Re chromosphere Try this one out (meant to add it to previous post): http://science.nasa.gov/ssl/pad/solar/the_key. Good simple site and very simple explanations about MHD and other solar weather effects. Thanks for the link. I can imagine there is lots more to the MHD aspect of the sun.
Montana and Wyoming have lots of coal and MHD based electricity generation is on the news once in a while.
