Today, I'm enjoying a very good book about the young Thomas Alva Edison when he was 10-15 years old. I just came across this fun anecdote that I can't resist sharing. It reminds me of the many threads we get here on PF asking about novel ways to generate electricity. By the way, that linked book is free on Amazon or Project Gutenburg. p.s. I couldn't decide whether to make the title of this thread sound like Young Frankenstein or Schrödinger's cat. . If anyone else has anecdotes about Thomas Edison, feel free to reply. Be sure to link your source.
