The company has no products. AKA they are by definition UNSUCESSFUL! Some of the lead scientists who have left the company say the technology is fundamentally flawed and can't scale. They have spent much less because they weren't working towards actual commercialization, they were always working for paychecks while selling a story in hopes of one day selling the company outright if they could get the technology close enough. No one is buying what they are selling except naïve and gullible shareholders.
