I agree, can the son be a dodo sure, but these others are already successful and their reputations are worth much more to volunteer to be tied to a penny scam worth almost nothing, JMO
What I don’t understand is why bother building these, why wouldn’t you hand it off to a manufacturer that is set up already and let them handle it? There is and will be demand for this for the next 10 years. The timing is so I just don’t see even if your a complete idiot how you could screw this up.
People here keep going on about not having the funds to build these. IMO you could get as much money as you needed in days given the circumstances. To me that is not a challenge but the easiest part. Or sell the IP, it will never be worth more
