re: Tesla....PBS
The Tesla PBS website is an excellent resource.
Tesla is one of my favorite inventors. Having spent some formative years in Colorado Springs, I was always interested in the short time he spent there. I have been looking for a copy of "Colorado Springs Notes" for years now, but it is out of print and hard to find now.
Tesla has a couple of walk on appearences in Pynchon's last book, one scene in Colorado Springs.
