he might be trolling yaknow
Unfortunately, he has been propagating this idea for a few years now, and it doesn't seem like "trolling" so much as "self-promotion." I suspect he's hoping to score a deal with a "Tesla" or "Google" to promote their electric, self-driving vehicles. Unfortunately, he's too short-sighted to know what he's really talking about.
A friend of mine was working in Agriculture Engineering on near-self managed planters - like tractor-planters. In his modest opinion, they are at least 20 years away from GPS and sensor-controlled agriculture, and that doesn't even begin to address the idea of electric machinery.
The Ag industry is just now starting to adopt UAV's to replace crop dusters, which are a dying art & that's a move out of necessity, not convenience. The rail industry still relies on diesel-electric locomotives. Long-haul trucking is almost 100% diesel, with the remainder running gasoline and propane, definitely not electric. City busses took a page from rail and run bio-diesel engines driving electric motors.
His grandeur vision is just BS to even the slightest scrutiny, and every time he poops up, it's more extravagant and ridiculous - now it's 8 years huh. Then, a bunch of suckers invest in Tesla, or Chevron, or GE, or whatever he's promoting, and he disappears for a few months. It's the sham-wow of shams. Wow.
