On my way out to check the Sandy-cut breach of Fire Island Sunday, I stopped in to see the site of Wardenclyffe, Tesla's final laboratory. I had long known this site was somewhere in the area (it turns out I had even ridden by it on my bike and didn't even know it!), and with the very successful campaign to acquire the property and build a museum, I figured it was a good time to visit. Tesla had the lab and a nearly 200 foot tower built in the early 1900's, and it became part of his tragic undoing.
The tower was unfortunately demolished in 1917, and the site eventually became a photo products factory which was cleaned up in the 1990's and is currently owned by Agfa. The Tesla Science Center at Wardenclyffe is in negotiations to buy the site (I donated, and you should too!). That's a great project, but it's going to be a lot of work, as you can see:
