Zinc8 does not have a working product - virtualwareTil such time as Zinc8 can prove that they have an actual working product you are right now buying nothing but hot air. Some people will make money off of hot air and others will lose. Without a working product even in small scale demo form in the lab or at Surrey House what exactly is it you are investing in right now?
I also have a virtual working time travel machine which is way cooler than the virtual Zinc8 ZincAir battery if you want to be part of something huge. Of course I cannot show it to anyone yet because like the Zinc8 ZincAir battery it is only virtual and doesn't actually exist in a working real life form but seems a lot of people like investing in virtualware/vaporware these days.
