All you have to do is join the next CC and you can directly question SBs character. He opens the floor for any and all questions. "Realism" is nothing but perspective, like opinions which are like a$#holes. SB saw a self-charging drivetrain prototype and was wowwed enough to sink his money and time into it and is in the process of procuring the remaining equity partners to get it built, 4 of which have already been confirmed per SBs EGC presentation.
All i can say is dont sell yourself short on this one. This will be a headscratcher a few months down the road - possibly weeks. Maybe you can still find some flipping opportunities along the way though.
