience and over 140 projects successfully completed across the country. The two companies managed the whole development process of the record-breaking rooftop solar project, from initial design through to construction and on to operation and maintenance.

    Aerial-viewThe resulting 507 kW rooftop solar installation is the largest in Colombia, covers 6,300 square metres, and is made up of 2,070 solar panels. The solar installation is set to reduce the Exito Barranquilla store’s annual energy bills by about 24%, and will reduce carbon emissions by about 23o tonnes per year.

    First Large Scale Solar Power To Be Built In China's Gobi Desert


    Though China is the world’s largest greenhouse gas producer, the country is making a solid effort to commit to renewable energy, including building a solar power plant in the Gobi desert.

    With construction officially on the way, this will be the first commercial power plant built on such a large scale.

    A joint venture between California-based BrightSource Energy and the Shanghai Electric Group, the plant will span across 25 square kilometers (nearly 10 square miles) of unused land in the Qinghai province, generating 200 megawatts of power. "Its designed heat storage is 15 hours, thus, it can guarantee stable, continual power generation," said Wu Longyi, board chair of the Qinghai Solar-Thermal Power Group, in a statement.

    This new solar plant means that China will cut coal use by 4.26 million metric tons (4.69 million tons) every year, reducing the country’s annual carbon dioxide emissions by 896,000 metric tons (987,671 tons) and sulfur dioxide emissions by 8,080 metric tons (8,906 tons).

    As the world’s biggest investor in renewable energy, the country’s capacity for generating solar has been increasing fast towards its aim of generating 100 gigawatts of power by 2020.

    Another idea that I saw in Huai Kha Khaeng wildlife sanctuary. This sits in a flowing river bed and the river flow turns a turbine producing power. No need for dams. All in Thai unfortunately. More on these here : https://en.wikipedia.org/wiki/Gravit...ex_power_plant

    Oversimplified memo from European solar panel manufacturers association.

    Now for environment's sake lets buy and use all available cheap solar panels Chinese sell under production cost shall we?

    "indigenous businesses " Chinese solar tech is more advanced than European, which brings us again to German 50's tech and EU pushing tariffs to protect Fortress Europe against bad foreigners at expense of environment. And the world, it wont stand still...

    Who will build solar panels for the sake of the environment in future, if companies have to close due to Chinese short-term price dumping, genius?

    Btw, you misunderstood the term "indigenous", you need to improve your English skills.

    Same people who will manufacture everything else? As in free market economy?

    Silly boy, you need to improve your English skills.
