A Homemade Wind Turbine (Free Energy)

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".. 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: 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 ...
