Past the shortwave radio antennas of World Harvest Radio International, parabolic antenna of the Universal Space Network of the Swedish Space Corporation, small cottages and the Hawaiian savannahs, lie the Kamaoa and Pakini Nui wind farms.

The old windmills have rusted and broken and create more nesting sites for birds than power from the force of the tropical winds.

The scene is eerie, chilling, a snapshot from a post-apocalyptic dimension.

The abandoned blades still creak and moan in the ocean breezes, and the barbed wire warns passers-by in no uncertain terms to stay out.
