At last SHM I briefly talked to JF how his brother was doing. He said (Aug, 2015) that DF had read 45 books and has been working on some ideas he has. With anything technology being DF's passion, it is safe to say his ideas are now patents pending as previously eluded to by F-21. There is coming a tech revolution with mems leading the way (100 microelectonicmechanisms chips can fit on a dime). The internet of things talks about MEMS revolution and how it will effect everything within next four years. We are living in exciting times.
