I posted the first ngram search incorrectly. Ngram is case sensitive unless
you check the box on the right. Plus, I think I should not have put "cold
fusion" in quotes. I am not sure how the quote sign works in ngram.

Here is a new search comparing LENR (all caps) to "cold fusion" (no quotes):


"Cold fusion" is much more popular. Putting "cold fusion" in quotes makes
them about equal. I do not know what that means.


The 19th century word was "lenr" (lower case). I do not know what it meant.
