Thanks, Burr

I will keep on posting as this one develops and will post any of them when I use MoI for design development. I have been working on this book for some years now but keep getting diverted with 'real' projects. It sure looks like the construction industry is slowing down for awhile and I am looking forward to time to do some focusing on writing and new (for me) design ideas. I did a lot of energy efficient design in the late 70's and early 80's and then oil got cheap again and clients were no longer interested in spending capital now for savings in the future.
I have an energy efficient 'green' development in the early design stages but the developer has placed a 'hold' on it.

and so it goes,
