Telsa Man Out of Time

This is kind of a random one, but I read Tesla Man Out of Time. He was an engineer at the end of the 1800s and start of 1900s (around the same time as Edison). Tesla invented the original AC motor/generator which enabled AC power (the stuff you get out of the wall socket). While Marconi is usual given credit for RF (wireless), Tesla actually figured it out first. He did a whole bunch of other stuff including creating Tesla coils (a way to get huge voltages - if you ever see a big metal thing with lightening bolts coming out of it, it is probably a Tesla coil). The book was interesting although much heavier on his life and light on the details on his stuff worked. If you've never heard about the whole fight between AC and DC it is kind of interesting. Edison wanted to distribute DC and Westinghouse wanted to distribute AC. AC was obviously better (after Tesla made his addition), but Edison wouldn't give up so he tried to make AC look dangerous by electrocuting animals with AC in public and arranging to have the electric chair use AC.
