Zap also utilizes the services of paid stock promoters to help boost their share price.
As I said I'm not a financial expert or a lawyer and to the best of my knowledge, they are doing nothing illegal. However, the string of abortive ventures over the last several years combined with these financial transactions does little to inspire any confidence that the Zap-X will ever be anything more than the EV equivalent of Duke Nukem Forever. Forbes Jonathan Fahey has some more details on the numbers behind Zap including their recent $79 million "order" for electric vehicles.
