Get Some German Engineering (Not Just for Your Driveway)

A revolutionary design, patented blades and an extremely high output ratio — these are the main features of a micro wind turbine truly “Made in Germany” but without the associated cost of most of the VW models people put in their driveways these days.

The BreezeBreaker 500 is under 5 ft (1.5 m) in diameter and costs under $1500. Developed by a 19-year old inventor from Hannover, Germany, this turbine has the lowest weight-to-output ratio in the world and undercuts Japan’s Zephyr Airdolphin Z1000-25 and Airdolphin GTO™ “next generation” models by roughly one third.

It did not take very long for the “next generation” to start looking like a rather old one: BreezeBreaker 500 by 19 years old Fritz Unger does not only sport a sensational weight-to-output ratio (just 11.875 grams per Watt of rated power) but also makes clever use of rotor physics: 2-blade designs are generally far superior to more blades as 2-blade rotors reduce blade turbulence and suffer significantly less wind energy loss.
