Visiting the ruins of a wave power plant — waves running up a funnel to fill a reservoir

Using wave energy to generate electricity sounds very attractive, after all there are tons of waves and all they do (in addition to looking pretty) is eroding coast lines. But that’s exactly the problem: There is a lot of energy in waves, so wave power plants have to be extremely tough.

Here is another post about the ruins of the wave power plant I visited on Toftøy. For an idea on the size of the waves on this not-very-windy day with fairly moderate waves, check out the movie at the end of this post (there are two people that you might be able to spot on the rocks on the other side, and those pillars used to carry a bridge). 

Below you see the waves entering a funnel that will lead them slightly uphill…

…so the water can fill up reservoir which is located higher than sea level…

…in order to drive turbines when the reservoir is emptied out again into the sea.

You already see the huge amount of energy stored in those waves, and looking at how little is left of the power plant, it’s definitely safer to stay well clear of those waves!

Check out in the movie below what it looks like when waves enter this power plant (and pay attention to the two people on the rock on the other side — they clearly didn’t expect that much energy in the waves! :-D)
