How might the many inventions of Nikola Tesla changed society and the way the 20th Century played out?
Let's say, for example, that Tesla is hired by the US government upon him leaving Edison. Say he develops all of his inventions (provided they were practical) and imagine that market forces allow them to be applied. What does the world look like, and how did it get that way?
EDIT: Having Tesla live and work in another country to make this more feasible would also be interesting.
