Wouter,
When in Zandvoort in August I noticed a wind farm off shore to the north. I didn't notice it back in 2004. Doesn't mean it wasn't there, but I didn't notice it.
Do you know when that went in and are there more planned.
It would be a lot nicer if they could put something similar under the water and use the current that is generated up and down the cost by the tide movement.

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
