Though the Dutch are known for their windmills, they may be looking to underwater turbines for energy in the near future.
In 1953 a massive flood decimated a large part of The Netherlands, killing 1,800 people on the south-west coast of the country. Dikes were devised and installed along the coastline to prevent future flooding. In their wake they left a host of man-made freshwater lakes — now stagnant and home to unpleasant algae — and shut the tides out of the large estuaries. A group of engineers is now proposing a plan to cut a few holes in the structures to allow the saltwater to return. The revised dikes would reinstate natural habitat and could create a network of tidal power plants that would provide electricity to the region.
