After a rather extended vacation from trying to design wind powered electricity generators I was back at it today. My latest rough outline includes hanging a doubled set of hoops -- one inside and one outside -- from the same hoop above it. Within the two circles would be a circle of circles. That is, a set of coils around the central circle.
I was thinking today of how a fellow squared the circle as I was cutting watermelon rind away to get to the fruit. I was thinking that housewives square the circle often while peeling fruit....
So anyway, the trick to this design will be to provide stable yet lightweight platforms on the two moving hoops in order to mount magnets that can be somehow waterproofed -- also in a lightweight fashion.
The central circle also needs to be protected from the elements while simultaneously not allowing much distance between the central circle and the circles on either side of it.
Ho hum. So much to do....
Oh yes. Another trick: keeping the two magnet circles from grabbing each other, even though the magnets should be pointed in exactly that direction. How to keep them apart enough to send their flux through the coils, without letting them touch the coils or each other? Have I chosen an impossible task this time?
Later Note (6 a.m. 9/24/15): Yes. This is impossible, given the horizontal wobbles inherent in the whirligig's spin. Even if I were to insist on rounded corners on the edges of my magnetic circles, and/or sides high enough to prevent the circles from cutting the central circle; indeed, even if wrapped in antistatic cloth, friction would fray the cloth and/or cause too much drag on the device. The cloth would also collect debris over time and be cut eventually.
So, I revisit old design ideas every so often with the effect that I recheck those designs in light of any new information I might have obtained during the interim. This is much the same process I have observed myself performing as I remember family events out of our past experiences. Dreams do this, too, I think.
I should make a separate entry for the following, but I already provided the segue. I am reading Developing a Social Psychology of Monkeys and Apes by John Chadwick-Jones. It provides -- so far -- a very organized review of research on this topic. I love how the topic shows the overlapping of Psychology and Anthropology in what we call in the states Physical Anthropology and Comparative Psychology. The somewhat new overlap here is between Social Psychology and Physical Anthropology.
This book should be sent back to the library from which it came, and I intend to do that after I have either read it or found a non-library copy. Bolton University of the UK seems to have lost it to an Amazon book-seller in the U.K.
(Later Note, 10/6/15: After being attacked by unseen but biting and roaming critters while first reading the second Appendix to the book over a week ago; and again experiencing the same event last evening after reading Appendix one -- after finishing the book -- I have decided to do my best to get this book incinerated by Waste Management. Sorry, Bolton University, but you do not want this book to return to you. I will send a note to them to this effect.)
