While some countries are just starting to gear towards harnessing wind energy, others are already replacing old turbines with newer models.

The Danish Port of Aalborg has come up with an innovative re-use idea, namely 'carving' a bike shed out of a discarded blade. Well, easier said than done!

The port's Brian D. Rasmussen, a civil engineer by training, had to do a lot of troubleshooting. The midsection of the blade, courtesy of the nearby Siemens Gamesa, needed to be cut and 'gutted' in such a way that it wouldn't fly away nor break the cantilevers, crashing the bikes.

What's more, Rasmussen didn't have access to a detailed design of the blade, so he had to do some weekend small-scale experimenting with cardboard and wood.

But finally, with the help of local blacksmith and diamond drilling companies, an old wind turbine blade was given new life, safely sheltering bikes under its wing.
