I emplaced a 60-foot tower this spring, atop that I have a massive (260 lbs) pedestal and on that my solar panels. My initial plan was for a wind turbine there, but plans changed. Jenny and I built the tower piece by piece by not and bolt and lock washer.
But climbing that thing and performing the finishing wiring for the solar panels was one of the most difficult feats I ever have had to perform. The triangular plate I had built - 1/2" steel - became awfully small up there in the stratosphere. The idea of 1,700 feet is really too much.
All the same, I have been to the Far End Of The Earth - Attu Island, the westernmost point of the USA. 1,500 miles west of Anchorage, to give you perspective. And there stands one of the monster towers - I think it's about 1,300 feet - and I know one of the gentlemen who raised that Erector set. It is part of the USCG Loran systems. Attu receives some of the most severe weather on this or any other planet - I discovered a buoy far larger than me tossed about 350 feet up a sea cliff so sheer I could barely climb it.....how would you like to have to change a light bulb atop THAT tower!?!?!?!?!?
