The Geek World Wants to Know: Is L.E.N.R. feasible?

Low Energy Nuclear Reaction (LENR), table-top fusion, cold fusion... whatever you know it by has been lighting up the science and innovation websites over the past couple of years.  Scientists are now saying that it is possible, and a few have even replicated the experiment, and even fewer more are building LENR machines for commercial distribution.   Now with all of that said, why is there still doubt that it works and where is the plain speak break-down of the process?

I'll start by highlighting that I am not a physicist.  However, that isn't to say that I don't have a weak grasp of the ideas, and understanding (albeit limited one) of quantum mechanics and the standard model, nor am I unable to figure out an equation given enough time and data.  So where is the proof?

The end result being a relatively safe, low cost, low maintenance personal power plant that should fit nicely into any garage much like a water heater (spoiler alert) and provide us with more than ample electricity and/or heat for our lives.  I would hope that with someone on the verge of releasing LENR power to the world at an amazingly low cost ($1000 per home unit) that scientists in the field would have risen up to prove or disprove this theory, application, or invention...  however, the best we can get are big names from C.E.R.N. or competing companies to come in and explain that it's plausible but some thing "weird" is happening there.  That isn't much help when this technology is released and we are either:

Best case scenario:  An influx of large, cheap, easy, safe power is made ubiquitous.  Our economies will immediately go into a quick turbulent upheaval, and governments will be hard pressed to redefine energy policy globally.

Worst case scenario:  It's fake and a few hundred thousand to millions of people get duped by one of the best con artists of all times.  So why is this the "worst case" scenario?  One fact has been handed out, one truth where there needs to be many but one defining truth, fusion or some effect resulting in energy excess is happening.  If Andrea Rossi's E-Cat is a hoax then the detriment to this field of study will be near irrevocable, even during a time when many scientists believe it is feasible without knowing a mechanism with which to make it commercial.

So here are the "clarion call" questions the laypersons need answered:

Is there a reaction able of generating collectable, usable excess energy in the L.E.N.R. process?

Is it feasible, at this point in time, to make this commercial?

In your opinion (and we need a lot of opinions here) will we see this as a usable technology in a few years?

We need the introverts to speak up.  We need the subject matter experts in the field of physics to "break it down".
