A few words of thanks to persons that are voluntary testing the idea investing their time and expense, motivated principally by curiosity, I have been surprised by the positive reaction. “I genuinely want to finding out for myself if this works” (JM) is a typical response.

For any that wish to participate (the more the better) I will repeat the request/offer that anybody that wishes can reproduce the experiments and prove me wrong (or right)
I am told it is customary that volunteers receive some sort of “perk” for their effort, the first 20 persons that try one of the above experiments(regardless of results) will receive 10 shares of a soon to be created company (startup as it is the fashion these days) under the conditions outlined here.
