Plywood wind turbine blades? 

Author:  | Photos, Safety, Technology

These wind turbines are placed in Izu peninsula of Shizuoka prefecture, which is about 120 km from Tokyo.

Two turbines were destroyed by lightning in April.

A member of Higasi-izu town assembly took these photos.

He said there was plywood in the blades (which can be see in the photos). In general it is said that wind turbine blades are made of fiber-reinforced polymer. But in fact these are made with plywood inside.

The turbines were made in Germany or Denmark (not Japan).

[The blades were made by LM Glasfiber, and the wood is probably balsa.]
