Yes (note: most people who have replicated it distinguish it from "cold fusion" - obviously this is controversial.)

In 1994 Thermacore, under contract by the US Air Force, observed anomalous heat: http://www.lenr-canr.org/acrobat/GernertNnascenthyd.pdf

In 1996 the CERN observed both (1) excess heat (however they theorize it is caused by local variations of its thermal characteristics) and (2) hydrogen absorption (which they concede is unexplained): http://lenr-canr.org/acrobat/CerronZebainvestigat.pdf

In 2011 Celani observed excess heat: http://www.newenergytimes.com/v2/conferences/2012/ICCF17/pap...

There are some other groups who have reproduced it but the quality of their research vary a lot (for an overview see http://nickelpower.org/2011/12/30/replicators-as-if-december...). The problem is that it remains still hard to replicate. Zawodny (from the NASA Langley Research Center) has some theories about why, see slide 17: http://newenergytimes.com/v2/government/NASA/20110922NASA-Za...

No, but people for some reason still believe him after he has spent the past few years making up excuse after excuse for why it couldn't be tested independently.

It's complete bullshit. https://en.wikipedia.org/wiki/Cold_fusion

The article you link to actually shows references to a lot of scientific experiments that are actually showing excess heat. No where it proposes the idea of room temperature fusion is bullshit or even impossible at all.

>Many scientists tried to replicate the experiment with the few details available. Hopes fell with the large number of negative replications, the withdrawal of many positive replications, the discovery of flaws and sources of experimental error in the original experiment, and finally the discovery that Fleischmann and Pons had not actually detected nuclear reaction byproducts

What's up the reading comprehension today?
