The blueEnergy Turbine
• Base design from Hugh Piggott of Scoraig Wind Electric; school of “heavy metal”
• Significant design inspiration from Otherpower.com
• Designed from the ground up for ease of construction, robustness and optimized for energy production in low winds
• Axial-flux alternator vs. more common radial-flux designs
• Ease of construction -> ease of maintenance -> low-cost over lifetime
