Building Fiber Glass Blades

http://practicalaction.org/docs/energy/blades_manual.pdf

This report belongs to the same Department of International Development UK project in Sri Lanka.  But, it specifically addresses the fabrication of fiber glass blades.  This may be applicable if there is a wind-rich area where a local entrepreneur(s) wants to expand the business to multiple charging stations.  There may be a business case for hand building a mold and import fiber glass materials.  The blades will be lighter and stronger than that made of wood.  If we are building larger diameter turbine, say 12-15 feet for better cost-effectiveness, this may be a good choice.
