It's the dunk tank.
This is where you come to post big-brained hot takes by chuds, libs, or even fellow leftists, and tear them to itty-bitty pieces with precision dunkstrikes.
Rule 1: All posts must include links to the subject matter, and no identifying information should be redacted.
Rule 2: If your source is a reactionary website, please use archive.is instead of linking directly.
Rule 3: No sectarianism.
Rule 4: TERF/SWERFs Not Welcome
Rule 5: No ableism of any kind (that includes stuff like libt*rd)
Rule 6: Do not post fellow hexbears.
Rule 7: Do not individually target other instances' admins or moderators.
Rule 8: The subject of a post cannot be low hanging fruit, that is comments/posts made by a private person that have low amount of upvotes/likes/views. Comments/Posts made on other instances that are accessible from hexbear are an exception to this. Posts that do not meet this requirement can be posted to !shitreactionariessay@lemmygrad.ml
Rule 9: if you post ironic rage bait im going to make a personal visit to your house to make sure you never make this mistake again

first of all, considering any technology's efficiency in a vacuum is nonsense, so jot that down. If trains are efficient because the infrastructure already exists, then they are efficient, full stop.
second, that's not an opinion, it's just wrong. Trains are a way to move a maximum of weight along a predetermined route continually for a minimum operating cost. Maybe their only competitor is pipelines, and that only works for fluids. In every complex system the easiest way to reduce overhead is by bundling operations. Shipping everything in North America by long haul truck would require less coordination, but it would also cost more labor power, take more time, and destroy the environment more.
This idiot isn't actually a PhD, is he?
Ah. So literally just some guy that paid for twitter.
Scratch that, he's a guy that's trying to build a train but worse, and he probably got an email telling him he has to pay for twitter.
e: Also he has a fake company trying to bilk investors with a magic bullet perpetual energy machine. The dickriding is spectacular
