nobody knows when the purchases will come
even the engineers inside the companies that may purchase don't know when they will convince the guys with purse strings, let alone GDGI, far less the stockholders
but i think the purchases will come before or after the company goes bankrupt but before it dissolves
would EPA, Harvey Mudd, Tulane all endorse if it did not work?
sooner or later the very conservative HVAC businesss will catch on and this will not so much catch fire as create fission
BOOM!
so hold. if it makes you happy to think someone can guess when it is coming, knock yourself out. just please don't be sad if it turns out the CEO and the stockholders are looking at shadows on the cave. sooner or later, this tech will be a rock solid money-saving, profit-earning powerhouse.
