COMPANY CLAIMS SAFER ALTERNATIVE TO WIND TURBINES

Avoiding controversy over government support for alternative
energy, Cheyenne based Prudencia LLC, has introduced sustainable technology that produces electricity for as little as 6 cents per kWh, less than half what most Americans pay. Prudencia is a selling agency of vertical axis wind turbines manufactured by Change Wind Corporation of Jewett City, Connecticut. www.changewind.info.
Unlike the monstrous subsidy-dependent horizontal axis wind turbines (HAWTs) on wind farms, a Change
Wind turbine typically stands only 30 feet. Instead of blades spinning like a pinwheel, the CWC turbines
use a helical wing design than can produce power from a turbulent breeze from any direction.
Innovated patented mechanical advances inspired by auto racing technology make the Change Wind turbines super-efficient, producing electricity in 6 mph breezes, reaching optimal power production at just 12 mph, generating 36kW.
The Change Wind turbines are a green power solution that’s not only sustainable, but even happens to be more economical than conventional power. “It’s good for the environment, and great for business,” says Prudencia co-founder, Ronald Terrazas. At $59,950, FOB Jewett City, CT the Change Wind 36kW turbine is economically viable even without government subsidies or tax breaks. 
Big wind turbines stir opposition from nature conservation advocates who disparage them as hulky, ugly, noisy bird killers. But at just 30 feet tall the Change Wind turbines are lower than many trees and roof  lines. They capture turbulent air from all directions. Birds seem to perceive the spinning wings as a solid vibrating object not to be flown into or landed on. 
Another compelling argument for CWC turbines is “distributed generation,” producing electricity close to where it is actually consumed, reducing need for long transmission from centralized generation. Besides the stresses from increasing demand from a burgeoning population, the United States’ power transmission grid is susceptible to cyber-attack and physical sabotage. “Disable the transmission grid and pretty soon you can’t pump gas, harvest crops, operate cash registers, process electronic transactions, or deliver fuel and food to the cities. Massive civil unrest would quickly follow a sustained grid failure,” says Prudencia co-founder, Michael Ferrara.
Widely dispersed Change Wind turbines offer a practical supplement to utility grid power. They can operate for decades with very little maintenance. According to Jim Bardia, Change Wind founder, “maintenance is more or less just an annual oil change.” Because the 36kW is low, and quiet, there is little public resistance and few zoning prohibitions preventing it. 
In areas of steady breezes one 36kW can power up to 10 standard households. In less developed countries, one turbine could power a small village. The CWC turbines can be paired with a battery that stores power for when there is no wind. Finally, there is the option to link the turbine to the utility grid, selling excess power to utility companies on so-called “net metering” arrangements.
Change Wind turbines have been developed and operated since 2009. Repurposing a shuttered hydro-electric powered wire factory in Connecticut, Change Wind has installed modern computer numerical control (CNC) machinery to produce the 36kW.
Prudencia also arranges programs called “power purchase agreements” (PPAs) that enable investors to capitalize micro-utilities that sell cheap power to consumers on a fixed term contract. In states that give
special preferences to alternative energy systems the economics get even better.
