    Italy could soon make Europe Solar powered

    pannelli-solari.jpg
    No one knows lighting like the Italians, its no wonder that the best chandeliers are from Italy. The countries energy requirements are rising, like the rest of the world, but it hasn’t been able to get on the solar power bandwagon yet. The hindrance has so far been the confusion over prices and maintenance cost involved. However the mayor in a small town in Milan has managed to light up a cemetery with a photovoltaic plant composed of 18 solar panels, providing the cemetery with free lighting and saving 20% on the billing cost. Enel SpA, Italy’s largest utility, and Sharp Corp., a leader in solar power technologies have joined hands to set up joint solar power generation plants in Italy, which are expected to have an output capacity of more than 160 megawatts by the end of 2011 and supply 81.500 Italian families with energy.

    hydrowind_main.jpg
    State-controlled Norwegian oil company StatoilHydro has decided to build the world’s first full scale floating wind turbine, Hywind, and test it over a two-year period offshore Karmøy. StatoilHydro has developed HyWind based on floating concrete constructions familiar from North Sea oil installations. The rotor blades on the floating wind turbine will have a diameter of 80 metres, and the nacelle will tower some 65 metres above the sea surface. The floatation element will have a draft of some 100 metres below the sea surface, and will be moored to the seabed using three anchor points. The wind turbine can be located in waters with depths ranging from 120 to 700 metres.

    Data centers switch to intelligent switches

    data-center-1.jpg
    Not everyone knows about the massive amount of energy that is needed to keep websites online and active. In 2006 U.S. Servers and Data Centers Gobbled Up 61 billion kWh, now that’s a lot considering that most users that time didn’t go beyond checking their emails and maybe watch a few YouTube videos. Today however YouTube isn’t a recent discovery, it now has many competitors diving for attention. Microsoft Research’s Networked Embedded Computing group is working on a very promising concept: A combination of physical sensors in the server room and software algorithms to make individual computers sleep or wake up depending on demand.

    Korean Village 100% solar powered

    solar_power_village_1.jpg
    While most of us are happy having a solar cell in our calculators and often dream of owning enough solar cells to power our home, a small village in Korea has already done it. The village Donggwang gets 100% of its power from the sun. The village is located on the semi-tropical island of Jeju-do. Near the village, Halla Mountain, a volcano and the tallest mountain in South Korea, rises from the island’s center amidst a patchwork of small farms. The village’s forty houses and the school all have large solar panels covering their roofs. A typical roof will have a two kilowatt solar installation. In 2004, the government subsidized the solar systems in Donggwang, paying 70% of the installation fees. Now if only our govt realizes the harm to the environment the older forms of energy production make and lose its selfish obsession with making money providing the most basic of energy requirements.

    Google invests $20 million into renewable energy

    reenergy.jpg Alternate energy is the coolest rage today, but not everybody has the capacity to make money out of it. Unless of course you are Google! Google is now planning into the energy business, and as any of its previous ventures its going to do it in a big way. It already has a history of investing in renewable energy, with its Mountain View, Calif. headquarters already being powered, in part, by one of the largest solar electric installations in the United States. It now plans to go big with its philanthropic arm, Google.org, and invest $20 million in the next year alone toward renewable energy research. This will include the cost of hiring between 20 and 30 new employees, including renewable energy experts. Google aims to find a way to significantly reduce the cost of renewable energy generation to bring it more on par with the cost of coal.

    Solar Brasserie from Japan

    tp_01.jpg
    Triumph International a leading lingerie manufacturer from Japan has produced the Solar Brasserie. The Bra has a solar panel which generates electricity and is in turned wired to a mini electric bulletin board for displaying messages. In addition to this the bra padding can be used to store water or vodka and to drink it a straw needs to be inserted into the brasserie cup. The brasseries is made using organic cloth (cotton grown without fertilizers and pesticides). Triumph International will not be selling this product anytime soon, thankfully.

    EFuel100 MicroFueler – Get your car high on tequila or sugar

    EFuel100_MicroFueler_1.jpg
    Finding an ethanol gas station may become a thing of the past since most of us can easily make it in our back yards. E-Fuel founder and CEO Thomas Quinn thinks that such a day is soon to be. It looks like a cross between a gas pump and an old-fashioned refrigerator, but in reality it’s a home ethanol refinery. Connect it to a power source and a water source, add sugar “feedstock” and yeast or discarded alcohol (yes, that could mean last week’s tequila) and in a week it can produce 35 gallons of ethanol that Quinn said any car can run on.

    Singapore launches new scheme to encourage using solar technologies

    Singapore.jpg
    The Singaporean government launched a new Solar Capability Scheme on Tuesday to encourage the private sector to install solar technologies in new building projects, local media reported. The new scheme, announced by Singapore’s Economic Development Board (EDB), was the Clean Energy Program Office’s latest program. The scheme encourages innovative design and integration of solar technologies into energy efficient buildings. It applies to new building developments in the private sector which meet the required standard. The private sector can get total about 14.7 million U.S. dollars to offset part of the capital costs of installing solar energy technologies.

    Weeds, algae and solar energy could soon power Britan’s Military

    Algae.jpg
    Britain’s armed forces are planning to end the military dependency on fossil fuels. Possible innovations include unmanned attack aircraft powered by the sun. They would fire missiles fuelled with hydrogen produced by feeding algae to microbes. Tanks could be electrically powered or run on fuel produced from oil squeezed out of weeds so hardy they can grow in the desert. Ships could run completely on electricity produced from generators powered by synthetic fuels made from grass. The environmental requirements of the army, navy and air force will be presented this week to specially vetted defence and research companies. The Ministry of Defence (MoD) said last week that many of the ideas would come to fruition only in the next generation. The US Air Force, however, is expected to start converting its aircraft to use a mix of synthetic and petroleum-based fuel by the end of 2010 and the RAF is likely to follow suit. The Royal Navy’s new Type45 destroyers already use all-electric propulsion, albeit produced by gas generators, and greener ways of producing the electricity are being explored in conjunction with the French. Turning all three services “green” was one of a number of new defence targets outlined last week by Paul Stein, the MoD’s science and technology director, to the Royal Aeronautical Society in London. Others included more unmanned, missile-carrying aircraft; lightweight tanks; ultra-light equipment for soldiers and futuristic communications devices. While some of the plan will be made public, most will be made available on a secure website to selected company and university research departments. “It will provide clear direction to the research and development community,” the ministry said.

    eSolar – A DIY solar power plant

    eSolar.jpg Soon setting up a solar power station is to get a lot more user friendly and a new technology could change the solar industry. IKEA changed the rules for furnishing a home. The eSolar power plant is based on mass manufactured components, and designed for rapid construction, uniform modularity, and unlimited scalability. Each eSolar module, though, is designed to generate 33MW of power — enough juice to power 10,000 homes. If you need 330MW, you just buy ten modules and put them together. It’s not exactly flat-pack home furnishings, but it’s the same world-changing idea. Presumably, you’ll need more tools than those little Allen wrenches and nifty fasteners IKEA supplies with its furniture. However, you don’t need the heavy equipment, cranes and trained engineers now required to put traditional thermal power plants together: eSolar has replaced expensive steel, concrete, and brute force with inexpensive computing power and elegant algorithms. This new method of installing a solar power plant minimizes costly civil construction and the use of heavy equipment, dramatically reducing project cost and deployment time. That’s a big claim when you consider that a 33MW modular plant needs 160 acres of land — about 1/4 of a square mile. It’s still a job for a trained construction crew that knows what to do when they open the eSolar box. Inside are many identical towers and thousands of small mirrors — each about a meter square in size — engineered back in eSolar’s manufacturing plant — to essentially snap together. At least that’s how it seems after talking to eSolar executives, who are playing the details very close to the chest. They’re promising to show off a portion of a module at a demonstration facility somewhere in Southern California before the end of this year. eSolar says solar energy that is cheaper than coal is the goal. The company isn’t yet ready to divulge the cost of a module, but claims that right now, its solution is competitive with natural gas, which can produce electricity for 9 cents a kilowatt-hour. Between the rising price of both gas and construction,
