    Delaware Coast to get Offshore Wind Power Farm

    wind_power.jpg
    Bluewater Wind, an offshore wind power company has won the contract to build America’s first offshore wind turbine park off the coast of Delaware. Using electricity generated by the wind, “Delmarva Power will be able to light about 50,000 homes a year, every year” for the duration of the 25-year contract, with first power expected by 2012. The project may help stabilize consumer energy costs, since the contract locks in the price Delmarva will pay per kilowatt-hour. Each turbine sits on a pole about 250 feet above the waterline. The units will be constructed in such a way that it will withstand hurricane-force winds. Each blade on the three-blade rotor is to be 150 feet long.

    Britain’s first eco-nightclub needs peppy dancers to generate electricity

    eco-nightclub_1.jpg The DJ of this new eco-nightclub better play great music if he wants to keep his turntable working. For if the feet stop thumping so will the power. Britain’s first eco-nightclub, set to open in King’s Cross, will require the patrons to dance on a modified dance floor that will harness the energy expelled by the clubber’s moves and convert it to electricity. This place is so Green-oriented; they even plan on using a recycled water system to flush their lavatories. The Club will also serve organic spirits served in polycarbon cups. Entry to the club will cost £10, but those who can prove that they cycled, used public transport or walked to the venue will be welcomed in free. That’s not it customers will have to sign a pledge before entering the club that they will work towards curbing climate change.

    TGER – Turning trash into precious fuel

    TGER_on_station_540x404.jpg
    Trash, as it turns out, is an attractive feedstock. There are several commercial companies developing technologies that use wastes as fuel. The military currently burns its trash in incinerators, emitting icky emissions and eating up a lot of fuel, time, and human power since it takes quite a few people to run one. Also, cutting down on the use of diesel fuel is especially important since the trucks that haul the fuel are basically moving targets sure to make huge bangs. They have developed a prototype generator that uses trash as fuel to generate power. The generator is called TGER (“tiger”) and the acronym stands for Tactical Garbage to Energy Refinery. The prototype, which uses a variety of technologies to run an electrical generator, will be tested until August. The purpose of the unit is to cut down on the amount of diesel fuel used and to cut down on the amount of garbage that camps generate, which are security risks. The wet and dry wastes are separated. The dry trash is crushed, pelletized, and fed into a gasifier where the pellets are heated until they’re turned into synthetic gas, which then fuels the generator. The wet waste is converted with the use to enzymes into hydrous ethanol, which is then blended with synthetic gas to boost the generator’s output to 55 kW.

    Gotwind – A Green PowerStation for hungry mobiles

    Orange Green power2.jpg
    Batteries dying out at multi-day events are not an unfamiliar sight today, but simply having a conventional power dispenser is not an easy option for event managers. To keep mobile phone users from avoiding such events, Mobile Operator Orange is working with a renewable energy company Gotwind, the recharge Pod is an evolution of the Orange portable wind charger, tested at 2007’s Glastonbury Festival. The recharge Pod will be stationed within the Pennard Hill camping grounds at Glastonbury and will be a free service allowing all festival goers to charge their mobile phones throughout the weekend. Over 7 meters in height, the free standing “recharge Pod” is a self sufficient unit that supports a wind generator and solar panels and can charge up to 100 mobile phones per hour.

    Rice Mill in California installs 1Megawatt solar array

    FAR_WEST_RICE,_CLOSER_AERIAL_.jpg
    Although the picture shows a totally cultivable land concretized and converted into a solar farm, this is somehow a green solution to the energy crisis that we face today. Far West Rice Mills in Nelson, Calif., on Wednesday dedicated a one megawatt solar array that will provide three-fourths of its electricity. The Global energy crisis have hit business bottom lines hard, that’s the reasons Corporations and agribusiness invest in these systems to get a predictable electricity price over several years, to keep a check against rising prices.

    US and India join hands for emission free power generation

    magick_USIndiaGreen.jpg
    The US and India both rely on coal for its power generation needs; the US has now initiated a 10 year joint venture to produce and share technology for emission free power between both countries. FutureGen is a $1Billion a year plan to build a zero-emission, coal-fired electric and hydrogen production plant. It aims to integrate advanced technologies in coal gasification, extracting hydrogen from coal, power generation, carbon dioxide containment, and geologic storage. Around 55% of India’s total power consumption is based on coal. Last year, 500 million tons of coal was used for power generation in India.

    Sapphire energy launches green crude

    Sapphire.jpg
    A start-up alternative energy firm has announced that it has found a way to convert sunlight, CO2 and microorganisms such as algae into gasoline. The San Diego, Calif.-based company also disclosed that it has raised $50 million from Arch Venture Partners, Venrock, and the Wellcome Trust. The company, they say, started with 3 friends discussing a very interesting question: “Why is the biofuel industry spending so much time and energy to manufacture ethanol — a fundamentally inferior fuel?” The friends – a bioengineer, a chemist, and a biologist – set out to recruit the best minds they could find to collaborate with them on the project, and the results speak for themselves. They developed a unique platform using sunlight, CO2 and microorganisms such as algae” to produce the fuel, without the use of arable land.

    Siemens to soon open its first US wind R&D centre

    siemens_logo.jpg Siemens Energy will be soon opening its first U.S. based wind turbine R&D competence center in Boulder, Colorado. The facility is expected to employ an estimated 50 people and will focus on atmospheric science research, aerodynamic blade design, structural dynamics, wind turbine dispatch prediction and reliability. The new Siemens R&D Center is expected to create 12-15 green-collar positions in the first year, followed by 5-10 additional careers every year thereafter, resulting in approximately 50 new positions by 2013. Most employees will be new hires with a PhD or master’s degree in the desired disciplines.

    Shell stations to be soon pumping hydrogen

    hydrogen_fuel.jpg The fuel crisis has many switching to the alternative transport solutions, but finding a station that sells hydrogen or is capable to charge your electric vehicle in a jiffy is very rare. That could soon change as Shell is planning to sell hydrogen fuel from its gas stations in LA, as part of a research program run by the US Department of Energy in conjunction with GM. Shell’s hydrogen is created on-site with an electrolyzer, but all parties agree that this is only a short-term solution. Shell will build a few more stations on its own in the next few months, and they will be part of “mini networks” of hydrogen filling stations that will hopefully help spark mass production of fuel cell vehicles. These are needed in big cities since the only emission would be water, but paradoxically, the source for the hydrogen is fossil fuels.

    ElectraTherm – Green energy generated from industrial heat

    electratherm_green_machine.jpg The options we have now-a- days for alternate energy seem to be expanding at a fierce pace. A typical home solar installation can generate between two and four kilowatts, while Google’s solar array at its corporate headquarters–considered the largest in the U.S.–is 1.6 megawatts. Now a company called ElectraTherm has developed a 50-kilowatt machine that uses industrial waste heat as its “fuel.”The machine uses an organic Rankine cycle to heat liquids which are turned into a vapor that turns a turbine to make electricity. The thermoelectric effect has been known since the early 19th century. But the idea of making electricity from heat appears to be getting more attention.
