All of the ideas on this page are ideas conceived as needs have been perceived. As with any idea, there is the question of originality and ownership.  No patent search has been made for the ideas stated, and they are listed as concepts that need to be explored by further research.  They are offered freely and, as far as I know, are my ideas alone.  As for my permission, you need none. However, in order to ensure that these ideas are not similar to those of another person who may have legal rights, the standard patent or copyright research would be needed.   Again, if it were to be found that an idea found on this web site was created into a viable product or service, etc., it would be appreciated if the source "windmillworks.com." were credited.
