NonTypical,
Not sure how cloud cover here in MN during the winter compares to MI. I have gotten a few PM's as well about sharing my very simple desgin. So, I will be taking pic's of my setup this weekend and post under the aeration section.

Disclaimer, I know enough about solar power and aeration to be dangerous. There are others here that know volumes more than I do on both subjects. I am just a garage inventor who likes to share his experiences. grin
