    For those who still think that electric powered vehicles have a long way to go, think again. The Vectrix is a very powerful electric powered scooter that accelerates faster than cars at stop signs and claims to go upto 68mph at top speed. The Vectrix is powered by a low-mounted, 3.7 kilowatt NiMH battery pack that re-charges to 80 or 90 percent of capacity in two hours. Three hours is usually enough for a full charge, four if you start from flat empty.

  • Korean Village 100% solar powered

    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

    Posted in Uncategorized on May 22, 2008

    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.

    Komatsu PC200-8 Hybrid World’s 1st Hybrid Excavator

    Komatsu PC200-8 Hybrid hydraulic excavator combines a capacitor and a diesel engine. While construction machines normally use hydraulic motors to turn their upper structures, Komatsu’s new Hybrid model uses an electric motor for this movement. The electric motor collects energy generated when the upper structure of the excavator slows down while turning. The energy collected is converted into electric energy to be stored in the capacitor. The stored electricity is utilized via a dynamo-electric motor to assist the engine when it is accelerating. As a result, the engine can be used in a low-rotation zone with high-efficiency combustion. In addition, the rotation can be maintained at 700rpm when the engine runs idle (during deceleration), thereby reducing the fuel consumption.

    Toyota Prius Sales Top 1 Million Mark

    Toyota has announced today that worldwide cumulative sales of the Toyota Prius have passed the 1 million mark, with approximately 1,028,000 units sold as of the end of April this year. The Prius was launched in Japan in 1997 and began selling in Europe, North America and other markets in 2000. In 2005, Toyota began first overseas production of the Prius in Changchun, China, and sales of Prius vehicles in South Korea are expected to begin in the latter half of 2009. Based on sales figures and a lot may complex calculations Toyota claims Prius’s have led to a reduction in CO2 emissions (considered a cause of global warming) by producing approximately 4.5 million tons less CO2 when compared with gasoline-powered vehicles in the same class and of similar size and driving performance.

    Web to go green in energy generation

    Posted in Uncategorized on May 14, 2008

    data_center-1.jpg
    What do you think are the big internet companies doing when they say they are going green? One single Google search query consumes 2 to 8 watt-hours of energy. To put this on a scale, Google processes petabytes of information on a daily basis while indexing the web and doing other various things. If we average this out to 4.5 watt hours per query, and consider Google is easily handling 400 million queries a day based on comScore metrics, then we can see 1,800,000,000 (1.8 billion) watt-hours of energy being used daily just for basic search queries. When a big company like Intel or Google refers to “greening” or “going green” with their server technologies the first step is finding a renewable or more efficient power source. Generally wind-power and biomass come to mind, but we’re going to need more than that to power the web as you can already see. You have to remember that a website like Youtube doesnt just rely on some hard disks spinning in some guys dorm. The amount of heat produced by these data centers is another intimidating issue we have to face… With the currently technology available we’re forced to use AC units and massive cooling centers to keep all of the servers at around 70 degrees or less. The hot air gets pumped out of the centers and usually outside, although some companies are finally using this excess heat to power office buildings and heat up pools in surrounding areas.

    Volkswagen AG along with Japan’s Sanyo Electric is in the process of developing a lithium-ion battery, a key component of hybrid and electric cars. Sanyo is going through a restructuring and believes its battery business is key to its turnaround. Sanyo is currently manufacturing nickel-hydrogen batteries that can be recharged repeatedly and supplying them to Honda Motor Co. and Ford Motor Co. Volkswagen and subsidiary Audi AG will also adopt Sanyo-made nickel-hydrogen batteries for use in the Volkswagen group’s first hybrid model, to be rolled out as early as next year. Toyota, which has enjoyed enormous successes with Prius hybrid model, has worked with Matsushita Electric Industrial, known for its Panasonic brand, to start mass-production of a lithium-ion battery for use in Toyota’s hybrid models by 2010.

    EFuel100 MicroFueler – Get your car high on tequila or sugar

    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.

    Urban mining – more profitable than assumed

    Posted in Uncategorized on May 8, 2008

    cell_phones.jpg The demand for precious metals never will diminish; neither will the amount of people who hunt for these precious metals. There are a new breed of treasure hunters who hunt for precious metals in dumpsters and other wastelands; they are called the urban miners. Urban mining simply means scavenging through the scrap metal in old electronic products in search of such gems as iridium and gold, and it is a growth industry around the world as metal prices skyrocket. A ton of ore from a gold mine produces just 5 grams (0.18 ounce) of gold on average, whereas a ton of discarded mobile phones can yield 150 grams (5.3 ounce) or more, according to a study by Yokohama Metal Co Ltd, another recycling firm. The same volume of discarded mobile phones also contains around 100 kg (220 lb) of copper and 3 kg (6.6 lb) of silver, among other metals. Recycling has gained in importance as metals prices hit record highs. Gold is trading at around $890 an ounce, after hitting a historic high of $1,030.80 in March. The materials recovered are reused in new electronics parts and the gold and other precious metals are melted down and sold as ingots to jewelers and investors as well as back to manufacturers who use gold in the circuit boards of mobile phones because gold conducts electricity even better than copper. Japan’s 128 million populations use their cell phones for an average of two years and eight months. That’s a lot of cell phone phones discarded every year, yet only 10-20 percent are recycled as people often opt to store them in their cupboards due to concerns about the personal data on their phones , said Yoshinori Yajima, a director at Japan’s Ministry of Economy, Trade and Industry. Just 558 tons of old phones were collected for recycling in the year to March 2007, down a third from three years earlier, industry figures show.
