Actually I think Lynn has a point, if it is on one's mental map of what is real, then it may more readily be perceived by that person.
The problem with the ki as energy question is how do we separate "ki" energy from other forms of energy?
Then again, if we take the qigong definition that "ki/chi exists everywhere and in all things" then maybe the reason why we can't separate and define what "ki" is as energy, is because it is the common thread that exists in all forms of energy at some level. Sort of the basic template from which different manifest forms of energy (which we can detect) originate. This may have something to do with the myriad definitions we get from different people.
Alternatively, I've heard of people refer to what may be termed as "an absence/lack of ki" in training. Often referring to lack of focus, intent, energy etc. Maybe if we can define what ki is not, then we can define what it is.
Just some thoughts.
