Which is fine.
It was designed like that at the behest of the local population. It was a tribute to a national hero.
However, impressive as it is, it neither generates noise nor does it move. It is a monument. A stationary tribute to a great man - 51meters high.
Here it is.. to get some scale from it - look at the relative size of the people at the base.
Remember this monument is only 51 metres high. Now imagine it twice as tall. Then add another half a column. Until you get about 125 meters. Two and a half times the height of Nelsons column. Then, instead of having the thing in the concrete environment of London, stick in the countryside, preferably up on a ridge so it dominates the whole county.
But don't stop there add another 4 or 5 all the same height, in a line. Not oppressive enough for you?
OK - lets get them to make unpleasant pulsating noise called amplitude modulation. Finally, in case nobody has noticed them, place a large rotating rotor on each one.
Practically speaking, they will (just like Nelsons column) be pretty damn useless for generating electricity.
Remember though, each of these things is two and a half times the height of Nelsons Column above.
If you are going to build these enormous and hopelessly ineffective wind turbines and especially of you reckon they are harmless and "majestic" why not build them in London?
Say, next to Nelsons Column. Or perhaps in Hyde Park. Maybe put a few down the sides of the Mall.
But no. Of course that would never happen. It is much easier to impose them on the countryside. Blight the lives of the yokels. Dare I suggest that if they were to be built in London it would not be long before they came to an untimely (though very welcome) demise.
