UP Keep: the one thing that the so called renewable fanatics never mention.
Stuff wears out and stuff out in the element wears out quicker. The Veteran Hospital in St. Cloud, Minn., had a big wind mill to provide its electricity.
It ran for part of one year before its first break-down; they got it running briefly before it shut-down again. It sat for at least five years, unused and broken, before it was finally torn down, at a LARGE expense.
A fair number of farms/shops in the boonies up here had the smaller ones , but still large ones , when Fleet Farm used to sell them , but a lot are now gone, or when I drive by, often, not working.
The only one I saw run for years, was one that was probably from the fifties or earlier as it was t he old style wind mill from pre-WW II days, and you could see it was running an enclosed generator.
This gent also had his own true fifty foot tall water tower and he was gent who ran a, for profit, machine shop out in the boonies. I spoke to a person about him once and his equipment was the pre-WW II type that ran on storage batteries.
Sadly he shut down, or died, about ten-fifteen years ago, and I miss when I drive by where his shop was, admiring his set-up.
