Somewhat ironic that interest in LENR has an ~11 year period... which is also seen in the sunspot cycle... ... which really isn't exactly 11 years, but... somehow it manages to be a very good fit over time.
One 'big picture' irony lies in the fact that solar energy itself has become surprisingly affordable, such that the imperative to find cheaper energy via LENR has withered, at least to a degree. Yet, as of recently, the sunspot cycle has been statistically pegged to two overlapping cycles which average out to 11 years over the long term - and which also predict a coming "maunder minimum" (little ice age) to happen relatively soon - which makes this 11 year period a double irony in a way. https://www.nextbigfuture.com/2018/11/winter-is-coming-super-grand-solar-minimum.html Curiously, despite the science involved in solar activity prediction - and the proof which is found in ice cores - the particular sunspot cycle result is hugely controversial with weather "experts" ... who - on the one hand, want to bring science into the picture at the expense of politics, but only so long as the science fits into their belief structure. In short, and in the context of political correctness... an upcoming little ice age starting in 2020 tends to negate the 'global warming' credo... which admittedly does not factor in solar activity correctly. IOW - there could be an emerging argument that the formerly negative result of climate change for the next generation of humans at least, may be "right for the wrong reason" and positive. Sure, it may be too soon for the "experts" to jump ship and to predict this, especially since the sunspot cycle science comes from China and Russia and not the USA. OTOH, the method used by them does predict the last little ice age accurately -1645. Maybe that is coincidental.

It peaked after 11 years in 2013. If present trends continue, it will fall close to zero around 2024. The bottom graph, Google Trends Interest over time, shows that interest in cold fusion is asymptotically falling to zero.
