Many body effects, many theories

Is it time to throw away the gasoline cans because of the energy revolution?  We are still waiting.  Seems like everyone is looking for the one single answer that fits all observations.

excerpts from natscience.com:

• What fuels the E-Cat? Rossi states that he uses micrometer grain
  sized nickel dust enriched to contain more of two useful isotopes,
  N-62 and N-64. 
• The nickel is then processed to increase the number of
  surface tubercles (protrusions) to provide greater area for heat
  producing reactions with hydrogen gas under pressure. A secret
  catalyst is added to break apart the molecular hydrogen gas (H2) into
  atomic hydrogen (H1).
• To make it simple, what happens is that nickel has a
  particularity that protons spread from it's surface with extreme
  efficiency very close to the nucleus, even if repelled by the so
  called coulomb barrier forces. When we inject protons of hydrogen at
  high pressures and temperatures, they go pretty close to the nucleus
  of the nickel. At those points we have nuclear effects that produce
  gamma rays which add more energy. We increase the pressure leading to
  extremely high pressures... similar to ones that happen inside White
  Dwarf stars. In that situation the so called Gamow Factor, which is a
  probabilistic calculation of the coulomb repelling forces, is
  overcome. At that point enough energy is produced to make it worth
  being recorded." - Andrea Rossi

Comment:

It can be recalled that the phenomenon LENR or "cold fusion", is a surface phenomenon.   Rossi's quote above fits with idea of maximizing the surface area.   Maximize the surface area, maximize the effect.

BECNF theory posits that there is a many body effect on the surfaces.  Same with Widom Larsen's theory- relying upon the actions of quasiparticles on surfaces, which corresponds somewhat with BECNF theory.  

There are many theories about "cold fusion".  It has been said that there are too many.  So, I pose the question, as I heard Edmund Storms posed in a similar vein, what if there is more than one way to skin the nuclear cat?  Many body effects, too many causes?  [ those last questions may be too cute, sorry]
