Who would ever have thought that wind blower fans in a cow barn would spark an idea to create innovated vertical wind turbines?
It turns out that a small, clean technology startup company located in a kibbutz near Ramat Hasharon, Israel may be developing a new stackable wind turbine that could compete with the giant propeller ones currently in use around the world.
Coriolis Wind is the brain child of its 3 co-founders Dr. Rafi Gidron, an entrepreneur from Precede Technologies, an entrepreneurship and investment firm focused on high growth markets such as alternative energy; Orni Petruschka, also with Preclude; and Dr. Shuki Sheinman, formerly connected with NASA, Scitex and El Op.

There are many advantages to wind power, the least of which is zero-emissions electricity. Now, several innovative companies worldwide are exploring the idea of creating floating wind turbines anchored to platforms far out to sea that connect to the seabed to harness the power of the ocean winds.
In September, the first full-scale floating wind turbine was launched in the North Sea off Norway. Called Hywind, the 2.3-megawatt wind turbine was hauled six miles out to sea by tugboats and installed on a floater traditionally used for production platforms and offshore loading buoys. The turbine’s tower is bolted to a steel cylinder that extends more than 300 feet below the surface and is connected to the seabed with three anchor points. (more…)

Living near wind farms does not pose adverse health effects, according to a new study.
The research, conducted by a seven-member panel of scientists from the Massachusetts Institute of Technology and other institutions, was funded by the American and Canadian wind industry associations.
The 85-page report says there is no medical basis for concerns that the audible or “subaudible” sounds of spinning wind turbines cause physiological harm to people who live nearby.

For years now, many members of Congress have insisted that cutting carbon emissions was difficult, if not impossible. It is not. During the two years since 2007, carbon emissions have dropped 9 percent. While part of this drop is from the recession, part of it is also from efficiency gains and from replacing coal with natural gas, wind, solar, and geothermal energy.
The United States has ended a century of rising carbon emissions and has now entered a new energy era, one of declining emissions. Peak carbon is now history. What had appeared to be hopelessly difficult is happening at amazing speed.
For a country where oil and coal use have been growing for more than a century, the fall since 2007 is startling. In 2008, oil use dropped 5 percent, coal 1 percent, and carbon emissions by 3 percent. Estimates for 2009, based on U.S. Department of Energy (DOE) data for the first nine months, show oil use down by another 5 percent. Coal is set to fall by 10 percent. Carbon emissions from burning all fossil fuels dropped 9 percent over the two years.

Turkey’s alternative energy potential is huge, but it remains locked – at least so far. Earlier this month, Ankara hosted the International Energy Congress on Renewable Energy where the Turkish energy sector was the main discussion point. The congress attracted a record number of participants from public and private sectors, including the Turkish Minister of Energy and members of the country’s Parliament. It was once more observed that the potential of investments in Turkey is by far exceeding the enthusiasm of the bureaucrats and the readiness of the Turkish infrastructure.

A recent Jewish Telegraphic Agency article by Dina Kraft on clean technology takes a good look at a number of projects by Israeli clean tech industries and Israel’s military branches in the realm of renewable and alternative energy.
“Beating swords into green plowshares in Israel,” the article talks about solar energy energy companies such as Bright Source Energy, which is involved in building solar energy plants in California’s Mojave Desert and other locations; and Rotem, which utilizes technologies developed in Israel’s aeronautical defense industry.

A battle over whether to place wind turbines within sight of France’s famous abbey, Mont-Saint-Michel, has touched off a dispute within the country’s environmental community over the visual impact of the alternative energy source.
A coalition of local and national conservationists has opposed locating the wind turbines within view of the abbey on the Normandy coast, even though the windmills would be roughly 10 miles from Mont-Saint-Michel.

The European Union will unveil a proposal this week calling for $73 billion (50 billion euros) in research over the next decade into improving wind, solar, and nuclear power technologies, as well as the development of carbon capture and sequestration projects and energy-efficient “Smart Cities.”
The report, prepared by the European Union’s executive body, the European Commission, says the surge in investment is necessary if Europe hopes to meet its goal of slashing greenhouse gas emissions by 80 percent by 2050.

An amazingly high percentage of people who live down the Mid-Atlantic Seaboard from New York to Virginia want wind turbines off their coast.
Even if they can be seen from the shoreline, 67 percent support off-shore wind power, according to a new poll of coastal residents of New York, New Jersey, Delaware, Maryland, and Virginia .
If the turbines are out of sight, the level of support goes up to an astounding 82 percent.

With steady growth in wind power capacity each of the last five years, China is expected to pass the United States as the fastest-growing market for wind installations this year. But this may only hint at the potential for wind energy in China, according to a new study published in the journal Science.
After modeling China’s wind availability and profitability, researchers from Harvard University and Tsinghua University in Beijing calculated that wind resources, particularly in the country’s northern and western regions, could meet all of China’s electricity demands until at least 2030.
