"Tesla" tech

[Ashtagon]

I'm working on an alternate world timeline where Tesla's technologies (with allowances for gaming purposes; I'm more after entertaining fiction than hard science) have taken off.

What I'm not sure of is what technologies he actually designed but never got developed. There's the whole broadcast power thing which i am aware of, but not sure what else.

I could just default to some variant on Atlantis-style tech, but I'd rather aim for things that Tesla is actually reputed to have done.

Where's a good place to research this?
