I am sorry to report that there has been a considerable decline in interest in cold fusion. The number of Google alerts about the subject is far lower than it used to be. The number of people reading papers at LENR-CANR.org is down. The numbers usually goes down in summer when students take a break from universities, but this year the numbers are particularly low. See:
http://lenr-canr.org/wordpress/?page_id=1213 Results from Google Ngram are less conclusive. Apparently the term "LENR" meant something in the 19th century and it was for more common than it is today. Both "LENR" and the phrase "cold fusion" have fallen in popularity. https://books.google.com/ngrams/graph?content=lenr%2C%22cold+fusion%22&year_start=1840&year_end=2017&corpus=15&smoothing=3&share=&direct_url=t1%3B%2Clenr%3B%2Cc0%3B.t1%3B%2C%22%20cold%20fusion%20%22%3B%2Cc0 Zoom in: https://books.google.com/ngrams/graph?content=lenr%2C%22cold+fusion%22&year_start=1980&year_end=2008&corpus=15&smoothing=3&share=&direct_url=t1%3B%2Clenr%3B%2Cc0%3B.t1%3B%2C%22%20cold%20fusion%20%22%3B%2Cc0 (Note that the latest data is from 2008.) - Jed
