We’ve post a few articles on Randell Mills and Brilliant Light Power, formerly Black Light Power and the hydrino theory.  If their reported progress is real, Mills and BLP may indeed be the most promising alternative energy to watch.
LENR may be tangental to Mills’ research or perhaps the LENR effect is being confused with the waste heat produced by Mills’ hydrino formation theory.  The basic theory is that through a chemical reaction, a hydrogen atom can be altered to a different state where the electron drops into a lower energy state and the resulting excess binding energy is released as light and x-rays which can be harvested through photovoltaic cells.
