I DID NOT BUILD THIS OR MAKE THE VIDEO, just posting it bcz I encourage everyone to invest in their own. This is a test run of the guys newly made wind turbine. If these links do not work, just google “Build your own Wind Generator”.. www.thekevdog.com www.instructables.com www.forcefieldmagnets.com Output depends entirely on wind speed, windy days will yeild more power. smaller units 5′-10′ average 50-500 watts larger units 11′-20′ produce on average between 500 watts-up (professionally 21′ and larger up to 7.5 Kw and up) Power is defined as the rate at which work is done or energy is consumed. The formula for average power is acquired by dividing work by the time needed to perform work: P = W/t. Power has units of newton-meters per second or joules per second or watts A kilowatt-hour is the electrical energy consumed in one hour at the constant rate of one kilowatt. The average household in the United States uses about 8, 900 kilowatt-hours of electricity each year. Here are some math formulas to consider…(source: www.awea.org Because air has mass and it moves to form wind, it has kinetic energy. You may remember from science class that: kinetic energy (joules) = 0.5 xmx V2 where: m = mass (kg) (1 kg = 2.2 pounds) V = velocity (meters/second) (meter = 3.281 feet = 39.37 inches) Usually, we’re more interested in power (which changes moment to moment) than energy. Since energy = power x time and density is a more convenient way to express the mass of flowing air, the …

When industrial wind turbines which are 40 stories tall are sited too close to people’s home there is trouble with noise and shadow flicker. Wind developers deny these problems exist and in the state of Wisconsin want to put them 1000 feet from houses. That’s 350 steps. This video shows what happens when wind turbines are irresponsibly sited. The nation is slowly waking up to the downside of wind energy. Developers lie to residents about the impacts these machines will have on the landowners and neighbor’s lives. They take advantage of those of us who want to do the right thing for our environment by telling us there will be no problem with noise, no problem with shadows, and no problem with putting turbines in bird migration flyways. The truth will out, eventually. For the residents in the town of Byron, Fond du Lac county, the truth is what they live with every single day. There is a place for wind energy. It’s just not beside a person’s home.

Just launched! Watch our stunning new time-lapse video of the construction of 3 wind turbines at Bristol Port. The turbines will produce over 15 million units of new green electricity annually, enough to save around 13000 tonnes of carbon emissions every year for the next 30 years! www.ecotricity.co.uk

David Kidney MP, Parliamentary Under Secretary of State for energy and climate change, unveiled the uk’s first wind turbine training tower at Narec, Blythe.
