"Have you ever heard of even one person in the U.S. harvesting and burning peat?"
Yes, kind of. Link below is not to one up you, but as a child growing up in rural Illinois, I remember a peat fire in one of my uncle's fields on more than one occasion. Takes for ever to put out - just smolders - may just burn itself out. I was pretty young.
One of the links mentions harvesting peat - this search only asked for Illinois, not the US or even the Midwest.

I grew up in Illinois and have similar memories. See my post #25.
