Ronny Mac had been promising...Commercialization of the zincair battery in 6 to 18 months since the day he joined this Zimtu scam called Zinc8. That was over 3 years ago. His predecessor Jared Lazerson said the same almost 5 years ago when MGX screwed it's shareholders over purchasing ZincNyx from Teck. This so called startup had been around in some shape or form for about 10 years and has produced absolutely nothing. Beware the Zimtu effect and do your due diligence. The fact [paid promotional message] is once again producing paid propaganda videos for Zinc8 should be a huge red flag as proactive is just another paid with your investment dollars shill for a company that produces nothing.
