Green Energy Technologies (GET), a company based in Akron, Ohio, USA, is introducing a unique wind system (with 1MW, 500kW, 100kw and custom rooftop models) called the SmartEnergy Spire, which creates a ‘wind tunnel’ effect forcing the wind around the Spire. Using the Bernoulli principle, the Spire design creates an efficiency of 1.676 two times the throughput over a traditional wind turbine using ambient wind.
