Production facility is in Tunisia and operational. I would think it would be more rational to bring the prototypes to North America for approval prior to investing millions in a facility. $500K could buy back 25-30% of the float. $500K for a state of the art facility is peanuts compared to what it will cost to build/convert a space suitable for their needs.
Buyback at these levels will not be an option after the news starts to hit the airwaves. PPS will hit .005 on news of a buyback. Halfway to QB status.
$500K @ .002 will be $2.5 million at a .01. Short term investment with a 5 fold return. Makes better sense in the longterm IMO.
