Four months ago, Andrea Rossi demonstrated what he claims was a one-megawatt "Energy Catalyser" -- or E-Cat -- which produces power by cold fusion. This technology, also known as Low Energy Nuclear Reaction (LENR), had been consigned to the deepest cellar of fringe science.
Now it's hammering on the cellar door, and Nasa, MIT, Darpa and Cern are among those peering through the keyhole, wondering if it should be allowed back in with respectable science. As part of Wired.co.uk's continued coverage of progress in this controversial field, we have investigated recent developments.
Nasa
Nasa has started giving very mixed signals on cold fusion. After years of silence on the issue, a piece appeared on its website stating that LENR tests carried out at Nasa's Glenn Research Centre "consistently show evidence of anomalous heat," indicating that cold fusion was taking place. There is also a link to a paper given at an LENR Workshop held at Glenn in September 2011. However, when questioned, a Nasa spokesman stated out that there was no Nasa cold fusion project, and no budget for it. The work appears to be carried out on the side by interested Nasa scientists.

Even more dramatically, on 16 January a video appeared on Nasa's Technology Gateway site, essentially a marketplace for commercialising technology developed at Nasa. This featured Dr Joseph Zawodny talking about his "Method for Enhancement of Surface Plasmon Polaritons to Initiate & Sustain LENR." In this Dr Zawodny says the technology has the potential to provide home heating and electricity, cleanly and without nuclear waste.
The video release was quickly followed by a long post on Dr Zawodny's blog explaining that he was expressing his own views on LENR and not those of Nasa. In response to the clamour from Rossi's fans, he stressed that he was not yet convinced the E-Cat works: "I am unaware of any clear and convincing demonstrations of any viable commercial device producing useful amounts of net energy."
Steven Krivit of New Energy Times used the Freedom of Information Act to get details of more Nasa LENR presentations and clearly there's quite a fan club there.
Cern
Meanwhile Cern is holding a colloquium on LENR, scheduled for 22 March. This will be available live via webcast, and will be given by Francesco Celani from the Italian National Institute of Nuclear Physics.

Cern is of course a major bastion of mainstream science; a search of Cern's site shows just eight papers on cold fusion compared to over 8,000 on conventional hot fusion. The colloquium seems like inviting a heretic to preach in a cathedral. A recent presentation shows that Celani is a strong advocate for LENR, suggesting that the challenge now is understanding exactly how it works. (He also states that Rossi's claims, though not impossible, need independent verification)
MIT
MIT, which played a key role in discrediting the original cold fusion studies in 1989, might also be shifting its position a little. This January for the first time there was a short course called "Cold Fusion 101." This was taught by Peter Hagelstein, who has been working on LENR for many years. According to are port in Cold Fusion Times, the course included a working demonstration of LENR showing measurable excess of heat.

DarpaDarpa, the Pentagon's Defence Advanced Research Projects Agency, has been quietly pursuing LENR for some years. Its budget plans for next year, released earlier this month, listed some significant achievements: "Continued quantification of material parameters that control degree of increase in excess heat generation and life expectancy of power cells in collaboration with the Italian Department of Energy. Established ability to extend active heat generation time from minutes to 2.5 days for pressure-activated power cells."
