My IEEE e-mails included an interesting link for once.
What Martin Fleischmann and Stanley Pons saw in 1989 may have been energy r elease, but not from the source they imagined.
Lewis Larsen wanted to explain it (back in 2006) as a hydrogen atom to neut ron conversion, with the energy release coming from the subsequent neutron capture in an adjacent heavy metal nucleus (which would release energy).
Having a proton capture a nearby electron and turn into a neutron sounds ju st as improbable as cold fusion, but it is claimed that the investigators a re starting to get consistent experimental data. Cynics might suggest that this more likely means that there's a venture capitalist in there somewhere , looking for more funding ...
