Windspire: 1 kW Wind Turbine for Your Backyard for $4,000

Windspire Turbines are innovative in design with a bladeless rotor that can produce 2,000 kilowatt hours per year. It costs $4,000 for a 1 kW Wind Turbine rated unit that is easy to install and can be connected to a computer with a wireless modem and monitor its output. It produces enough power for an average home.

It is 30 foot tall and 2 feet wide, the propeller less design is relatively quiet, even at high speed it produces 25 decibels of noise at five feet, equivalent to the average noise of a residential neighborhood at night. An average turbine produces a noise level of 65 decibels or more, compared to that Windspire noise levels are less. It is bird safe, and it takes only a minimum wind speed to make it spin, an 8 mph wind is sufficient to make the turbine operate and can withstand wind speeds up to 100 mph.

The cost maybe high in terms of return on investment, at $4,000 and at 10 cents a kilowatt, it will take about 20 years to get any returns. But for an average home, it will meet all the power needs so one doesn’t have to pay utility bills.

Mariah Power who produce these Wind Turbines claims they are easy to maintain. The plastic rotor panels and inverter can be easily replaced if necessary.

Compared to relying on coal power this wind power is far better. If homeowners combine together, they can invest and provide electricity for their homes and sell the remaining to the power companies.
